Forrester Total Economic Impact: Migrating a Heterogeneous Database Environment to IBM DB2

with one comment

Forrester have just assessed the total economic impact of migrating a heterogeneous database environment like Oracle Database to IBM DB2. The results are quite startling. Forrester talked directly with five organizations who migrated from database vendors like Oracle to IBM DB2, and then modeled the financial implications of such a move. They determined that, for a representative organization, the payback period for such a move is 12 months and that the risk-adjusted ROI for such a move is 192% over a 3 year period. Here are the summary findings:

3-year Risk-Adjusted ROI/TCO for Moving from Vendors like Oracle to IBM DB2

The report notes that:

Incremental benefits resulting from the migration to DB2 included improvements in storage and administration, efficiency, lower operational and capital costs, and savings of reduced storage through compression.

The report goes into good detail on a breakdown of the costs and benefits for such a move. You can download the entire report at The Total Economic Impact of Migrating a Heterogeneous Database Environment to IBM DB2.

Performance Information for Oracle Exadata?

with 2 comments

It is difficult to get direct performance comparisons between Oracle Exadata and competing products. Last month, The Register published what may be such a comparison in its IBM: Our appliance servers smoke Ellison’s ‘phony baloney’ article. They include an image that compares the performance and price of the IBM Smart Analytics System with a leading competitor. The IBM Smart Analytics System is, of course, an integrated hardware/software system for data warehousing and analytics that is based on DB2. The article covers an IBM Investor Day presentation that was delivered by Steve Mills of IBM, and includes the following explanatory passage:

“We benchmark all the time,” Mills said, and he pulled out some real tests to support his point. “We have a favorite competitor who likes the color red. We like the color blue. This is real workload benchmarking, not some phony baloney made-up thing that goes in an ad. We deliver a system that is fast for what customers run.”

Here is the chart that is included in the article. The Register assert that the competitor in red is Oracle Exadata.
