What is AWS? 🌥️

AWS stands for Amazon web services which is owned and operated by Amazon Ltd.

History of AWS? 🏃

Use cases of AWS 🪢

AWS (Amazon Web Services) offers a wide range of services that can be used for various use cases, including:

Web and Application Hosting: AWS can be used to host websites, web applications, and mobile apps.

Data Storage and Backup: AWS provides various storage options, such as S3 for object storage and Glacier for archival storage, that can be used to store and backup data.

Machine Learning and AI: AWS offers services such as SageMaker and Rekognition that can be used to build, train and deploy machine learning models.

Big Data Processing: AWS provides services such as EMR and Redshift that can be used to process and analyze large amounts of data.

Disaster Recovery: AWS can be used to set up disaster recovery solutions, such as replicating data to a different region, to ensure business continuity.

IoT: AWS IoT can be used to connect, manage, and analyze data from IoT devices.

Gaming: AWS can be used to build, host and scale multiplayer gaming experiences.

Media and Entertainment: AWS can be used for video transcoding, storage, and delivery.

Government and Public Sector: AWS provides services that are compliant with government standards and regulations.

Financial Services: AWS provides services that can help financial firms in areas such as risk management, fraud detection and compliance.

AWS Infrastructure

AWS Regions

AWS has multiple regions across the world

The names of regions will be like (us-east-1, us-east-2, ap-south-1)

Region is considered as collection of data centers

Most of the aws services are region scoped

AWS Availability zones

Each region has multiple availability zones (min - 3, max - 6)

availability zones naming convention will be (ap-southeast-2a, ap-southeast-2b, sp-southeast-2c)

Each availability zone is one or more discrete data centers with different power, networking and connectivity

They are seperate from each other which makes the best choice in case of disasters

They are connected with high bandwidth and ultra low latency

AWS Data centers

AWS Edge locations

To deliver content to end users with lower latency, Amazon CloudFront uses a global network of 450+ Points of Presence and 13 regional edge caches in 90+ cities across 48+ countries

AWS Console

The AWS console is a web-based interface that allows users to interact with and manage their AWS resources.

It provides access to a wide range of services, such as computing power, storage, databases, and more.

With the console, users can create, configure, and monitor resources, as well as access tools and documentation to help them use the services effectively.

It is a user-friendly and graphical way to interact with AWS services and perform tasks such as creating and managing instances, storage, and other services.

AWS has global service like:

Identity & Access Management (IAM), Route 53 (DNS Service), CloudFront (content delivery network), WAF (Web application protocol)

Most of the Aws services are region scoped:

EC2 (Iaas)

Elastic Beanstalk (PaaS)

Lambda (FaaS)

Rekognition (SaaS)

AWS Console will look something like as shown in below picture.

`Conclusion: 🤷‍♂️`

Amazon Web Services (AWS) is a collection of remote computing services (also called web services) that make up a cloud computing platform, offered by Amazon.com.

They provide a variety of services such as storage, networking, database, and application services that help organizations move faster, lower IT costs, and scale applications.

The history of AWS can be traced back to 2002, when Amazon began offering IT infrastructure services to businesses, such as online storage and computing power, through its Amazon Web Services (AWS) division.

In 2006, Amazon introduced its Elastic Compute Cloud (EC2), which allowed users to rent virtual computers on which to run their own computer applications.

By 2011, AWS had evolved into a robust collection of services, and Amazon started to market it as a platform for building, deploying, and managing applications in the cloud.

The AWS console is a web-based interface that allows users to interact with and manage their AWS resources.

It provides access to a wide range of services, such as computing power, storage, databases, and more.

With the console, users can create, configure, and monitor resources, as well as access tools and documentation to help them use the services effectively.

It is a user-friendly and graphical way to interact with AWS services and perform tasks such as creating and managing instances, storage, and other services.

✋🏼🌩️ AWS - Cloud computing: Pt.1

First question first... 👋

What is cloud computing ☁️ ??

Cloud computing is a way of using technology to access data, services, and resources over the internet, rather than having them stored on your own computer or device. This allows for greater flexibility and scalability, as well as the ability to access your files and programs from anywhere with an internet connection.

Is Cloud computing a new term 🫣?

Cloud computing is not a new term

We use cloud computing in our daily life as well.

Take example of Gmail & Google photos that we use. We don't store the data of Gmail in our phone. It is stored somewhere far from us which exactly matches with our cloud computing definition.

Deployment models in cloud 👨‍🔬

In simple words, deployment models in cloud computing refer to the different ways in which an organization can use cloud services, whether it's publicly, privately or a combination of both.

There are three main types of cloud deployment models: public, private, and hybrid.

Public cloud: refers to cloud services that are made available to the general public over the internet. These services are owned and operated by a third-party cloud service provider like (AWS, GCP, Azure).

Private cloud: refers to cloud services that are used exclusively by a single organization. These services can be operated by the organization itself or by a third-party cloud service provider.

Hybrid cloud: refers to a combination of both public and private cloud services. This allows an organization to use the best of both worlds by taking advantage of the cost savings of public cloud services and the security and control of private cloud services.

Types of Cloud computing 👨‍🔧

There are three main types of cloud computing: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Infrastructure as a Service (IaaS) is a type of cloud computing that provides virtualized computing resources over the internet. This includes virtual machines, storage, and networking. With IaaS, customers can rent computing resources on-demand, without having to invest in physical infrastructure.

Platform as a Service (PaaS) is a type of cloud computing that provides a platform for customers to develop, run, and manage their own applications. PaaS providers typically handle the underlying infrastructure, such as servers and storage, while customers are responsible for developing, deploying, and maintaining their own applications.

Software as a Service (SaaS) is a type of cloud computing that provides customers with access to software applications over the internet. With SaaS, customers can use software without having to install it on their own computers, and can access their data and applications from any device with an internet connection.

In simple words, IaaS is like renting computer hardware, PaaS is like renting a platform to build software, SaaS is like renting software on demand, all over the internet.

Features of cloud computing 🧞‍♂️

Users can provision resources without any external human interaction

Broad network access available over the network

Multiple customers can share the same infrastructure

Quickly and easily scale on demand

Users can pay for what they used for

Reduced total cost of ownership and operational expense

Stop spending money on maintaining and owning data centers

`Conclusion: 🤷‍♂️`

cloud computing is a way of using technology to access data, services, and resources over the internet, rather than having them stored on your own computer or device.

This allows for greater flexibility and scalability, as well as the ability to access your files and programs from anywhere with an internet connection.

With different types of cloud computing like IaaS, PaaS, SaaS and different deployment models, public, private and hybrid, organizations can choose the best fit for their needs.

`Did you know 🤔 ??`

Do you know cloud computing before ?

What are the top cloud service providers ?

What is the pricing model of Cloud Computing?

Does IAM has global scope ?

What does PaaS means in simple words ?
