Introduction to service mesh using Istio

A service mesh is an infrastructure layer that controls and observes the communication between services, for example, microservices. The capabilities in a service mesh, for example, observability, security, policy enforcement, resilience, and traffic management, are implemented by controlling and monitoring all internal communication inside the service mesh, that is, between the microservices in the service mesh. One of the core components in a service mesh is a lightweight proxy component that is injected into all microservices that will be part of the service mesh. All traffic in and out of a microservice is configured to go through its proxy component. The proxy components are configured in runtime by a control plane in the service mesh using API's exposed by the proxy. The control...
