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.
Istio is composed of these components:
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.
Istiod - The Istio control plane. It provides service discovery, configuration and certificate management. It consists of the following sub-components:
Operator - The component provides user friendly options to operate the Istio service mesh.
The Istio project is divided across a few GitHub repositories:
istio/api. This repository defines component-level APIs and common configuration formats for the Istio platform.
istio/community. This repository contains information on the Istio community, including the various documents that govern the Istio open source project.
istio/istio. This is the main code repository. It hosts Istio's core components, install artifacts, and sample programs. It includes:
We use GitHub to track all of our bugs and feature requests. Each issue we track has a variety of metadata:
Epic. An epic represents a feature area for Istio as a whole. Epics are fairly broad in scope and are basically product-level things. Each issue is ultimately part of an epic.
Milestone. Each issue is assigned a milestone. This is 0.1, 0.2, ..., or 'Nebulous Future'. The milestone indicates when we think the issue should get addressed.
Priority. Each issue has a priority which is represented by the column in the Prioritization project. Priority can be one of P0, P1, P2, or >P2. The priority indicates how important it is to address the issue within the milestone. P0 says that the milestone cannot be considered achieved if the issue isn't resolved.
