Sidecar Proxy Pattern: Decoupling Network Logic from Application Code in Microservice Mesh Architectures
Modern microservice systems rarely fail because of “business logic.” They fail at the edges: timeouts, retries that amplify load, uneven traffic distribution, certificate rotation issues, or inconsistent observability. As the service count grows, embedding these network concerns inside every application becomes expensive and error-prone. The Sidecar Proxy Pattern addresses this by moving network logic out […]
