Elasticsearch is the world’s leading open source search analytics solution with an emphasis on speed scale and relevance is transforming how the world uses data. Our solution is delivered as Elastic Stack delivered as an
appliance based on different nodes and options.

So, what is the ELK Stack? “ELK” is the acronym for three open source projects:

• Elasticsearch,
• Logstash
• Kibana.

Elasticsearch is a search and analytics engine. Logstash is a server-side data processing pipeline that ingests data from multiple sources simultaneously, transforms it, and then
sends it to a “stash” like Elasticsearch. Kibana lets users visualize data with charts and graphs in Elasticsearch. The Elastic Stack is the next evolution of the ELK Stack.
