Elasticsearch Overview
Elasticsearch is a distributed, RESTful search and analytics engine capable of addressing a growing number of use cases. It's built on top of Apache Lucene and provides near real-time search and analytics capabilities. Elasticsearch is commonly used for log analytics, full-text search, security intelligence, business analytics, and operational intelligence. It is a key component of the Elastic Stack (formerly known as the ELK Stack), which includes Elasticsearch, Logstash, and Kibana.
