b) To monitor application performance
c) To encrypt data stored in S3
d) To automate deployment pipelines
Answer:
a) To decouple and queue messages between distributed application components
Explanation:
Amazon SQS (Simple Queue Service) is a fully managed message queuing service that allows users to decouple and queue messages between distributed application components. SQS helps ensure that messages between microservices or distributed systems are delivered reliably and asynchronously.
With SQS, users can build fault-tolerant, decoupled architectures, where application components communicate without needing to operate in a tightly coupled manner. Messages can be queued and processed at different times, improving system resilience.
Amazon SQS supports both standard queues (for maximum throughput) and FIFO queues (for message order and exactly-once processing), making it suitable for a wide range of use cases.
