General FAQ

Istio is an open platform-independent service mesh that provides traffic management, policy enforcement, and telemetry collection.

Open: Istio is being developed and maintained as open-source software. We encourage contributions and feedback from the community at-large.

Platform-independent: Istio is not targeted at any specific deployment environment. During the initial stages of development, Istio will support Kubernetes-based deployments. However, Istio is being built to enable rapid and easy adaptation to other environments.

Service mesh: Istio is designed to manage communications between microservices and applications. Without requiring changes to the underlying services, Istio provides automated baseline traffic resilience, service metrics collection, distributed tracing, traffic encryption, protocol upgrades, and advanced routing functionality for all service-to-service communication.

For more detail, please see: What is Istio?

Traditionally, much of the logic handled by Istio has been built directly into applications. Across a fleet of services, managing updates to this communications logic can be a large burden. Istio provides an infrastructure-level solution to managing service communications.

Application developers: With Istio managing how traffic flows across their services, developers can focus exclusively on business logic and iterate quickly on new features.

Service operators: Istio enables policy enforcement and mesh monitoring from a single centralized control point, independent of application evolution. As a result, operators can ensure continuous policy compliance through a simplified management plane.

We recommend following the instructions on the getting started page, which installs a demonstration configuration along with Istio’s premier sample application, Bookinfo. You can then use this setup to walk through various Istio guides that showcase intelligent routing, policy enforcement, security, telemetry, etc., in a tutorial style.

To start using Istio with production Kubernetes deployments, please refer to our deployment models documentation and the which Istio installation method should I use? FAQ page.

Istio uses the Apache License 2.0.

The Istio project was started by teams from Google and IBM in partnership with the Envoy team from Lyft. It’s been developed fully in the open on GitHub.

Istio is designed to be platform-independent, initially focused on Kubernetes. For our 1.9 release, Istio supports environments running Kubernetes (1.17, 1.18, 1.19, 1.20).

Contributions are highly welcome. We look forward to community feedback, additions, and bug reports.

The code repositories are hosted on GitHub. Please see our Contribution Guidelines to learn how to contribute.
