Why Create Custom Docker Images?

Custom Docker images give us control over application configurations and dependencies, improving security and performance. We can create a custom Docker image tailored to our own needs, with the dependencies we want, and the code we want.

For example, we want everybody in our dev team to use Ubuntu 24.04 with Apache and the code in one GitHub repo. We could create a custom Docker image, upload it, and tell everybody in the dev team to work using that image.

No more dependencies problem, no more "I don't know how to install X" and, especially, no more "But it works on my computer".

We just need to create one image packaged with all we need, that executes every step we want.

Doing the process steps manually

One tip before creating our own custom Docker image is to do the process manually: We get a clean Linux system (a Virtual Machine created with Vagrant is an easy way as you can use the image and discard it later) and we run the commands we want.

Using a process of trial and error, we install and configure everything we want until it is done. We will repeat these steps on our Docker image.

For this, of course, you need to have Docker installed (and, if not, here's how to Install Docker).

Let's start then!

We want to run a Flask web application inside an Ubuntu OS. The steps we want to do are:

Install Ubuntu
Install Python and its required tools
Create a Python virtual environment
Install Flask dependency
Copy our Python code
Run the Flask web application

So, let's start!

First, let's download a Docker image, then create a container using that image, and run the bash terminal:

docker run -it ubuntu:24.04 bash

Now we are in the container's terminal as root. Let's install our dependencies:

apt update

apt install -y python3 python3-pip python3-venv

Ubuntu 24.04 uses an externally managed Python environment, so instead of installing Flask directly into the system Python, we create a virtual environment:

python3 -m venv /opt/venv

Activate it:

. /opt/venv/bin/activate

Now install Flask:

pip install flask

Now we have everything we need to run our code.

You can create a Flask app, search for one on GitHub that you want to use, or just use an application I have created for this tutorial.

Copy the code and paste it inside /opt/app.py.

import os
from flask import Flask

app = Flask(__name__)

@app.route("/")
def main():
    return "Welcome!"

@app.route("/How are you")
def how_are_you():
    return "I'm fine, how about you?"

@app.route("/about")
def about():
    return "I'm just a small Flask app :)"

@app.route("/info")
def info():
    return "I have been created just to pass Pau's subject."

if __name__ == "__main__":
    app.run()

Everything is set, time to run the server!

/opt/venv/bin/flask --app /opt/app.py run --host=0.0.0.0 --port=5000

Now the Flask server is listening on port 5000 inside the container.

Creating our Docker image

We have our server running perfectly. Now, we want to reproduce the same steps in a Docker image so we can distribute it.

First, close everything and check the container isn't running:

docker ps

Now, let's create a folder for us to work in. Inside, create a Dockerfile (a text document that contains all the commands we want to run) where we will create a script to do all the steps we did before:

mkdir app_flask
cd app_flask

vim Dockerfile

Our Dockerfile will contain:

FROM ubuntu:24.04

RUN apt-get update && \
    apt-get install -y python3 python3-venv && \
    rm -rf /var/lib/apt/lists/*

WORKDIR /opt

COPY app.py /opt/app.py

RUN python3 -m venv /opt/venv && \
    /opt/venv/bin/pip install --no-cache-dir flask

EXPOSE 5000

CMD ["/opt/venv/bin/flask", "--app", "/opt/app.py", "run", "--host=0.0.0.0", "--port=5000"]

The important difference from our original Dockerfile is that we use a Python virtual environment. This is appropriate for current Ubuntu releases, where Python packages should not be installed directly into the system-managed Python environment.

We also use the exec form of CMD. Docker supports both shell and exec forms, with the exec form providing clearer process and signal handling. EXPOSE documents that the application listens on port 5000; it does not publish the port to the host by itself.

Now we can run Docker build to run the script and create a Docker image. But before, as we see in the COPY line, we need to have our script in the same folder. Copy it or just download it with wget:

wget https://raw.githubusercontent.com/david1707/flask-app/main/app.py

Now build the image:

docker build . -t david1707/app-flask-caminas:1.0

Remember to change the image's name, following the convention of <YOUR_NAME>/<IMAGE_NAME>.

I have also added the 1.0 tag so that we can identify this version of the image. If no tag is specified, Docker uses latest by default, but explicit version tags are useful when you want to distinguish different image versions.

After the build completes, you have your custom Docker image.

Now let's run it:

docker run -d \
  --name app-flask-caminas \
  -p 5000:5000 \
  david1707/app-flask-caminas:1.0

Now we can visit:

http://localhost:5000

The Flask application is running inside our Docker container.

Making public our Docker image

Now we can distribute the Docker image and everybody will have the same image, with the same dependencies.

We can publish it in a Docker repository, for example, in Docker Hub. Very much like GitHub, Docker Hub allows us to store and share container images.

You have to register in Docker Hub first, then log in:

docker login

If your image isn't already tagged with your Docker Hub username, tag it:

docker tag david1707/app-flask-caminas:1.0 <YOUR_DOCKER_USERNAME>/app-flask-caminas:1.0

Then push it to Docker Hub:

docker push <YOUR_DOCKER_USERNAME>/app-flask-caminas:1.0

Docker's current documentation uses this same workflow: authenticate, tag the image with the Docker Hub namespace and repository, and then push the tagged image.

Now anyone with access to the repository can use your image with:

docker run -p 5000:5000 <YOUR_DOCKER_USERNAME>/app-flask-caminas:1.0

This will download the image if it isn't on the computer and run it.

