Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 814 discussion

This question is a trap because A is definitely the answer for a Least overhead (ECS + SQS) and in a real life scenario could be good in 99% of cases. However SQS do not implement AMQP (SQS is only a simple queueing system very basic) so we have to use Amazon MQ. In terms of containers EKS will always be a better solution than a manual setup of Docker. Good solution would have been ECS+AmazonMQ not given here Lambda can work with containers, but since there are limitations like 15 minutes limit we can't really consider it as a good solution. So B is the least bad solution.

We were asked for the LEAST operational overhead, so the company already has a managed message broker and thats why we use Amazon MQ and they are already using Kubernetes.

AnswerB For me B is a correct solution. In question AMQP is mentioned and Amazon on his doc page about MQ is providing such information: "Amazon MQ is a managed message broker service that provides compatibility with many popular message brokers. We recommend Amazon MQ for migrating applications from existing message brokers that rely on compatibility with APIs such as JMS or protocols such as AMQP 0-9-1, AMQP 1.0, MQTT, OpenWire, and STOMP." I cannot be coincidence that documentation is mentioning about AMQP. https://docs.aws.amazon.com/amazon-mq/latest/developer-guide/welcome.html

I'd go for A. Although the ideal solution and least modification would require B, with heavy rework the application can be (most likely) adopted to ECS+SQS. As it is an AWS exam, not a vendor-agnostic SA exam, A will be the correct answer.

B because only solution with Kubernetes

Should be B
