Service Mesh managing microservice traffic, security, and observability out-of-band
IN 10 SECONDS
A dedicated infrastructure layer that controls how services talk to each other. Instead of writing custom security, logging, and retry logic inside every single microservice codebase, you attach a tiny helper proxy next to each service to handle all communication.
GOTCHA Intermediary proxies add latency and consume memory. If you have deep microservice chains (A -> B -> C -> D), the proxy overhead can stack up quickly.
HOW TRAFFIC PASSES THROUGH A MESH
01 Service A sends a standard HTTP request to Service B.
02 Proxy A intercepts the outbound call, encrypts it, and adds tracing headers.
03 Proxy B receives the encrypted call, validates Service A's identity, decrypts it, and hands it to Service B.
04 Control Plane coordinates all the proxies, updating routing rules and collecting metrics.
