and aggregate telemetry data. Istio's control plane provides an abstraction
layer over the underlying cluster management platform, such as Kubernetes.

Istio is composed of these components:

- **Envoy** - Sidecar proxies per microservice to handle ingress/egress traffic
   between services in the cluster and from a service to external
   services. The proxies form a _secure microservice mesh_ providing a rich
