Elasticsearch is a distributed, RESTful search and analytics engine from Elastic. Together with Kibana it underpins three solution areas: search, observability (including log analytics and infrastructure monitoring) and security (including SIEM and endpoint security). Organisations use it for search features in applications, for searching company data and for analysing logs. You can run it yourself, locally or on Kubernetes, or use Elastic Cloud in a serverless or hosted form. Elastic Cloud is also sold through the AWS, Azure and Google Cloud marketplaces.
Elastic N.V. is a Dutch-American company, founded in Amsterdam in 2012 and listed on the New York Stock Exchange. Elastic Cloud runs on AWS, Google Cloud and Azure, with European regions such as Frankfurt, Ireland, the Netherlands and Paris, so the underlying infrastructure belongs to US providers. Elasticsearch is available under ELv2 and SSPL; in 2024 Elastic announced that it was adding the AGPL as an open-source licence. Self-hosting gives a European organisation full control over location and keys.
