Concurrency is the property of a server to handle multiple simultaneous requests or tasks (in parallel). This means that the server can work on several operations at the same time, without waiting for each one to finish before starting the next.
Concurrency improves the server's throughput, which is especially useful under heavy load. To achieve concurrency, various techniques can be used, such as multithreading, process forking, or event-driven architectures.
Example of concurrency
Suppose you are running an online store and you have a web server that processes requests from customers. Imagine that several users are opening your site and placing orders at the same time. Without concurrency, the server processes requests sequentially: it takes a request from the first client, processes it, and then moves on to the next. If one request takes a long time (for example, loading a large amount of data), other clients will have to wait to receive a response.
However, with the use of concurrency, the server can handle multiple requests simultaneously. For example, when one client requests to view products, another client can request a search. The server can execute both requests at the same time, providing a quick response to both.
Thus, this technique helps improve server performance and enhance user experience by ensuring quick request processing even under heavy load. But keep in mind that implementing this technique requires time and resources.
