Have you dealt with implementing and using Service Mesh in a Kubernetes environment?

Service Mesh is an infrastructure layer that manages network interactions between microservices in Kubernetes. It provides functions such as:

• Traffic management (routing, load balancing)
• Security (encryption, authentication)
• Observability (tracing, metrics, logging)

Implementation of Service Mesh usually involves installing a controller (e.g., Istio, Linkerd), which injects a sidecar proxy into pods. This allows centralized management of network policies without changing service code.

In practice, it helps improve the reliability, security, and manageability of distributed applications in Kubernetes.
