    Use Cases & Benefits

    • Provides an open source service mesh to connect, secure, control, and observe microservices in distributed applications.
    • Offers a uniform, transparent layer for traffic management, security, and telemetry without requiring service code changes.
    • Use for managing service-to-service authentication and secure communication in Kubernetes-based microservice environments.
    • Use for implementing advanced traffic routing, fault injection, and resiliency features across polyglot microservices.
    • Use for aggregating telemetry data and enforcing policies to monitor and control service behavior in cloud native platforms.

    From the README

    Istio is an open source service mesh that layers transparently onto existing distributed applications. Istio’s powerful features provide a uniform and more efficient way to secure, connect, and monitor services. Istio is the path to load balancing, service-to-service authentication, and monitoring – with few or no service code changes.

    In addition, here are some other documents you may wish to read:

    You'll find many other useful documents on our Wiki.

    Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio's control plane provides an abstraction layer over the underlying cluster management platform, such as Kubernetes.

    Note: The service mesh is not an overlay network. It simplifies and enhances how microservices in an application talk to each other over the network provided by the underlying platform.

    The Istio project is divided across a few GitHub repositories:

    component-level APIs and common configuration formats for the Istio platform.

    information on the Istio community, including the various documents that govern the Istio open source project.

    core components, install artifacts, and sample programs. It includes:

    istioctl command line utility.
