# EC2 Discovery plugin
The EC2 discovery plugin provides a list of seed addresses to the [discovery process](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2653/deploy-manage/distributed-architecture/discovery-cluster-formation/discovery-hosts-providers) by querying the [AWS API](https://github.com/aws/aws-sdk-java) for a list of EC2 instances matching certain criteria determined by the [plugin settings](https://www.elastic.co/elastic/docs-builder/docs/2653/reference/elasticsearch/plugins/discovery-ec2-usage).
