Istio is a service mesh infrastructure that provides a centralized control plane to manage, secure, and observe communication between distributed microservices. It functions as a policy-driven network traffic controller, enabling developers to route, balance, and secure service-to-service traffic without requiring modifications to application code. The system enforces zero-trust security by utilizing mutual transport layer authentication to verify cryptographic identities for every network request. The project distinguishes itself through a sidecar-less proxy architecture, which offloads netw
Restricts network access by validating service accounts at the transport layer.
