Do you know what Service Mesh is in Kubernetes?

Service Mesh in Kubernetes is an infrastructure layer that manages communication between microservices. It provides functions such as routing, load balancing, security (e.g., traffic encryption and authentication), monitoring, and request tracing without the need to modify application code.

Typically, Service Mesh is implemented through sidecar proxies that are deployed alongside each service in a pod. Popular implementations include Istio, Linkerd, and Consul Connect.

Example: if you have multiple microservices, Service Mesh allows centralized management of access policies, collection of metrics, and logging of traffic between them, as well as automatically restarting or redirecting requests in case of failures.
