Is Elasticsearch free? | Elasticsearch Tutorial

Elasticsearch is a free open source software.

You can run Elasticsearch on-premises, on Amazon EC2, or on Amazon Elasticsearch Service. With on-premises or Amazon EC2 deployments, you install Elasticsearch and other necessary software, provision infrastructure, and manage the cluster yourself. With Amazon Elasticsearch Service, you don’t have to worry about provisioning infrastructure or installing and maintaining Elasticsearch software. Amazon Elasticsearch Service is a fully managed service that simplifies time-consuming cluster management tasks such as software patching, failure recovery, backups, and monitoring.
