<h2>Service Discovery</h2>
|
|
<p>
|
|
Consul makes it simple for services to register themselves and to
|
|
discover other services via a DNS or HTTP interface. Register external
|
|
services such as SaaS providers as well.

|
|
<h2>Failure Detection</h2>
|
|
<p>
|
|
Pairing service discovery with health checking prevents routing
|
|
requests to unhealthy hosts and enables services to easily provide
|
|
circuit breakers.

<h2>Multi Datacenter</h2>
|
|
<p>
|
|
Consul scales to multiple datacenters out of the box with no
|
|
complicated configuration. Look up services in other datacenters, or
|
|
keep the request local.

<h2>KV Storage</h2>
|
|
<p>
|
|
Flexible key/value store for dynamic configuration, feature flagging,
|
|
coordination, leader election and more. Long poll for near-instant
|
|
notification of configuration changes.

<h2>DNS Query Interface</h2>