Now we can visit:

http://localhost:5000

Final thoughts

Creating our own Docker images is pretty easy. We just need the basics of using the terminal, then we can replicate all the steps in a Dockerfile to create our images, even distributing them via Docker Hub.

The benefits of using our own custom Docker images are:

Customization: Creating and using your own Docker images allows for tailored configurations, ensuring that the image contains specific dependencies, settings, and optimizations that align with the requirements of your applications.
Security Compliance: By building and managing your own Docker images, we have direct control over the inclusion and configuration of security measures and dependencies.
Reduced Image Size: Customizing Docker images allows for the elimination of unnecessary components, resulting in smaller image sizes. Smaller images can lead to faster deployment times and more efficient resource utilization.
Flexibility and Specialized Tooling: Building our own Docker images provides the flexibility to incorporate specialized tooling or unique requirements specific to your organization's workflows. This customization lets teams create and deploy applications with the exact environment they need.

Docker Basics for Beginners: A Complete Guide

Ritesh Kokam — Mon, 03 Aug 2026 14:31:35 +0000

If you've searched for Docker, you already know it's described as a software platform that uses OS level virtualization to produce self sufficient containers. That's accurate, but it's not exactly beginner friendly language. Let's break it down in plain terms, with commands you can actually run today.

What is Docker?

Docker lets you package an application and everything it needs to run (code, runtime, libraries, system tools) into a single unit called a container.

Think of it in two parts:

Image. A read only template or blueprint used to create one or more containers. It's essentially a recipe.

Container. A running instance of an image, isolated from other containers, with its own filesystem and environment.

If you've used Oracle VM VirtualBox or Vagrant before, Docker will feel familiar. You pick an image, spin up an instance, and work inside it. The difference is how Docker does this under the hood, and that's what makes it faster and lighter than a traditional VM (more on that below).

Here's a minimal Dockerfile, the instructions used to build an image:

FROM ubuntu:24.04
RUN apt-get update
RUN apt-get install -y curl nginx

This tells Docker to start from Ubuntu 24.04, update the package index, then install curl and nginx. Build a container from this image and you get a ready to use Ubuntu environment, already updated and pre loaded with curl and nginx.

Because every developer on a team builds from the same image, everyone gets the same OS, the same package versions, and the same behavior. The "but it works on my machine" problem effectively disappears.

Docker vs. Virtual Machines

If a Docker container behaves like a mini virtual machine, why not just use VMs?

The key difference is that Docker containers share the host machine's kernel instead of virtualizing an entire guest operating system. That makes containers dramatically lighter and faster to start, often in a second or two, compared to the minutes a full VM boot can take.

This matters most when you're shipping code. Say you're building a Node.js app on a specific Node version. You can:

Create a Docker image starting from a base OS
Install the exact Node.js version and dependencies your app needs
Share that image with your team or deploy it to any Docker compatible server

Nobody has to manually match package versions or babysit a deployment checklist. The server's underlying OS, installed packages, or programming language don't matter. Docker runs the image as is. Upload the image, run it, and you're deployed.

What's New in Docker Right Now

If you last touched Docker a while back, a few things have changed:

Docker Engine 29.x is the current stable line, having succeeded the 28.x series. It ships with security fixes, an updated runc and RootlessKit, and changes to how concurrent image pulls and pushes are throttled by default.

Docker Compose is on the v5 line (currently v5.3.0), with ongoing improvements to docker buildx bake, build resource limits (--resource), and source policy validation for build image authenticity.

docker sandbox has been removed in favor of docker sbx. Update any scripts or docs that still reference the old experimental sandbox plugin.

Docker Desktop's Logs (Beta) view now surfaces directly from docker logs, compose logs, compose attach, and compose up, giving you a unified log panel across running containers.

Ubuntu 26.04 LTS ("Resolute Raccoon") is now supported alongside 24.04 LTS and 22.04 LTS in Docker's official apt repository.

Docker has also continued shipping regular CVE fixes across the engine, Desktop, and the Model Runner AI component. If you're running Docker in production, keeping current with point releases matters more than ever. Check the Docker Engine release notes before upgrading in any CI or production pipeline.

Installing Docker

You can install Docker Desktop (GUI) or Docker Engine (CLI only). Both are actively maintained, so pick based on your workflow rather than any old "real developers use the terminal" bias.

Full, OS specific instructions live at:

For Debian based distros (Ubuntu 22.04, 24.04, or 26.04):

Remove any old versions first:

sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd

Install Docker via the official convenience script:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh ./get-docker.sh

Verify the install:

sudo docker version

Run a test container:

sudo docker run docker/whalesay cowsay boo

If that prints an ASCII whale saying "boo," Docker is working.

Running Docker without `sudo` (do this the safe way)

By default, every Docker command needs sudo because the Docker daemon socket is owned by root. The usual fix is adding your user to the docker group:

sudo usermod -aG docker $USER
newgrp docker

Log out and back in (or reboot) for the group change to take effect, then test with docker run hello-world. No sudo needed.

A note on security: you may see older tutorials suggest running sudo chmod 666 /var/run/docker.sock to skip the sudo prompt. Avoid this. It makes the Docker socket world writable, which is basically equivalent to giving any local user root access to the host, since Docker containers can mount the host filesystem. Adding your user to the docker group gets you the same convenience without that exposure. If you need tighter isolation altogether, look into rootless Docker (dockerd-rootless-setuptool.sh install), which runs the daemon itself without root privileges.

