Splunk

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 (the product) captures, indexes and correlates real-time data in a searchable repository from which it can generate graphs, reports, alerts, dashboards and visualizations.
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.[1] 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.

Big Data Storage Tools

Hadoop, Netezza, AsterData
Netezza (pronounced Ne-Tease-Ah) designs and markets high-performance data warehouse appliances and advanced analytics applications for uses including enterprise data warehousing, business intelligence, predictive analytics and business continuity planning.
Founded in 1999 by Foster Hinshaw, Netezza was purchased by IBM in 2010 for $1.7 billion. Netezza and Hinshaw are credited with creating the data warehouse appliance category to address consumer analytics efficiently by providing a modular, scalable, easy-to-manage database system that’s cost effective. This class of machine is necessary to manage the "data-intense" workloads of modern analytics and discovery that are not well handled with legacy technologies, most of which are designed around traditional "computer-centric" workloads.
Netezza's implementation is characterized by (a) data-intelligent shared-nothing architecture, where the entire query is executed on the nodes with emphasis on minimizing data movement; (b) use of commodity FPGA's to augment the CPU's and minimize network bus traffic; and (c) embedded analytics at the storage level.
Netezza is based in Marlborough, Massachusetts, with 19 offices in more than 12 countries, including the UK, Japan, China and Germany. As of August 2010, Netezza had a workforce of 469 employees.[1] The company opened a new development lab in Cambridge, Massachusetts in August 2010.
Netezza is widely[citation needed] credited for either inventing or bringing renewed attention to the data warehouse appliance category, depending upon whether one regards long-time data warehouse technology vendor Teradata as having been in the data warehouse appliance category all along.
Aster Data Systems is a data management and analysis software company headquartered in San Carlos, California. It was founded in 2005 and acquired by Teradata in 2011.
