Example Concept: A service mesh, such as Istio or Linkerd, provides features like load balancing, service discovery, and failure recovery, along with advanced capabilities like circuit breaking, retries, and fault injection. It operates by deploying a sidecar proxy alongside each service instance, intercepting and managing all network traffic. This setup allows for fine-grained control over traffic policies, secure service communication through mutual TLS, and comprehensive metrics collection for monitoring and tracing.
