A recent report concludes IBM® PureData™ System for Analytics (PDA) has distinct advantages over a comparable Teradata Data Warehouse appliance. The International Technology Group (ITG) determined the three year cost of ownership of Teradata’s 2750 as 150% more expensive than IBM’s PDA N200x. ITG surveyed 17 Teradata and 21 IBM customers, and matched their production data warehouses by workload, system size, and industry. As an example, both Teradata and IBM customers in this study were categorized into Telecom, Digital Media, Financial Services, and Retail industry sectors. ITG then further built their survey profiles based on data volumes, number of users, and workload similarities within each industry category—thus promoting reasonable comparisons based on real world observations. Starting with bottom line cost-of-ownership, the initial system expenditures for each customer industry profile were in the same ball park. That means that IBM’s PDA lower cost advantages were found in deployment, support, and personnel costs over the systems’ life time. For the application deployment area, IBM’s PDA delivered the lion’s share of their applications in 20 days or less. As the chart below shows and by stark contrast, none of the Teradata customers deployed as quickly, with the Teradata average deployment being more than three months. 1
Getting an analytics application deployed months earlier speaks to time-to-value, and attaining more business objectives. The simpler to use IBM® PureData™ System for Analytics appliance proved to be less expensive to operate because of fewer full time employees managing the system. The Teradata Data Warehouse appliance requires more administration training to understand how to achieve performance goals. For the ITG study, the 17 Teradata organizations average 1.7 full time employees to oversee the Teradata data base, as compared to less than 0.5 full time employees to tend to IBM’s PDA, on average. The primary reason for this significant gap is that IBM’s PDA end users are able to directly access their analytic appliance as a self service data warehouse. One of the ITG study participants using both Teradata and IBM’s PDA summed up the differences this way: “…we don’t have to build indexes… users write directly to the system, they don’t need to go through a DBA…we work with complete data sets instead of having everything aggregated and summarized first…we don’t have to use data models. In comparison with Teradata systems, performance-tuning overhead was said to be virtually non-existent.” 1 ITG determined that IBM customers realized additional benefits versus Teradata because of the ease in which end users deploy applications, creating “… the potential for closer business alignment than conventional data warehouse techniques.”1 In a world where vendors make significant claims of performance and total cost, it is hard to argue with real customer experience.
