help Elastic FAQ
What is the relationship between Elastic and Elasticsearch?
Elastic is the company and product platform, while Elasticsearch is its distributed search and analytics engine. The broader Elastic Stack also includes Kibana for exploration and visualization, plus data-ingestion and agent tooling.
Can Elasticsearch replace a normal relational database?
It excels at full-text search, log analytics, and fast aggregation, but it is not a drop-in replacement for PostgreSQL or MySQL transaction semantics. Many systems keep authoritative records in a relational database and index searchable copies in Elasticsearch.
How is Elastic Observability different from Datadog?
Both cover logs, metrics, traces, and application monitoring, but Elastic centers those workflows on Elasticsearch and Kibana. Datadog provides a more fully managed, tightly integrated SaaS experience, while Elastic offers both hosted and self-managed deployment choices.
Is Elasticsearch still open source?
Elastic changed Elasticsearch's licensing in 2021, which led Amazon to help create the OpenSearch fork. Elastic later added AGPL as an option for portions of the free source code, but individual features and distributions still need license-specific review.
