Teradata's main competitors are other high-end solutions from vendors such as Oracle, IBM, and Sybase IQ
which is based on a massively parallel/shared nothing architecture. Recent competition has arisen from data warehouse appliance vendors such as Netezza[14] (IBM is set to acquire Netezza[15]), DATAllegro (acquired in August 2008 by Microsoft), Aster Data Systems (Teradata bought an 11 % stake in Aster Data Systems in September 2010, and agreed to pay additional $263m to take a full ownership in March 2011[16]), ParAccel, Greenplum (acquired in July 2010 by EMC), and Vertica Systems (acquired in Feb 2011 by HP), and from packaged data warehouse applications such as SAP and Kalido. These have slowed Teradata's penetration into the mid-market and some verticals, particularly energy. Kickfire, once a competitor, was acquired by Teradata in August 2010.
