Istio makes it easy to create a network of deployed services with load balancing, service-to-service authentication, monitoring, and more, without any changes in service code. You add Istio support to services by deploying a special sidecar proxy throughout your environment that intercepts all network communication between microservices, then configure and manage Istio using its control plane functionality, which includes:
Automatic load balancing for HTTP, gRPC, WebSocket, and TCP traffic.
Fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection.
A pluggable policy layer and configuration API supporting access controls, rate limits and quotas.
Automatic metrics, logs, and traces for all traffic within a cluster, including cluster ingress and egress.
Secure service-to-service communication in a cluster with strong identity-based authentication and authorization.
Istio is designed for extensibility and meets diverse deployment needs.