Basic Docker Commands

A cheat sheet of the commands you'll use daily:

Task	Command
List downloaded images	`docker images`
Run a container from an image	`docker run <IMAGE_NAME>`
Run a specific version/tag	`docker run <IMAGE_NAME>:<VERSION>`
Run in the background (detached)	`docker run -d <IMAGE_NAME>`
Reattach to a running container	`docker attach <ID>`
Pull an image without running it	`docker pull <IMAGE_NAME>`
Run a command inside a running container	`docker exec <CONTAINER> <COMMAND>`
Open a shell inside a container	`docker run -it <IMAGE_NAME> bash`
List running containers	`docker ps`
List all containers (including stopped)	`docker ps -a`
Map a container port to the host	`docker run -p <HOST_PORT>:<CONTAINER_PORT> <IMAGE_NAME>`
Inspect an image or container (JSON)	`docker inspect <NAME_OR_ID>`
View a container's logs	`docker logs <NAME_OR_ID>`
View an image's layer history	`docker history <IMAGE_NAME>`
Stop a running container	`docker stop <NAME_OR_ID>`
Remove a container	`docker rm <NAME_OR_ID>`
Remove an unused image	`docker rmi <IMAGE_NAME>`
Build an image from a Dockerfile	`docker build . -t <NAME>`
Set an environment variable	`docker run -e <VAR>=<VALUE> <IMAGE_NAME>`
Adjust CPU/memory of a running container	`docker container update --cpus 2 --memory 512m <NAME>`

A couple of examples in context:

# Inspect the OS release info inside an Ubuntu container
docker run ubuntu cat /etc/*release*

# Run a container that sleeps for 15 seconds, then exits
docker run ubuntu sleep 15

# Pass an environment variable to an app image
docker run -e APP_COLOR=blue simple-webapp-color

To connect one container to another (say, a web app that needs Redis), the modern approach is a user defined network rather than the legacy --link flag:

docker network create app-net
docker run -d --name redis --network app-net redis
docker run -d -p 5000:80 --name voting-app --network app-net voting-app

Containers on the same network can reach each other by container name. No --link (deprecated) required.

Real World Example: Running Jenkins in Docker

Jenkins is a widely used CI/CD automation tool, and it's a great first "real" container to run.

docker run jenkins/jenkins        # download and start Jenkins
docker ps                         # get the container ID
docker inspect <CONTAINER_ID>     # get the container's internal IP

To reach Jenkins from your host machine's browser, rather than only inside a VM, map the container port to a host port:

docker run -p 8080:8080 jenkins/jenkins

Now open http://localhost:8080 in your browser. If you're running Docker inside a Linux VM on a Windows or Mac host, the chain looks like this: host machine, then Linux VM, then Docker container.

Port mapping is what lets a request from your host browser reach a lightweight container running two layers down.

Data Persistence with Volumes

Stop the Jenkins container, come back the next day, restart it, and your setup screens, jobs, and configuration are gone. What happened?

Containers are ephemeral by default. Jenkins stores its data at /var/jenkins_home inside the container, but running the image again creates a brand new container with a fresh filesystem. Your old data isn't there.

Option 1: Bind mount a host folder

mkdir my_jenkins_data
docker run -p 8080:8080 -v /home/<USERNAME>/my_jenkins_data:/var/jenkins_home jenkins/jenkins

This links a folder on your host (my_jenkins_data) to the container's /var/jenkins_home. Anything Jenkins writes there persists on your host disk, so restarting the container, or even recreating it, picks up right where you left off.

Option 2: Docker managed volumes

Instead of tracking a host path yourself, let Docker manage storage under /var/lib/docker/volumes/:

docker volume create test_volume
docker run -v test_volume:/var/lib/mysql mysql

Or using the more explicit --mount syntax:

docker run --mount type=bind,source=/data/mysql,target=/var/lib/mysql mysql

Named volumes are generally preferred for production because Docker handles backup, migration, and driver plugins (think cloud storage backends) for you.

Frequently Asked Questions

Is Docker still relevant, or has something replaced it?
Yes. Docker Engine and Docker Compose continue to receive active development and regular security updates, and Docker images remain the de facto standard supported by essentially every cloud provider and CI/CD platform.

Do I need Docker Desktop, or is Docker Engine enough?
Docker Engine (CLI plus daemon) is sufficient for servers, CI runners, and Linux native development. Docker Desktop adds a GUI, a Kubernetes toggle, and extra tooling like Model Runner for local AI models. That's mainly useful on macOS and Windows, or if you just prefer a visual interface.

What replaced docker sandbox?
docker sandbox was an experimental plugin that has since been removed. Use docker sbx instead.

Is it safe to run Docker without sudo?
Yes, as long as you add your user to the docker group rather than loosening permissions on the daemon socket directly (see the security note above). Membership in the docker group is functionally equivalent to root access on the host, so only add trusted users.

What's the difference between -v and --mount?
Both attach storage to a container. -v (or --volume) is shorter and more common. --mount is more explicit and verbose, and it's generally recommended for Swarm services or when you need fine grained control over mount options.

Final Thoughts

Docker earns its popularity for a handful of concrete reasons.

