The Proxy Pattern is a structural design pattern used to control access to resources by acting as an intermediary or placeholder. It can implement restrictions like access control, caching, or logging. In the context of concurrency, the proxy ensures that only a limited number of clients access a resource at a time. For example, a proxy server can manage a pool of database connections, granting access to clients based on availability. This pattern reduces resource contention and improves system scalability and security. By isolating the resource, the Proxy Pattern adds flexibility and control over its usage.
