Istio Fundamentals

Istio Fundamentals

Istio enables organizations to secure, connect, and monitor microservices, so they can modernize their enterprise apps more swiftly and securely. Istio manages traffic flows between services, enforces access policies, and aggregates telemetry data, all without requiring changes to application code.

Istio has two components: the data plane and the control plane. The data plane is the communication between services.
