Amazon Simple Queue Service (SQS)

Amazon Simple Queue Service (SQS) is a cloud-based message queuing service that helps different parts of an application communicate seamlessly. Imagine it as a digital post office: when one part of an application needs to send a message, it drops it into a queue, which acts as a holding area. Other parts of the application can then retrieve and process these messages at their own pace. This setup improves reliability, efficiency, and scalability, allowing applications to handle varying workloads without losing messages, making it easier to develop and manage distributed systems.
