Amazon SQS

Amazon Simple Queue Service (SQS) is a cloud-based messaging system that enables different parts of a software application to communicate reliably. It works like a virtual mailbox where messages are stored temporarily until the recipient is ready to process them. This allows systems to send, store, and receive messages asynchronously, ensuring that tasks are decoupled and can handle varying loads without losing data. SQS is scalable, secure, and easy to use, making it ideal for building distributed applications that require dependable message passing between components.
