Elasticsearch

Elasticsearch is a distributed search and analytics engine that developers use to index, search, and analyze data at scale. Built on REST principles, it enables applications to perform full-text search, log analysis, and real-time data processing across large datasets. The tool supports horizontal scaling for handling growing data volumes and provides reliability and ease of management. Elasticsearch is developed by Elastic and runs on multiple Linux distributions and Unix-like operating systems.

The software is written in Java and is available under the Elastic License and Server Side Public License. Elastic offers multiple deployment options including a serverless cloud service, managed cloud hosting, and self-managed installations that can run locally or on Kubernetes. The tool integrates with Kibana for data visualization and exploration, along with other components like Elastic Agent for data collection.
