Example Concept: A service mesh, such as Istio or Linkerd, introduces a dedicated infrastructure layer that handles service-to-service communication. It provides features like traffic routing, load balancing, service discovery, and failure recovery. Additionally, service meshes offer observability through metrics, logs, and traces, and enhance security with mutual TLS for encrypted communication between services. This abstraction simplifies microservices management and improves the overall resilience and performance of cloud-native applications.
