Simple Queue Service

Amazon Simple Queue Service (SQS) is a fully managed message queuing service that allows you to integrate queuing functionality in your application. SQS offers two types of message queues: standard and FIFO.

Features

  • send messages
  • store messages
  • receive messages

Tips

  • The Simple Queue Service (SQS) is found under the Application Integration on the AWS Management Console.
  • FIFO queues support up to 300 messages per second.
  • FIFO queues guarantee the ordering of messages.
  • Standard queues offer best-effort ordering but no guarantees.
  • Standard queues deliver a message at least once, but occasionally more than one copy of a message is delivered.

What are the benefits of a FIFO queue over a standard queue? Pick two.
SOLUTION:
  • messages are processed exactly once
  • messages are processed in exact order