It gives you real isolation, running applications insulated from the host system and from each other. It's efficient, since sharing the host kernel means far less overhead than full VMs. It's portable, because an image runs the same way on any Docker compatible host. It's scalable, letting you spin up more containers to handle more load and scale back down just as easily. It keeps things consistent, moving the same image from a developer's laptop through CI to production and eliminating environment drift. It plugs into a huge ecosystem of tools, Docker Hub, Docker Compose, Kubernetes, and a massive library of official images. And ultimately it simplifies deployment: you ship an image, not a checklist of dependencies to install by hand.

Understanding the Top 7 Frontend Security Attacks

Ritesh Kokam — Tue, 30 Jun 2026 14:00:47 +0000

In the digital age, securing web applications is of paramount importance. Every day, over 2,200 cyber-attacks occur as a result of poorly designed web applications. Here, we delve into the top seven common frontend security attacks and how to prevent them.

1. Cross-Site Scripting (XSS)

Cross-Site Scripting, or XSS, is a prevalent attack where malicious client-side scripts are injected into trusted websites, which are then executed in the user’s browser. These scripts can access and steal sensitive information stored within the browser, such as cookies, session tokens, or other sensitive information that the user might have entered into the website.

Prevention: To prevent XSS attacks, it’s crucial to validate and sanitize forms and input fields that allow users to insert data. This means checking that the data is of the correct type, length, format, and range. Additionally, implementing a Content Security Policy (CSP) can restrict resources and scripts that are loaded. Modern JavaScript frameworks like Angular, Vue, and React have built-in preventive mechanisms against XSS attacks.

2. SQL Injections

SQL Injections manipulate database queries to gain unauthorized database access. Attackers can execute SQL Queries from your frontend, leading to destructive actions like dropping your database.

Prevention: To prevent SQL injections, it’s important to validate and sanitize frontend input fields and backend payloads. This means checking that the data is of the correct type, length, format, and range. Using parameterized queries or prepared statements can also help prevent SQL injections. Additionally, tools like Burp Scanner, sqlmap, jSQL Injection, and Invicti can be used to detect potential SQL attacks.

3. Cross-Site Request Forgery (CSRF)

Cross-Site Request Forgery, or CSRF, forces victims to execute unwanted actions in an app they’re logged into. An attacker could trick users with a disguised link that quietly transfers funds from their account using their stored credentials.

Prevention: To prevent CSRF attacks, it’s important to implement anti-CSRF tokens in your application. These tokens ensure that the requests made to your server are legitimate and originated from your website. Additionally, using the “SameSite” attribute for cookies can help prevent CSRF attacks.

4. Clickjacking

Clickjacking uses transparent overlays on a trusted page to trick users into clicking on something different than they perceive. For example, an attacker could overlay a transfer funds button or a cat video’s play button.

Prevention: To prevent clickjacking attacks, it’s important to implement the X-Frame-Options HTTP response header. This tells the browser whether you want to allow your site to be framed or not. Additionally, using framebusting scripts can help prevent clickjacking attacks.

5. Dependency Exploitation

Front-end apps rely on many third-party libraries and components. If these have vulnerabilities, they undermine the whole app.

Prevention: To prevent dependency exploitation, it’s important to regularly update your dependencies and use tools like npm audit or Snyk to identify known vulnerabilities. Additionally, using a package manager that supports lockfiles can ensure that you’re using the correct versions of your dependencies.

6. Security Misconfiguration Attacks

Security misconfiguration attacks exploit default configurations, incomplete or ad hoc configurations, open cloud storage, misconfigured HTTP headers, and verbose error messages containing sensitive information.

Prevention: To prevent security misconfiguration attacks, it’s important to regularly review and update your configurations. Ensure error messages do not reveal sensitive information. Additionally, using a security configuration review tool can help identify potential security misconfigurations.

7. Man-in-the-Middle Attack

In a Man-in-the-Middle attack, the attacker secretly relays and possibly alters the communication between two parties.

Prevention: To prevent Man-in-the-Middle attacks, it’s important to use HTTPS for all your pages. Implementing HTTP Strict Transport Security (HSTS) can ensure the browser only connects to your server via HTTPS. Additionally, using a VPN can help prevent Man-in-the-Middle attacks.

Conclusion

In conclusion, understanding these common frontend security attacks and their prevention methods is crucial for building secure web applications. Stay vigilant and keep your applications safe!

PWA in 2026: Why Progressive Web Apps Still Matter

Ritesh Kokam — Mon, 15 Jun 2026 14:11:42 +0000

The web has come a long way from being a platform for simple websites. Today, modern web applications can deliver fast, reliable, and engaging experiences that closely resemble traditional mobile and desktop apps. At the heart of this evolution are Progressive Web Apps (PWAs).

A Progressive Web App combines the reach of the web with many of the capabilities users expect from installed applications. Users can access a PWA through a browser, install it on their device, receive updates automatically, and in many cases continue using it even when network connectivity is limited.

While new technologies and trends continue to emerge, PWAs remain one of the most practical ways to build and distribute modern applications across multiple platforms.

What Is a Progressive Web App?

A Progressive Web App is a web application that uses modern browser technologies to provide an app-like experience. Unlike traditional websites, PWAs can be installed on a user's device, launched from a home screen or desktop, and offer features such as offline support, push notifications, and access to selected device capabilities.

The concept is built around progressive enhancement. The application works for everyone through the browser while providing additional functionality on devices and browsers that support advanced features.

