Your company has set up an application in AWS. The application has been developed in-house which consists of many distributed components. You would need a new service to deliver and manage messages for the distributed system. Which of the following services should you suggest?

Answer options:

A.Suggest the usage of the SQS service for the messaging across the distributed components.
B.Suggest the usage of the SNS service for the messaging across the distributed components.
C.Suggest the use of CloudWatch logs to deliver and manage the messages.
D.Suggest the use of CloudTrail logs to forward and manage the logs.

Answer – A
The AWS Documentation mentions the following.
Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message oriented middleware and empowers developers to focus on differentiating work. Using SQS, you can send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available. Get started with SQS in minutes using the AWS console, Command Line Interface or SDK of your choice, and three simple commands.
Option B is invalid since this is used to send notifications to different endpoints.
Options C and D are invalid because either CloudWatch or CloudTrail is not a messaging system and cannot deliver or manage messages.
