== Discovery Plugins

Discovery plugins extend Elasticsearch by adding new discovery mechanisms that
can be used instead of {ref}/modules-discovery-zen.html[Zen Discovery].

==== Core discovery plugins

The core discovery plugins are:

<<discovery-ec2,EC2 discovery>>::

The EC2 discovery plugin uses the https://github.com/aws/aws-sdk-java[AWS API] for unicast discovery.

<<discovery-azure-classic,Azure Classic discovery>>::

The Azure Classic discovery plugin uses the Azure Classic API for unicast discovery.

<<discovery-gce,GCE discovery>>::

The Google Compute Engine discovery plugin uses the GCE API for unicast discovery.

<<discovery-file,File-based discovery>>::

The File-based discovery plugin allows providing the unicast hosts list through a dynamically updatable file.