This approach allows developers to create a single application that serves users across smartphones, tablets, laptops, and desktop computers without maintaining multiple platform-specific codebases.

What Can PWAs Do in 2026?

Modern browsers have significantly expanded the capabilities available to web applications.

Today's PWAs can:

Capture photos, videos, and audio using device cameras and microphones
Access location services for navigation and location-based experiences
Send push notifications to keep users informed and engaged
Support secure authentication methods such as biometrics and passkeys
Open, edit, and save files directly from the browser
Integrate with native sharing features on supported devices
Process payments through modern payment systems
Work offline using intelligent caching and synchronization
Access selected device hardware and sensors where supported
Deliver rich media experiences, including audio and video playback

The result is an experience that feels increasingly similar to traditional applications while retaining the accessibility and flexibility of the web.

Why Businesses Are Choosing PWAs

One of the biggest advantages of PWAs is efficiency.

Instead of building separate applications for Android, iOS, desktop platforms, and the web, organizations can often serve the majority of their users through a single codebase. This reduces development effort, simplifies maintenance, and accelerates product delivery.

PWAs also eliminate many of the barriers associated with app distribution. Users can access the application instantly through a URL and decide later whether they want to install it. This creates a smoother onboarding experience and can improve user acquisition.

Another important benefit is deployment speed. Updates can be released immediately without requiring users to download new versions manually. This enables teams to fix issues, improve performance, and ship features faster.

For startups and growing businesses, these advantages often translate into lower costs and faster time-to-market.

Benefits for Users

PWAs offer several advantages that directly improve the user experience.

Fast and Responsive

Modern caching techniques help applications load quickly and remain responsive, even on slower networks.

Reliable Access

Offline support allows users to continue interacting with content and services when internet connectivity becomes unreliable.

Easy Installation

Users can install a PWA directly from their browser without navigating app stores or downloading large installation packages.

Automatic Updates

Because updates are delivered through the web, users always have access to the latest version of the application.

Cross-Platform Compatibility

The same application can work across a wide range of devices and operating systems, providing a consistent experience wherever users access it.

PWAs in the AI Era

Artificial intelligence is becoming a standard feature in modern software, but it does not change the fundamental value of PWAs.

Many applications now include intelligent search, recommendations, automation, content generation, or conversational interfaces. These capabilities can be delivered effectively through a Progressive Web App while maintaining the advantages of web-based deployment.

The rapid pace of AI innovation has actually highlighted one of the strengths of PWAs: instant updates. Teams can continuously improve features and deploy enhancements without requiring users to install new versions manually.

At the same time, the success of any application still depends on core fundamentals such as performance, usability, accessibility, security, and reliability. PWAs provide a strong foundation for delivering these qualities regardless of whether AI features are included.

Are PWAs the Future?

The debate about whether PWAs can replace native applications has largely evolved into a more practical discussion: choosing the right tool for the right problem.

Native applications still make sense for certain use cases that require deep operating system integration or highly specialized hardware access. However, for many business applications, SaaS platforms, e-commerce stores, customer portals, content platforms, and productivity tools, PWAs offer an excellent balance between capability, reach, and development efficiency.

Rather than being viewed as an alternative to native apps, PWAs have established themselves as a mature application platform in their own right.

Conclusion

Progressive Web Apps have moved well beyond their early adoption phase. They now provide a reliable and cost-effective way to build modern applications that work across devices while delivering many of the experiences users expect from native software.

With features such as offline support, installability, push notifications, secure authentication, and access to modern device capabilities, PWAs continue to bridge the gap between websites and traditional applications.

In 2026, they remain one of the smartest choices for organizations looking to build fast, accessible, and scalable digital experiences without the complexity of maintaining multiple platform-specific applications.

5 Web Design Trends of 2026

Ritesh Kokam — Mon, 01 Jun 2026 14:05:23 +0000

Web design is a dynamic and evolving field that constantly adapts to new technologies, user preferences, and best practices. As we move ahead, the digital landscape has shifted from purely aesthetic choices to deeply immersive, interactive, and high-performance user experiences. Drawing from the latest design shifts observed across major product systems and the Figma ecosystem, the way we experience the web is undergoing a massive transformation. In this article, I'll share with you 5 web design trends that are completely shaping the digital landscape and how you can use them to create stunning, future-proof websites for your clients. Let's get started!

1. 3D & Immersive Elements

Web interfaces have completely broken free from flat, rigid boundaries. Websites are increasingly blending hyper-realistic, fully interactive 3D models directly into structural layout layers to create rich, spatial experiences. Rather than treating 3D elements as background decorations, modern design relies on them as core components of user discovery.

This approach completely reinvents how users evaluate physical or abstract objects online. By leveraging optimized assets, you can deliver these heavy-impact interactive features smoothly on mobile viewports and desktop setups alike.

It elevates online product storytelling by allowing users to physically rotate, disassemble, or manipulate items in real time.
It replaces static imagery with active exploration, dramatically increasing the time a user spends engaged on the landing screen.
It builds an instant perception of high-end quality and tech-forward innovation for a client's brand identity.

2. Ultra-Massive Bold Typography

Typography has stepped past its traditional role of simple legibility to become the primary artwork on the web page. Hero layouts are heavily ditching traditional photo blocks in favor of ultra-massive headlines, custom display typefaces, and fluid letterforms that expand, stretch, or shift weight based on user navigation.

