Service Mesh

A service mesh is a dedicated infrastructure layer that adds features to a network between services: - Service to service communication (service discovery and encryption) - Observability (monitoring and tracking) - Resiliency (circuit breakers and retries)

Without a service mesh: each microservice implements business logic and cross cutting concerns (CCC) by itself. With a service mesh: many CCCs like traffic metrics, routing, and encryption are moved out of the microservice and into a proxy.
