The control plane manages and coordinates the work of the sidecars through a set of central components. Overall, the service mesh is an abstract layer on top of applications to handle service-to-service communication.
In this chapter, we will understand the architecture of Istio from the perspective of the control plane to look at its features and functions. ...
