Elastic provides open source and commercial solutions designed to search, analyze, and visualize data.
Modern distributed, scalable and highly available indexing engine, we like its json API and choice of plugins. When we want to solve problems with log monitoring we use it as a part of ELK stack (Elasticsearch, Logstash, Kibana).
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 so you can discover the expected and uncover the unexpected.