Using variable typography rules allows the text to behave like a living element. Letters can change slant, adapt to container sizes, or even split apart to allow interaction models to seamlessly fit around key conversion text.

It grabs immediate consumer focus inside the critical first three seconds of a page load.
It reduces reliance on heavy imagery, allowing websites to stay performance-focused and visually striking at the same time.
It maximizes native search index crawl performance, as the primary messaging is rendered entirely through accessible code rather than flattened graphics.

3. Kinetic Motion Design & Animation

Static web design feels increasingly obsolete. Current layouts embrace integrated motion design—ranging from delicate micro-interactions to deep, scroll-driven multi-axis parallax animations that react physically to a user's cursor speed and movement direction.

The magic here lies in contextual feedback. Elements don't just flash into view; they glide, scale, or transform based on gravity variables, giving the interface a tactile, incredibly responsive sense of space.

It guides user navigation by using physical movement to highlight essential interactive points, like checkouts and feature highlights.
It transforms mundane data consumption into a pleasant narrative journey that reacts directly to the user's input.
It eliminates jarring, sudden visual jumps by substituting them with elegant structural transformations that keep the user grounded.

4. Gamified Interface Frameworks

To capture and retain shrinking user attention spans, websites are widely borrowing UX mechanics directly from video games. This incorporates active reward metrics, visible challenge markers, progress indicators, and playful interactions that turn typical browsing tasks into engaging digital quests.

Gamification works wonderfully when applied to onboarding funnels, data input steps, or user dashboards. By framing interaction steps as satisfying milestones, user completion rates climb drastically.

It dramatically boosts user interaction and retention rates by appealing to natural behavioral triggers.
It simplifies complex onboarding setups, turning multi-stage question forms into short, enjoyable challenges.
It fosters deep brand loyalty by transforming transactional interactions into personalized user milestones.

5. Soft-Skeuomorphic Neumorphism

Neumorphism has officially matured into a clean, sophisticated design tool. By artfully layering soft, opposing inner and outer shadows with subtle background gradients, this aesthetic crafts beautifully physical, tactile buttons and cards that look extruded from or recessed into the digital canvas.

Unlike the flat design trends of previous years, neumorphic elements present an incredibly smooth, approachable finish. It brings back a digital texture that makes buttons feel truly clickable and inputs feel authentically tactile.

It yields an incredibly soft, unified aesthetic that feels comfortable during extended viewing sessions.
It reintroduces physical depth to flat layouts, restoring a natural sense of interaction priority.
It creates a minimal, ultra-modern luxury feel that is exceptionally well-suited for fine art portfolios, modern dashboards, and fintech products.

Conclusion

The overarching trend in modern web design is crystal clear: Interfaces are becoming live environments. The rigid, static layouts of the past have stepped aside for adaptive, multi-dimensional, and highly engaging digital spaces. By combining immersive 3D, expressive kinetic typography, smooth physics-driven motion, gamified pathways, and tactile soft UI depth, you can build digital experiences that look premium and convert brilliantly.

Exploring Network Security: Firewalls, IDS, IPS, and VPNs

Ritesh Kokam — Mon, 20 Apr 2026 14:00:00 +0000

Network security is a crucial aspect of ensuring the safety and integrity of data and systems in the digital world. With the rapid evolution of cyber threats and the rise of cloud computing and remote work, organizations must go beyond traditional perimeter-based defenses.

Modern security models now incorporate concepts such as Zero Trust Architecture (ZTA), AI-driven threat detection, and cloud-native security solutions. These advancements help organizations detect, prevent, and respond to threats more effectively.

In this blog post, we will explore four key components of network security—firewalls, IDS, IPS, and VPNs—and examine how they have evolved in today’s landscape.

Firewalls: The First Line of Defense

Firewalls act as a barrier between trusted internal networks and untrusted external networks. They monitor and control traffic based on predefined security rules, allowing organizations to enforce access control policies.

Traditionally, firewalls filtered traffic using parameters like IP addresses, ports, and protocols. However, modern environments require more advanced inspection capabilities.

Today, firewalls are commonly categorized as:

Hardware firewalls – Protect entire networks at the perimeter
Software firewalls – Protect individual devices
Next-Generation Firewalls (NGFWs) – Provide advanced capabilities such as:
- Deep Packet Inspection (DPI)
- Application-level awareness
- Integrated IDS/IPS
- SSL/TLS inspection

Firewalls use multiple techniques to analyze traffic, including packet filtering, stateful inspection, and application-level gateways. These methods ensure that only legitimate connections are established and maintained.

In 2026, firewalls are no longer limited to the perimeter. They play a key role in Zero Trust Architecture, where:

No user or device is trusted by default
Every request is verified based on identity and context

They are also widely deployed in cloud environments as cloud-native firewalls and WAFs, protecting distributed applications.

Intrusion Detection Systems (IDS): The Proactive Defense Mechanism

Intrusion Detection Systems (IDS) monitor network traffic and system activity to identify suspicious behavior and potential threats. Instead of blocking attacks, IDS focuses on detection and alerting.

