The Ambassador Design Pattern acts as a network proxy between clients and servers, encapsulating networking components like retry logic, caching, timeouts, and circuit breakers in a reusable component. It can be implemented as a library dependency within the same container or as a separate sidecar container exposing REST APIs. The pattern promotes code reusability and maintainability by centralizing network communication logic, but introduces potential latency and availability concerns when deployed as a separate service.
