# Consul Service Mesh
|
|
|
|
Consul Service Mesh provides service-to-service connection authorization and
|
|
encryption using mutual Transport Layer Security (TLS). Consul Connect is used interchangeably
|
|
with the name Consul Service Mesh and is what this document will use to refer to for Service Mesh functionality within Consul.
|
|
Applications can use [sidecar proxies](/docs/connect/proxies) in a service mesh configuration to
|
|
establish TLS connections for inbound and outbound connections without being aware of Connect at all.
|
|
Applications may also [natively integrate with Connect](/docs/connect/native) for optimal performance and security.
|
|
Connect can help you secure your services and provide data about service-to-service communications.
|
|
|
|
Review the video below to learn more about Consul Connect from HashiCorp's co-founder Armon.

## Application Security
|
|
|
|
Connect enables secure deployment best-practices with automatic
|
|
service-to-service encryption, and identity-based authorization.
|
|
Connect uses the registered service identity (rather than IP addresses) to
|
|
enforce access control with [intentions](/docs/connect/intentions). This
|
|
makes it easier to reason about access control and enables services to be
|
|
rescheduled by orchestrators including Kubernetes and Nomad. Intention
|
|
enforcement is network agnostic, so Connect works with physical networks, cloud
|
|
networks, software-defined networks, cross-cloud, and more.
|
|
|
|
## Observability
|
|
|
|
One of the key benefits of Consul Connect is the uniform and consistent view it can
|
|
provide of all the services on your network, irrespective of their different
|
|
programming languages and frameworks. When you configure Consul Connect to use
|
|
sidecar proxies, those proxies "see" all service-to-service traffic and can
|
|
collect data about it. Consul Connect can configure Envoy proxies to collect
|
|
layer 7 metrics and export them to tools like Prometheus. Correctly instrumented
|
|
applications can also send open tracing data through Envoy.

## Getting Started With Consul Service Mesh
|
|
|
|
There are several ways to try Connect in different environments.
|
|
|
|
- The [Getting Started with Consul Service Mesh collection](https://learn.hashicorp.com/tutorials/consul/service-mesh?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS)
|
|
walks you through installing Consul as service mesh for Kubernetes using the Helm
|
|
chart, deploying services in the service mesh, and using intentions to secure service
|
|
communications.
|
|
|
|
- The [Getting Started With Consul Service Mesh for Kubernetes](https://learn.hashicorp.com/tutorials/consul/service-mesh-deploy?in=consul/gs-consul-service-mesh?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS) guide walks you through installing Consul on Kubernetes to set up a service mesh for establishing communication between Kubernetes services.
|
|
|
|
- The [Secure Service-to-Service Communication tutorial](https://learn.hashicorp.com/tutorials/consul/service-mesh-with-envoy-proxy?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS)
|
|
is a simple walk through of connecting two services on your local machine
|
|
using Consul Connect's built-in proxy and configuring your first intention. The guide also includes an introduction to
|
|
using Envoy as the Connect sidecar proxy.
|
|
|
|
- The [Kubernetes tutorial](https://learn.hashicorp.com/tutorials/consul/kubernetes-minikube?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS)
|
|
walks you through configuring Consul Connect in Kubernetes using the Helm
|
|
chart, and using intentions. You can run the guide on Minikube or an existing
|
|
Kubernetes cluster.
|
|
|
|
- The [observability tutorial](https://learn.hashicorp.com/tutorials/consul/kubernetes-layer7-observability?utm_source=WEBSITE&utm_medium=WEB_IO&utm_offer=ARTICLE_PAGE&utm_content=DOCS)
|
|
shows how to deploy a basic metrics collection and visualization pipeline on
|
|
a Minikube or Kubernetes cluster using the official Helm charts for Consul,
|
|
Prometheus, and Grafana.
