Elasticsearch is a hugely popular service that provides an incredible search-engine and analytics tool powered by a powerful schema-free document database.
It provides a scalable, highly available, and lightning-fast search engine. The database itself is distributed across nodes, which can be further split into shards — which are by default replicated to protect against data loss.
Alongside Logstash, Kibana, and Beats — we produce a world-class data collection, transformation, analytics, and visualization platform.
Together these are known as the Elastic (or ELK) stack — and are a powerful tool for anyone working with data. Elasticsearch is the heart of the stack.
