[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company has a legacy application that processes data in two parts. The second part of the process takes longer than the first, so the company has decided to rewrite the application as two microservices running on Amazon ECS that can scale independently.
How should a solutions architect integrate the microservices?

A. Implement code in microservice 1 to send data to an Amazon S3 bucket. Use S3 event notifications to invoke microservice 2.
B. Implement code in microservice 1 to publish data to an Amazon SNS topic. Implement code in microservice 2 to subscribe to this topic.
C. Implement code in microservice 1 to send data to Amazon Kinesis Data Firehose. Implement code in microservice 2 to read from Kinesis Data Firehose.
D. Implement code in microservice 1 to send data to an Amazon SQS queue. Implement code in microservice 2 to process messages from the queue.

I think it's D, would be more cost effective and fault tolerant as well as loose coupling.

I think it's D, SQS is a fully managed queuing service that enables you to decouple and scale micro-services, distributed systems and server-less applications.

Selected Answer: D

You may need to scale up with multiple consumers to parallelly process the files uploaded to S3. Since process1 is faster, second process can be given to other microservice. Also, each second process should be handled only once or retried if failed. Option D gives you that flexibility.

The correct answer is A. Implement code in microservice 1 to send data to an Amazon S3 bucket. Use S3 event notifications to invoke microservice 2. This approach involves leveraging Amazon S3 event notifications to trigger the execution of microservice 2 whenever new data is uploaded to the S3 bucket by microservice 1. This decouples the communication between the microservices and ensures asynchronous processing, making it a suitable solution for integrating the two microservices in a scalable and loosely coupled manner.
