help Elastic Stack FAQ
What is the difference between the Elastic Stack and the ELK Stack?
The Elastic Stack is the modern evolution of the ELK Stack, adding lightweight data shippers called Beats to the original Elasticsearch, Logstash, and Kibana suite. Elastic N.V. rebranded it to reflect this broader suite of observability and security tooling.
What is the role of Beats in the Elastic Stack?
Beats are lightweight data shippers installed on servers to send operational data directly to Elasticsearch or through Logstash. They capture metrics, logs, and network data without requiring heavy resource consumption on the host machine.
How does Elasticsearch store and retrieve data so quickly?
Elasticsearch is a distributed search and analytics engine that stores data in inverted indices. This architecture allows it to perform near real-time full-text searches and complex aggregations across massive datasets.
Who develops and maintains the Elastic Stack?
The Elastic Stack is developed and maintained by Elastic N.V., the company behind Elasticsearch. They offer the stack as a managed cloud service as well as an open-source or free-to-use self-hosted download.
