Tell about your experience working with Service Mesh technologies and their implementation in infrastructure.

A Service Mesh is an infrastructure layer that manages communication between microservices in a distributed system. In my experience, I have implemented Service Mesh (e.g., Istio) to improve security, observability, and traffic management in Kubernetes clusters.

The main steps of implementation included:

• Installing and configuring the Service Mesh controller.
• Injecting sidecar proxies (Envoy) into pods to intercept network traffic.
• Setting up routing rules, load balancing, and security policies (mTLS).
• Integrating monitoring and tracing (Prometheus, Jaeger) through Service Mesh capabilities.

This approach increased fault tolerance, simplified version management, and ensured secure interactions without changing application code.