IDS can be deployed in two primary forms:

Network-Based IDS (NIDS) – Monitors traffic across the network
Host-Based IDS (HIDS) – Monitors activity on individual systems

To detect threats, IDS uses several techniques:

Signature-based detection – Matches known attack patterns
Anomaly-based detection – Identifies deviations from normal behavior
Heuristic detection – Uses rules and logic to detect unknown threats

While these concepts remain relevant, IDS has evolved significantly. In modern environments, it is rarely used as a standalone tool. Instead, it is integrated into platforms such as:

NDR (Network Detection and Response)
XDR (Extended Detection and Response)
SIEM systems

These platforms use machine learning and behavioral analytics to detect advanced threats like zero-day attacks and insider threats, making IDS part of a broader security ecosystem.

Intrusion Prevention Systems (IPS): The Next Level of Security

Intrusion Prevention Systems (IPS) build upon IDS by not only detecting threats but also actively preventing them. They monitor traffic in real time and take immediate action to block malicious activity.

IPS can operate in two modes:

Inline mode – Actively blocks malicious traffic
Passive mode – Monitors and generates alerts only

Like IDS, IPS relies on signature-based, behavior-based, and heuristic techniques to identify threats.

In modern security architectures, IPS is typically not deployed as a standalone solution. Instead, it is integrated into:

Next-Generation Firewalls (NGFWs)
SASE platforms
Automated response systems like SOAR

This integration allows IPS to:

Respond to threats automatically
Reduce manual intervention
Improve overall response time

As a result, IPS plays a critical role in automated and adaptive security strategies.

Virtual Private Networks (VPNs): Secure Communication

Virtual Private Networks (VPNs) provide secure communication over public networks by creating encrypted tunnels between users and systems. They are widely used for remote access and site-to-site connectivity.

VPNs are generally classified into:

Site-to-site VPNs – Connect multiple networks
Remote access VPNs – Allow users to connect securely from anywhere

Modern VPNs rely on secure protocols such as:

IKEv2/IPsec
TLS (1.2 / 1.3)
WireGuard (modern, fast, and efficient)

However, some older protocols are now considered insecure:

PPTP → obsolete and vulnerable
L2TP (without IPsec) → not recommended

Despite their importance, traditional VPNs have limitations. They often grant broad network access, which can increase risk if credentials are compromised.

The Shift to Zero Trust Network Access (ZTNA)

To overcome the limitations of VPNs, organizations are adopting Zero Trust Network Access (ZTNA). Unlike VPNs, ZTNA provides access based on identity, device health, and context.

This means users only gain access to specific resources rather than the entire network.

Key advantages of ZTNA include:

No direct exposure of internal networks
Least-privilege access control
Continuous verification of users and devices

ZTNA is commonly delivered through SASE (Secure Access Service Edge) platforms, which combine networking and security into a unified cloud-based solution.

Modern Network Security Trends

Network security today extends beyond traditional tools and includes several advanced approaches.

Key trends include:

Zero Trust Architecture (ZTA) – “Never trust, always verify”
Cloud security solutions – CASB and CSPM
AI-driven threat detection – Behavioral analytics and automation
XDR and EDR – Unified visibility across systems
SASE – Converged networking and security

These technologies enable organizations to build scalable, intelligent, and resilient security infrastructures.

Conclusion

Network security is a continuously evolving field that requires both strong fundamentals and modern strategies. While firewalls, IDS, IPS, and VPNs remain essential components, their roles have expanded significantly in response to new challenges.

By combining traditional security mechanisms with modern approaches such as Zero Trust, AI-driven detection, and cloud-native architectures, organizations can build a robust and future-ready security posture.

Top 10 Vector Databases in 2026

Ritesh Kokam — Mon, 06 Apr 2026 14:10:11 +0000

In the current landscape of Artificial Intelligence, a vector database is no longer a specialized tool—it is the Long-Term Memory for AI agents. As we move toward autonomous reasoning and multimodal AI (text, image, video, and audio), the choice of database defines how well your AI "remembers" and "reasons."

What is a Vector Database?

A vector database is a specific kind of database that saves information in the form of multi-dimensional vectors representing certain characteristics or qualities. Each vector has a certain number of dimensions, which can range from tens to thousands, based on the data's intricacy and detail. This data, which could include text, images, audio, and video, is transformed into vectors using various processes like machine learning models, word embeddings, or feature extraction techniques.

The primary benefit of a vector database is its ability to swiftly and precisely locate and retrieve data according to their vector proximity or resemblance¹². This allows for searches rooted in semantic or contextual relevance rather than relying solely on exact matches or set criteria as with conventional databases.

How is a Vector Database Different from Other Databases?

The primary difference between vector databases and other databases is their ability to store and manipulate high-dimensional data. Vector databases are designed specifically to handle large volumes of data and complex computations such as similarity and nearest-neighbor searches⁸.

Traditional databases store simple data like words and numbers in a table format. Vector databases, however, work with complex data called vectors and use unique methods for searching. While regular databases search for exact data matches, vector databases look for the closest match using specific measures of similarity⁹.

Use Cases for Vector Databases

Vector databases have many use cases across different domains and applications that involve natural language processing (NLP), computer vision (CV), recommendation systems (RS), and other areas that require semantic understanding and matching of data. Some examples include:

Image and Video Recognition: Given the high-dimensional nature of images and videos, vector databases are naturally suited for tasks like similarity search within visual data.
Natural Language Processing (NLP): In NLP, words or sentences can be represented as vectors through embeddings. With vector databases, finding semantically similar texts or categorizing large volumes of textual data based on similarity becomes feasible¹¹.
Recommendation Systems: Whether for movies, music, or e-commerce products, recommendation systems often rely on understanding the similarity between user preferences and item features. Vector databases can accelerate this process, making real-time, personalized recommendations a reality.

