CORE DEFINITION

Placing an auxiliary service (ambassador) between the client and the remote service to handle network complexities such as connection, retries, and monitoring. The client only needs to communicate with the local ambassador.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Simplify external interfaces. In diplomacy or public relations, a dedicated spokesperson (ambassador) is established. It doesn't matter if the internal situation is chaotic, as long as the ambassador's external messaging is unified and elegant.

anchor

Anchor fast decisions

A network proxy pattern in cloud-native environments, extracting client-side network logic (retries, circuit breaking, rate limiting, encryption) into a sidecar proxy, making the business code unaware. The mechanism is that the proxy 'represents' the application in handling inbound and outbound traffic, decoupling communication from business logic.
