Answer: Amazon SQS, offering managed message queuing to enable decoupling and asynchronous communication between microservices.
The correct answer is D, Amazon Simple Queue Service (Amazon SQS). Amazon SQS is a fully managed message queuing service that enables decoupling and asynchronous communication between microservices. It provides reliable message delivery and ensures that messages are processed in a scalable and fault-tolerant manner. By using SQS, developers can implement a publish-subscribe pattern or a message queue pattern to enable loosely coupled communication between microservices. The other options are not designed for this purpose: A (Elastic Load Balancing) is for distributing application traffic, B (Amazon SNS) is for sending notifications to users, and C (Amazon CloudFront) is a CDN for content delivery.
