IBM 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.

On September 20, 2010 IBM announced they would acquire Netezza to become a subsidiary of IBM.

History

Netezza was founded in 1999 by Foster Hinshaw. In 2000 Jit Saxena joined Hinshaw as co-founder. The company was incorporated in Delaware on December 30, 1999 as Intelligent Data Engines, Inc. and changed its name to Netezza Corporation in November 2000. Netezza announced the industry's first "data warehouse appliance" in 2003 to meet the industry's need to make use of the rapidly increasing ability to collect consumer data. In July 2007, Netezza Corporation had its initial public offering under the ticker "NZ" on NYSE Arca.

Hinshaw coined the term "data warehouse appliance" to describe a product of shared nothing parallel nodes specifically targeted for high data volumes for modern data analytics. He left Netezza to found Dataupia in 2005.

Netezza software was based on PostgreSQL 7.2, but did not maintain compatibility.

Jim Baum was appointed CEO of Netezza in January, 2008 after co-founder Jit Saxena announced his retirement. Baum started at Netezza as chief operating officer in 2006. Prior to joining Netezza, Baum was president and CEO of Endeca in Boston for five years.

IBM and Netezza on September 20, 2010 announced they entered into a definitive agreement for IBM to acquire Netezza in a cash transaction at a price of $27 per share or at a net price of approximately $1.7 billion, after adjusting for cash.

Products

TwinFin, Netezza's primary product, is designed for rapid analysis of data volumes scaling into petabytes. The company introduced the fourth generation of the TwinFin product in August 2009. Netezza introduced a scaled-down version of this appliance under the Skimmer brand in January 2010.

In February 2010, Netezza announced that it had opened up its systems to support major programming models, including Hadoop, MapReduce, Java, C++, and Python models. Netezza's partners predicted to leverage this analytic application support are Tibco Spotfire, MicroStrategy, Pursway, DemandTec and QuantiSense.

The company also markets specialized appliances for retail, spatial, complex analytics and regulatory compliance needs. Netezza sells software-based products for migrating from Oracle Exadata and for implementing data virtualization and federation (data abstraction) schemes.

The Netezza appliance was the foundation of IBM DB2 Analytics Accelerator (IDAA).

In 2012 the products were re-branded as IBM PureData for Analytics.

Technology

Netezza's proprietary AMPP (Asymmetric Massively Parallel Processing) architecture is a two-tiered system designed to quickly handle very large queries from multiple users.

The first tier is a high-performance Linux SMP host that compiles data query tasks received from business intelligence applications, and generates query execution plans. It then divides a query into a sequence of sub-tasks, or snippets that can be executed in parallel, and distributes the snippets to the second tier for execution.

The second tier consists of one to hundreds of snippet processing blades, or S-Blades, where all the primary processing work of the appliance is executed. The S-Blades are intelligent processing nodes that make up the massively parallel processing (MPP) engine of the appliance. Each S-Blade is an independent server that contains multi-core Intel-based CPUs and Netezza's proprietary multi-engine, high-throughput FPGAs. The S-Blade is composed of a standard blade-server combined with a special Netezza Database Accelerator card that snaps alongside the blade. Each S-Blade is, in turn, connected to multiple disk drives processing multiple data streams in parallel in TwinFin or Skimmer.

AMPP employs industry-standard interfaces (SQL, ODBC, JDBC, OLE DB) and provides load times in excess of 2 TB/hour and backup/restore data rates of more than 4 TB/hour.

In 2009, the company transitioned from PowerPC processors to Intel CPUs. In August, 2009, with the introduction of the 4th generation TwinFin product, Netezza moved from proprietary blades to IBM blades.

Recognition and criticism

Netezza was added to Gartner's Magic Quadrant for DBMS in January, 2009.

Netezza was mentioned in "The Spy Files", released by the controversial whistleblower organization WikiLeaks. The file claims Netezza bought a copy of The Geospatial Toolkit, a location-based analytic software from The Intelligent Integration Systems, Inc., "allegedly reverse engineered the code and sold a hacked version to the Central Intelligence Agency for use in remotely piloted drone aircraft". It goes on to state, "IISI, which says that the software could be wrong by a distance of up to 40 feet, sued Netezza to prevent the use of this software. Company founder Rich Zimmerman stated in court that his 'reaction was one of stun, amazement that they (CIA) want to kill people with my software that doesn't work.'"
