Service Mesh vs API Gateway: The Only Guide You’ll Ever Need

API gateways manage external client traffic, while service meshes manage internal service-to-service traffic. Each has its own set of responsibilities, and choosing the right tool for each layer can simplify operations. Consider separating north-south traffic for API gateways and east-west traffic for service meshes. Use API gateways for external security and rate limiting, and service meshes for internal mTLS and service-to-service traffic control.
