Description: A request queue is a mechanism that allows managing and organizing requests that arrive at a server, keeping them waiting until they can be processed. This approach is fundamental in modern software architectures, especially in cloud development environments, where scalability and efficiency are crucial. Request queues allow decoupling the reception of requests from the actual processing, meaning a server can receive multiple requests without being overwhelmed. This is particularly useful in high-demand situations, where requests can arrive at a rate that exceeds the server’s processing capacity. Queues can implement different management policies, such as FIFO (First In, First Out), ensuring that requests are processed in the order they were received. Additionally, these queues can integrate with load balancers, which distribute requests among multiple server instances, optimizing resource usage and improving user experience. In the context of HTTP/HTTPS, request queues are essential for handling traffic spikes and ensuring that web applications remain available and responsive. In summary, request queues are a key tool in distributed system architecture, enabling efficient and scalable management of interactions between users and servers.
