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. | ||

|
||
## Introduction | ||
|
||
[Istio](https://istio.io/latest/docs/concepts/what-is-istio/) is an open platform for providing a uniform way to [integrate | ||
microservices](https://istio.io/latest/docs/examples/microservices-istio/), manage [traffic flow](https://istio.io/latest/docs/concepts/traffic-management/) 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: | ||
|
||
- **Envoy** - Sidecar proxies per microservice to handle ingress/egress traffic | ||
between services in the cluster and from a service to external | ||
services. The proxies form a _secure microservice mesh_ providing a rich | ||
set of functions like discovery, rich layer-7 routing, circuit breakers, | ||
policy enforcement and telemetry recording/reporting | ||
functions. | ||
|
||
> 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: | ||
|
||
- **Pilot** - Responsible for configuring the proxies at runtime. | ||
|
||
- **Citadel** - Responsible for certificate issuance and rotation. | ||
|
||
- **Galley** - Responsible for validating, ingesting, aggregating, transforming and distributing config within Istio. | ||
|
||
- **Operator** - The component provides user friendly options to operate the Istio service mesh. | ||
|
||
## Repositories | ||
|
||
The Istio project is divided across a few GitHub repositories: | ||
|
||
- [istio/api](https://github.com/istio/api). This repository defines | ||
component-level APIs and common configuration formats for the Istio platform. | ||
|
||
- [istio/community](https://github.com/istio/community). This repository contains | ||
information on the Istio community, including the various documents that govern | ||
the Istio open source project. | ||
|
||
- [istio/istio](README.md). This is the main code repository. It hosts Istio's | ||
core components, install artifacts, and sample programs. It includes: | ||
|
||
- [istioctl](istioctl/). This directory contains code for the | ||
[_istioctl_](https://istio.io/latest/docs/reference/commands/istioctl/) command line utility. | ||
|
||
- [operator](operator/). This directory contains code for the | ||
[Istio Operator](https://istio.io/latest/docs/setup/install/operator/). | ||
|
||
- [pilot](pilot/). This directory | ||
contains platform-specific code to populate the | ||
[abstract service model](https://istio.io/docs/concepts/traffic-management/#pilot), dynamically reconfigure the proxies | ||
when the application topology changes, as well as translate | ||
[routing rules](https://istio.io/latest/docs/reference/config/networking/) into proxy specific configuration. | ||
|
||
- [security](security/). This directory contains [security](https://istio.io/latest/docs/concepts/security/) related code, | ||
including Citadel (acting as Certificate Authority), citadel agent, etc. | ||
|
||
- [istio/proxy](https://github.com/istio/proxy). The Istio proxy contains | ||
extensions to the [Envoy proxy](https://github.com/envoyproxy/envoy) (in the form of | ||
Envoy filters) that support authentication, authorization, and telemetry collection. | ||
|
||
## Issue management | ||
|
||
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](https://github.com/orgs/istio/projects/6) 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. | ||
