Service Discovery and Configuration Made Easy

Get Started Download 1.1.0

Service Discovery

HashiCorp 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.

Failure Detection

Pairing service discovery with health checking prevents routing requests to unhealthy hosts and enables services to easily provide circuit breakers.

Multi Datacenter

Consul scales to multiple datacenters out of the box with no complicated configuration. Look up services in other datacenters, or keep the request local.

KV Storage

Flexible key/value store for dynamic configuration, feature flagging, coordination, leader election and more. Long poll for near-instant notification of configuration changes.

DNS Query Interface

Look up services using Consul's built-in DNS server. Support existing infrastructure without any code change.

Key Value Storage

Consul provides a hierarchical key/value store with a simple HTTP API. Managing configuration has never been simpler.