9. LanceDB (The Edge & Serverless Disruptor)

LanceDB is an open-source, serverless vector database that stores data in a persistent disk format. It is uniquely designed to run on edge devices or within serverless functions without an always-on server.

Best For: Mobile apps, edge computing, and cost-efficient data lakes.
Key Edge: Blazing fast "zero-copy" reads directly from cloud storage or local disk.

10. Redis / RedisVL (The Speed Freak)

Redis has evolved beyond simple caching. By using RedisVL (Redis Vector Library), it provides sub-millisecond latency for vector lookups, making it the top choice for Semantic Caching.

Best For: Real-time AI agents and high-traffic applications.
Key Edge: The fastest retrieval speeds in the industry for smaller to mid-sized vector sets.

Each of these databases has its own unique features and advantages that make them suitable for different use cases. It's important to choose the one that best fits your specific needs.

Conclusion

Vector databases have evolved from a specialized niche into the essential memory layer for modern AI. Whether you choose a managed powerhouse like Pinecone, a scalable open-source giant like Milvus, or a developer-friendly tool like Chroma, the goal remains the same: transforming unstructured data into searchable, actionable knowledge.

As AI agents become more autonomous, these databases will serve as the bridge between static models and truly intelligent, context-aware systems. The best time to choose your vector strategy is now—start small with pgvector or Chroma, and scale as your data grows.

What is ORM? Let's understand ...

Ritesh Kokam — Mon, 23 Mar 2026 14:06:02 +0000

Object-Relational Mapping (ORM) is a programming technique that allows developers to interact with relational databases using objects instead of writing raw SQL queries.

As of 2026, ORMs are not just abstraction tools, they are part of a broader data access layer that often combines ORM features with query builders and raw SQL when needed. Modern ORMs also emphasize type safety, better performance, and compatibility with cloud-native and serverless environments.

Why Use an ORM?

ORMs continue to provide strong benefits, though how they are used has evolved:

Abstraction of Database Design: ORMs allow developers to work with objects and classes, which are mapped to database tables. This reduces the need to constantly think in SQL and helps teams focus on domain logic rather than schema details.
Ease of Use: Modern ORMs include advanced tooling such as migrations, schema synchronization, validation, and relationship handling. This reduces boilerplate and improves maintainability.
Database Agnostic: ORMs still support multiple databases, but in practice, teams now often optimize for one primary database while relying on ORM abstractions to reduce vendor lock-in where possible.
Type Safety: In modern ecosystems (especially TypeScript), ORMs provide strong compile-time guarantees, reducing runtime errors and improving developer productivity.

How Does an ORM Work?

At a high level, an ORM maps classes or objects in your codebase to tables in your database, where each instance represents a row and each attribute represents a column.

When you perform operations like create, read, update, or delete, the ORM translates these into SQL queries, executes them, and maps the results back into objects.

Modern ORMs also support async operations, provide query optimization techniques like batching and caching, offer flexible loading strategies (lazy and eager), and integrate with logging tools for better performance monitoring.

Advantages

Speeds-up Development: ORMs eliminate repetitive SQL and provide reusable abstractions, making development faster—especially for CRUD-heavy applications.
Reduces Development Costs: Faster development and fewer bugs (thanks to type safety and validation) help reduce long-term costs.
Overcomes Vendor-Specific SQL Differences: ORMs handle many database-specific quirks, though developers may still need database-specific tuning for performance-critical paths.
Improves Security: Modern ORMs use parameterized queries by default, significantly reducing the risk of SQL injection.
Handles the Logic Required to Interact with Databases: ORMs manage relationships, transactions, and schema changes, simplifying application architecture.

Disadvantages

Learning Curve: Developers must understand ORM behavior (e.g., lazy loading, N+1 query problems), which can impact early productivity.
Loss of Control: Abstraction can hide what queries are actually executed, making it harder to fine-tune performance without deeper knowledge.
Performance: ORMs can still be slower than optimized raw SQL, particularly in high-scale systems or complex query scenarios.
Complex Queries: While ORMs handle standard operations well, advanced queries (joins, aggregations, window functions) often require raw SQL or query builders.

Examples of ORMs

There are many different ORMs available for different programming languages. Here are a few examples (reflecting current usage trends):

SQLAlchemy (Python): Still a leading ORM, now with strong async support and flexible query capabilities.
Active Record (Ruby): Continues to be the default ORM in Rails, emphasizing convention over configuration.
Hibernate (Java): Widely used in enterprise applications, often alongside frameworks like Spring Data.
Sequelize (Node.js): A mature ORM, though newer projects increasingly adopt more type-safe or lightweight alternatives.
Prisma (Node.js/TypeScript): A modern, type-safe ORM focused on developer experience and schema-driven design.
Drizzle ORM (Node.js/TypeScript): A newer, lightweight ORM that follows a SQL-first approach with strong type safety.

Conclusion

In conclusion, ORMs remain a powerful tool for developers in 2026, but their usage has become more balanced and pragmatic.

They abstract much of the complexity of database interaction and enable cleaner, more maintainable code. However, modern best practice is to use ORMs alongside raw SQL when needed, rather than relying on them exclusively.

A solid understanding of both ORM concepts and SQL is essential to building scalable, high-performance applications.
