Istio is an open platform that provides a uniform way to connect, manage, and secure microservices. Istio supports managing traffic flows between microservices, enforcing access policies, and aggregating telemetry data, all without requiring changes to the microservice code. This chart bootstraps a Istio deployment on a Kubernetes cluster using the Helm package manager.

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:
Istio provides a number of key capabilities uniformly across a network of services:
Istio’s easy rules configuration and traffic routing lets you control the flow of traffic and API calls between services. Istio simplifies configuration of service-level properties like circuit breakers, timeouts, and retries, and makes it a breeze to set up important tasks like A/B testing, canary rollouts, and staged rollouts with percentage-based traffic splits.
With better visibility into your traffic, and out-of-box failure recovery features, you can catch issues before they cause problems, making calls more reliable, and your network more robust – no matter what conditions you face.
Istio’s security capabilities free developers to focus on security at the application level. Istio provides the underlying secure communication channel, and manages authentication, authorization, and encryption of service communication at scale. With Istio, service communications are secured by default, letting you enforce policies consistently across diverse protocols and runtimes – all with little or no application changes.
While Istio is platform independent, using it with Kubernetes (or infrastructure) network policies, the benefits are even greater, including the ability to secure pod-to-pod or service-to-service communication at the network and application layers.
Istio’s robust tracing, monitoring, and logging give you deep insights into your service mesh deployment. Gain a real understanding of how service performance impacts things upstream and downstream with Istio’s monitoring features, while its custom dashboards provide visibility into the performance of all your services and let you see how that performance is affecting your other processes.
Istio’s Mixer component is responsible for policy controls and telemetry collection. It provides backend abstraction and intermediation, insulating the rest of Istio from the implementation details of individual infrastructure backends, and giving operators fine-grained control over all interactions between the mesh and infrastructure backends.
All these features let you more effectively set, monitor, and enforce SLOs on services. Of course, the bottom line is that you can detect and fix issues quickly and efficiently.
Istio is platform-independent and designed to run in a variety of environments, including those spanning Cloud, on-premise, Kubernetes, Mesos, and more. You can deploy Istio on Kubernetes, or on Nomad with Consul. Istio currently supports:
The policy enforcement component of Istio can be extended and customized to integrate with existing solutions for ACLs, logging, monitoring, quotas, auditing, and more.
