[All AWS Certified Solutions Architect - Professional Questions]

A solutions architect is evaluating the reliability of a recently migrated application running on AWS. The front end is hosted on Amazon S3 and accelerated by
Amazon CloudFront. The application layer is running in a stateless Docker container on an Amazon EC2 On-Demand Instance with an Elastic IP address. The storage layer is a MongoDB database running on an EC2 Reserved Instance in the same Availability Zone as the application layer.
Which combination of steps should the solutions architect take to eliminate single points of failure with minimal application code changes? (Choose two.)

A. Create a REST API in Amazon API Gateway and use AWS Lambda functions as the application layer
B. Create an Application Load Balancer and migrate the Docker container to AWS Fargate
C. Migrate the storage layer to Amazon DynamoDB
D. Migrate the storage layer to Amazon DocumentDB (with MongoDB compatibility)
E. Create an Application Load Balancer and move the storage layer to an EC2 Auto Scaling group

Given that Lambda now supports containers and it specifically says the containers are stateless, option A also seems good.

On paper - yes. But if you’d really try to convert a regular web app to a lambda compatible image - you’d see that this option still far away from “little code changes” :)
