Splunk is an American multinational corporation headquartered in San Francisco, California, which produces software for searching, monitoring, and analyzing machine-generated big data, via a web-style interface.
Splunk aims to make machine data accessible across an organization and identifies data patterns, provides metrics, diagnoses problems and provides intelligence for business operation. Splunk is a horizontal technology used for application management, security and compliance, as well as business and web analytics. Splunk has over 7,900 customers worldwide.
The company was started in 2003 by co-founders Michael Baum, Rob Das and Erik Swan. The name "Splunk" is a reference to exploring caves, as in spelunking. Splunk is based in San Francisco, with regional operations across EMEA and Asia and has over 900 employees. Splunk is venture funded, having raised 40 million USD by 2007 and became profitable in 2009. In 2012, Splunk had its initial public offering, trading under NASDAQ symbol NASDAQ: SPLK. In September 2013, the company announced the agreement to acquire Bugsense, a leading analytics solution for machine data generated by mobile devices.
Splunk's core product Splunk Enterprise (also called Splunk), can perform real-time and historical search, as well as reporting and statistical analysis. The product can index structured or unstructured textual machine-generated data. Search and analytics operations are specified using SPL (Search Processing Language), created for managing machine-generated big data. Originally based upon Unix Piping and SQL, its scope includes data searching, filtering, modification, manipulation, insertion, and deletion.
In 2011, Splunk introduced Splunk Storm, a cloud-based version of the core Splunk product. Splunk Storm offers a turnkey, managed and hosted service for machine data.
In 2013, Splunk announced a product called Hunk: Splunk Analytics for Hadoop, which supports accessing, searching, and reporting on external data sets located in Hadoop from a Splunk interface.
In 2013, Splunk announced that Splunk Storm would become a completely free service and expanded its cloud offering with Splunk Cloud.
Splunk offers its main software in two license types: an Enterprise License designed for companies and large organizations, and a gratis License designed for personal use. The freeware version is limited to 500 MB of data a day, and lacks some features of the Enterprise license edition.
As of the release of Splunk Cloud, Splunk Storm is free and includes 20GB of data storage.
