|
Consul Connect provides service-to-service connection authorization and
|
|
|
|
|
encryption using mutual Transport Layer Security (TLS). Applications can use
|
|
|
|
|
[sidecar proxies](/docs/connect/proxies.html) in a service mesh configuration to
|
2020-01-22 00:27:43 +00:00
|
|
|
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.html)
|
|
|
|
|
for optimal performance and security. Connect can help you secure your services and provide data
|
|
|
|
|
about service-to-service
|
2019-06-14 05:52:50 +00:00
|
|
|
communications.

## 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.html). 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
|
|
|
|
|

2019-08-01 17:57:26 +00:00
|
|
|
One of the key benefits of Consul Connect is the uniform and consistent view it can
|
2019-06-14 05:52:50 +00:00
|
|
|
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
|
2020-01-14 22:59:27 +00:00
|
|
|
applications can also send open tracing data through Envoy.

## Getting Started With Connect
|
|
|
|
|
|
|
|
|
|
There are several ways to try Connect in different environments.
|
|
|
|
|
|
2019-06-14 05:52:50 +00:00
|
|
|
- The [Connect introduction guide](https://learn.hashicorp.com/consul/getting-started/connect)
|
|
|
|
|
is a simple walk through of connecting two services on your local machine
|
|
|
|
|
using only Consul Connect, and configuring your first intention.

|
|
|
|
2019-06-14 05:52:50 +00:00
|
|
|
- The [Envoy guide](https://learn.hashicorp.com/consul/developer-segmentation/connect-envoy)
|
|
|
|
|
walks through using Envoy as a proxy. It uses Docker to run components
|
|
|
|
|
locally without installing anything else.

- The [Kubernetes guide](https://learn.hashicorp.com/consul/getting-started-k8s/minikube)
|
2019-08-01 17:57:26 +00:00
|
|
|
walks you through configuring Consul Connect in Kubernetes using the Helm
|
2019-11-04 20:17:28 +00:00
|
|
|
chart, and using intentions. You can run the guide on Minikube or an existing
|
|
|
|
|
Kubernetes cluster.

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.
