What is Teradata?
Teradata is a petabyte-scale, highly customizable MPP database solution. In existence for over 30 years, Teradata has an extremely mature feature set that caters to the most demanding requirements of some of the largest organizations in the world. Its shared-nothing architecture makes Teradata a powerful database capable of linear scalability.
While Teradata has traditionally been installed on-premises with proprietary hardware, Teradata has recently begun offering its database technology as a managed service in AWS or in their own private cloud.
