This architecture works by leveraging AWS services to create a secure and efficient serverless application. Cognito authenticates the user and passes the request to CloudFront, which optimizes content delivery and forwards requests to the API Gateway. The API Gateway acts as the entry point for the serverless architecture within the VPC, triggering Lambda functions to execute application logic and interact with DynamoDB. DynamoDB stores and retrieves application data in response to these Lambda function calls.

The philosophy behind this serverless architecture is to create a secure, efficient, and scalable application that abstracts away the complexity of infrastructure management, allowing developers to focus on writing code and delivering business value.The serverless nature of the architecture aligns with modern development practices, empowering teams to rapidly iterate and deploy new features without the burden of managing underlying infrastructure.
