Types of Elastic Load Balancing (ELB)

KomalLM — Sat, 17 Feb 2024 14:41:39 +0000

When I was preparing for my AWS Solutions Architect - Associate (SAA-C03) exam, I found so many good topic that I want to share. One of them is Types of ELB.

So here are few question that click in my mind:
What is ELB ??
Are there 3 or 4 types of ELB ??.
Do we use all types, when and where ??

So here are my finding on this topic.

ELB - Elastic Load Balancing. ELB automatically distributes incoming applications traffic across multiple targets such as Amazon EC2 instances. This can be done across multiple AZs.

Types: 3 or 4 ??

There are 4 types of ELB.

Application Load Balancer - ALB
Network Load Balancer - NLB
Gateway Load Balancer - GWLB
Classic Load Balancer - CLB
Are we using all ???

No CLB is a Legacy and so it is deprecated. But AWS encourages users to migrate to ALB or NLB - Why ?? See Details of each LB.

Application Load Balancer - ALB :

Routing HTTP/HTTPS traffic
Support Websocket
ALB Operate on Layer 7 of OSI Model. 7th Layer is Application Layer of OSI Model.
Intelligent Load Balancers

Network Load Balancer - NLB :

Routing TCP,TLS,UDP,TCP_UDP traffic
NLB operates on Layer 4 of OSI Model. 4th Layer of OSI model is Transport Layer.
It can handle millions of request per second. So when a user need to route thousands or ten thousands of concurrent connections they need NLB.
Performance Load Balancer

Classic Load Balancer - CLB :

Legacy load balancer.
Load Balance for HTTP/HTTPS traffic.
Use Layer 7 OSI Model specific features such as X-Forwarded & sticky sessions .

Gateway Load Balancer - GWLB :

Routing IP traffic
GWLB operates on Layer 3 of OSI Model. 3th Layer of OSI model is Network Layer.
GWLB used to deploy, scale and run third-party virtual appliances like custom firewalls. More details on third-party appliances can be found here:

Third-party Virtual Appliances

KomalLM — Mon, 12 Feb 2024 00:47:04 +0000

What is Third-party Virtual Appliance, and where it is used in AWS Cloud ??

Third-party virtual appliances: The pre-configured virtual machines images, that are provided by third-party venders and are ready to deploy in virtual environments are called "This-party virtual appliances".

Virtual environments can be VMware, Hyper-V, VirtualBox, or cloud platforms like AWS, Azure and Google cloud Platform.

Virtual appliances are designed for various purposes like application delivery, monitoring, networking or security.
For example virtual image that have specific service like pre-installed and configured service for security that can be deploy in any virtual env.

Third-party virtual appliances provide ready to use solutions for various problems. Some examples of third-party virtual appliances are firewall appliances by Cisco, Database appliances from Oracle etc.

package-lock.json

KomalLM — Sat, 27 Jan 2024 13:54:13 +0000

package-lock.json: What is it and why is it important? Why you need to commit this file?

package-lock.json is a JSON file that contains the dependencies for a Node project.

This file is important because it ensures that everyone working on the project has the same dependencies installed.
Why Does Npm Create A Package-Lock.json File And When?

Create a package.json
npm init
In the image below, I am creating a default package.json under a folder called LearningPath
Open package.json and see what is this one: cat package.json
If you do ls you will only see package.json because there is no dependency install, now lets install some dependency like jest
npm install jest , this will install latest version of jest as well as all dependiencies of jest
Check list of file in the folder , by ls command, you will see one folder node_modules , package-lock.json and package.json
All dependent packages get installed into "node_modules" subdirectory .
package-lock.json: This file got created after installing packages and it have more json data then package.json, because it contains the data that actully specifying what is the exact versions of every package that got installed. There is very important reason for this file.

Importance of package-lock.json:

so as you will see that jest package is dependend on so many other packages like: jest-cli.
So when you install jest 23.6.0, it install jest-cli 23.0.0 and other packages, But few days later one of your coworker installs that same project and then they install, they actually get jest-cli 24.0.0 because a new version has been released in the time since you installed. Now there's difference between your two installation directories and that can sometimes you into trouble, And so the package-lock.json file's purpose is to specify exactly what versions were installed and you check that file into source control and everybody else uses that same package-lock.json.
npm install first check for package-lock.json to install the packages and if the package-lock.json is not present it checks in the package.json.
So when they do the typical flows of just running npm install. npm install will look at the package-lock.json file and install those specific versions and that makes sure that everybody on your team is running off the same exact versions of all packages , so you don't get any weird issues where something works for one person, but not for another.

AWS CloudFront S3 Static Website

KomalLM — Fri, 20 Jan 2023 19:52:59 +0000

CloudFront: AWS CloudFront is a web service that delivers contents in the network, also called as Content Delivery Network (CDN) service. CloudFront web service
speeds up distribution of static and dynamic web content like .html, .css .js and images to the user.

Content delivery network of edge locations.
Caches static files for lower latency meaning contents is served closer to the request origin. for example when a user requests a content that you are serving with cloudFront, the request is routed to the edge location(world wide network of data centers) that provides lowest latency.
Offloads websites by caching stuffs.
Integrates well with AWS S3
Offers HTTPS

Lets see how we can use that in the Static Web site:

What is Static Web site: Static web site is a website with fixed content and all viewers will see same content. Example of static web site is like if i just need to show my art work and my content info, if anyone like my artwork can email me. Pretty straight forward, upload images to website and that it.

1. Create a S3 bucket

Create bucket

Enable public access by uncheck Block all public access, and select acknowledge as shown in following screen shot.

Enable static Website hosting: Once bucket is created , go to property, scroll down to "Static website hosting" and click on Edit -> click on enable, checked off Host a static website, add name of main html and the error html. Click on Save Changes.

Once you save these changes, scroll down and you can see a S3 Website URL. This URL can be accessed publicly, and contains s3 bucket name but it is not s3 bucket URL.

If you click this URL it will give you 403 forbidden error , because we did not attached a bucket policy to this s3 bucket.

Enable right policy for your bucket- object hosted by the website bucket must be publicly readable, which means s3:GetObject allowed on it. Following screen shot shows the policy.

Upload an object to s3, so create a simple HTML file and upload to s3. Now click the link again, go to property tab of s3 , scroll down n click on the URL again.

No server-side code execution

Only client-side scripting and web pages can be hosted.

CloudFront > - Open CloudFront and click on "Create distribution" or "Create a CloudFront distribution" > - Origin Name: select S3 website endpoint , > - Select all default values and click on "Create Distribution" > - Wait for this to be deployed and mean while update the S3 policy as follows, add your , and

{
    "Version": "2012-10-17",
    "Id": "Policy1673481402657",
    "Statement": [
        {
            "Sid": "AllowCloudFrontServicePrincipalReadOnly",
            "Effect": "Allow",
            "Principal": {
                "Service": "cloudfront.amazonaws.com"
            },
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::<Bucket-name>/*",
            "Condition": {
                "StringEquals": {
                    "AWS:SourceArn": "arn:aws:cloudfront::<AWS-Account#>:distribution/<dis-ID>"
                }
            }
        }
    ]
}

Hit the URL > - Once distribution is deployed it will give you a link under "Distribution domain name", that is your new URL to host your Static Website.
