What type of queuing system is Amazon SQS?
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 FIFO queues are designed to guarantee that messages are processed exactly once, in the exact order that they are sent.
What is SQS delay queue?
Delay queues let you postpone the delivery of new messages to a queue for a number of seconds, for example, when your consumer application needs additional time to process messages. If you create a delay queue, any messages that you send to the queue remain invisible to consumers for the duration of the delay period.
Which SQS component is responsible for sending messages to your queue?
producer component
The producer component of your architecture is responsible for sending messages to your queue. At this point, the SQS service stores the message across a number of SQS servers for resiliency within the specified queue.
