Service: Amazon Simple Queue Service (SQS)
Answer:
Amazon Simple Queue Service (SQS) provides two types of queues: Standard and FIFO queues.
Standard queues offer a highly scalable, distributed queue system that allows you to decouple and scale microservices, distributed systems, and serverless applications. Standard queues provide at-least-once delivery guarantee, which means that a message in the queue is delivered at least once. It supports both message ordering and deduplication.
FIFO queues offer first-in-first-out (FIFO) delivery, which ensures that messages are delivered in the order they are sent and that each message is delivered exactly once. FIFO queues are designed to support messaging scenarios that require strict message ordering or messaging scenarios that require exactly-once processing.
In general, if message ordering and deduplication are not a concern, standard queues can be used. If strict message ordering is required, or if messages cannot be processed twice, then FIFO queues should be used.
