Platform as a Services of Amazon (AWS PaaS Offerings)

PaaS services in AWS let developers focus on writing code and building applications, while AWS handles the infrastructure, runtime, scaling, and monitoring. These services are ideal for teams who want to deploy applications quickly without managing servers.

1. AWS Elastic Beanstalk – Easy App Deployment

A fully managed platform that lets you deploy web applications and services written in Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker.

Key Features: 

• Automatically handles provisioning, load balancing, scaling, and monitoring. 
• Provides full control if you need to tweak the infrastructure.0
•  You just upload your code, and Beanstalk does the rest.

Use Cases: Web applications REST APIs Backend services

Example: Upload your Node.js code and Beanstalk deploys it with an auto-scaled environment behind a load balancer.

2. AWS App Runner – Containerized App Deployment

A fully managed PaaS service to build and run containerized web apps and APIs directly from source code or container image repositories (like GitHub or Amazon ECR).

Key Features: 

• No infrastructure management 
• Automatically handles deployment, networking, and autoscaling 
• Ideal for container-based microservices

Use Cases: Microservices Container-based REST APIs

Example: Connect App Runner to your GitHub repo and automatically deploy your app as a container.

3. AWS Lambda (PaaS for Functions) – Serverless Functions

A serverless compute service where you deploy functions as code. While primarily considered FaaS, it overlaps with PaaS in abstracting infrastructure.

Key Features: 

• Run code in response to triggers (e.g., HTTP requests, S3 uploads) 
• No server management 
• Auto-scaling and high availability built-in

Use Cases: 

• Event-driven functions 
• Backend logic for mobile/web apps

Example: Write a Lambda function that sends a welcome email when a new user signs up.

4. AWS Lightsail – Simplified PaaS for Small Apps

An easy-to-use platform that provides preconfigured virtual servers (instances), databases, and networking. It includes everything needed to launch a small app or website.

Key Features: 

• Fixed pricing plans 
• Prebuilt application stacks (WordPress, LAMP, MEAN, etc.) 
• Simplified deployment with minimal setup

Use Cases: 

• Personal websites 
• Small business applications 
• Prototyping and learning

Example: Use Lightsail to spin up a WordPress blog with one click.

5. Amazon API Gateway – PaaS for APIs

A fully managed service to create, publish, secure, and monitor APIs at any scale.

Key Features: 

• No infrastructure management 
• Supports REST, WebSocket, and HTTP APIs 
• Seamlessly integrates with Lambda, ECS, and other backend services

Use Cases: 

• Backend for mobile/web apps 
• Microservice routing 
• API monetization

Example: Use API Gateway to expose a set of Lambda functions as a public API.

6. AWS Amplify – PaaS for Fullstack Web and Mobile Apps

A development platform for building full-stack mobile and web apps with features like hosting, authentication, GraphQL/REST APIs, and data storage.

Key Features: 

• Integrates with React, Angular, Vue, iOS, Android, and Flutter CI/CD for frontend and backend 
• Backend powered by AWS services like Lambda, DynamoDB, Cognito

Use Cases: 

• JAMstack apps Serverless web apps 
• Rapid frontend/backend prototyping

Example: Deploy a React app with Amplify and add user authentication in minutes using Amplify Auth.
