What is the primary function of Amazon Simple Queue Service (SQS)?

The primary function of Amazon Simple Queue Service (SQS) is to facilitate message queuing. SQS is a fully managed message queuing service that enables decoupling of the components of a cloud application, ensuring that messages between different parts of the system can be transmitted and processed asynchronously. This allows applications to communicate reliably at scale and helps improve the overall resilience and availability of distributed systems.

By using SQS, developers can send, store, and receive messages between services without losing messages. This is particularly useful in microservices architectures where different services need to communicate with each other while remaining independent. The use of message queues helps in managing workloads more efficiently, handling spikes in traffic, and ensuring that components can run without being tightly coupled, which enhances system reliability.

The other choices describe functions unrelated to Amazon SQS, focusing instead on machine learning integration or virtual reality, which are not within the scope of message queuing services.
