What is Elastic/Open Search?

Elasticsearch is a distributed, RESTful search and analytics engine capable of solving a growing number of use cases. As the heart of the Elastic Stack, it centrally stores your data for lightning fast search, fine‑tuned relevance, and powerful analytics that scale with ease. OpenSearch is an open-source, distributed search and analytics suite derived from Elasticsearch and maintained by Amazon Web Services. Both are commonly used for log analytics, full-text search, security intelligence, business analytics, and operational intelligence. They allow users to index, search, and analyze large volumes of data in near real time.
