Elastic is the commercial vendor that sits behind the Elasticsearch, Kibana, Logstash and Beats open source projects. Elasticsearch was created back in 2010 by Shay Banon, co-founder and CTO of the Elastic company, and is built upon the Apache Lucene information retrieval project. All of the different projects focus on taking structured and unstructured data and delivering search, logging and analytics on top of it.
Since that time, its commercial products—Elastic Stack, X-Pack and Elastic Cloud—have seen over 70 million cumulative downloads.
Elastic has been smart about making strategic acquisitions. It acquired visualization vendor Kibana, and a year or so ago it acquired Norwegian company Found, which was commercializing Elasticsearch and offering it as a service on top of Amazon Web Services. This strategy appears to have worked, and it is interesting to look at the graph below that tracks the relative exposure of Elasticsearch and one of the competitive offerings, Splunk.
