About Elastic
Elastic turned its search engine into a platform: Elasticsearch for full-text and vector search, Kibana for exploration, plus observability and SIEM products on the same index. Its vector database chops made it newly relevant for AI retrieval. Cluster operations demand expertise, which is why Elastic Cloud earns its keep, and license history still colors open-source debates.
