Example Concept: A service mesh, such as Istio or Linkerd, abstracts the communication logic from microservices by deploying a network of sidecar proxies alongside each service instance. This setup allows for advanced traffic management, including load balancing, retries, and circuit breaking, as well as end-to-end encryption and authentication. Service meshes also provide rich observability features like tracing and metrics collection, facilitating easier monitoring and troubleshooting of distributed systems.
