how to design the architecture for hosting app on AWS

Tier 1: Web Tier

• AWS Elastic Beanstalk: You can use AWS Elastic Beanstalk to deploy and manage your web application's front-end code. Elastic Beanstalk automatically provisions and configures the necessary resources, such as EC2 instances, load balancing, and auto-scaling, making it easier to deploy and manage your web application.
• Elastic Load Balancing: Elastic Beanstalk automatically sets up an Elastic Load Balancer (ELB) to distribute incoming traffic across multiple EC2 instances. This ensures high availability and fault tolerance for your web application.

Tier 2: Application Tier

• AWS Lambda: You can use AWS Lambda to run your Python programs and business logic. Lambda functions can be triggered by events from other AWS services, such as API Gateway or S3.
• Amazon API Gateway: API Gateway can be used to create and manage APIs that your web application can call to send user information and receive results from the Lambda functions.

Tier 3: Data Tier

• Amazon S3: As mentioned earlier, you can use S3 to store user data and uploaded images securely.
• Amazon RDS or DynamoDB: If your application requires a relational database, you can use Amazon Relational Database Service (RDS) to provision and manage a database instance. Alternatively, if you need a NoSQL database, you can use Amazon DynamoDB, a fully managed NoSQL database service.
