Answers
E.
Use containers that are based on Amazon Elastic Kubemetes Service (Amazon EKS) for the compute layers in the architecture.
Suggested answer: A, D

Explanation:

This solution meets the requirements because it requires the least amount of infrastructure management and guarantees exactly-once delivery for application messaging. AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. You only pay for the compute time you consume. Lambda scales automatically with the size of your workload. Amazon SQS FIFO queues are designed to ensure that messages are processed exactly once, in the exact order that they are sent. FIFO queues have high availability and deliver messages in a strict first-in, first-out order. You can use Amazon SQS to decouple and scale microservices, distributed systems, and serverless applications.Reference:AWS Lambda,Amazon SQS FIFO queues
