How to create an SQS Queue on AWS

Amazon Simple Queue Service (SQS) is a managed message queuing service of AWS which enables us to decouple and scale microservices, distributed systems, and serverless applications. Using SQS, we can send, store, and receive messages between software components at any volume, without losing messages. Standard queues offer maximum throughput, best-effort ordering, and at least-once delivery. FIFO queues are designed to guarantee that messages are processed exactly once, in the exact order that they are sent.

SQS Eliminates administrative overhead, provides Reliably delivery of messages, keeps sensitive data secure, and scales elastically and cost-effectively.

Security, Durability, Availability, Scalability, Reliability, Customization are a few of the benefits of using SQS.

There are 2 types of SQS Queues on AWS.

1. Standard Queue
2. FIFO Queue

1. Standard Queue:
   Supports a nearly unlimited number of transactions per second (TPS) per API actionA message is delivered at least once, but occasionally more than one copy of a message is delivered. Occasionally, messages might be delivered in an order different from which they were sent.
2. FIFO Queue:
   FIFO queues support up to 3,000 messages per second (TPS), per API actionA message is delivered once and remains available until a consumer processes and deletes itThe order in which messages are sent and received is strictly preserved.
