In Forrester's 123-criteria evaluation of information-as-a-service (IaaS) — also known as data services — vendors, we found that IBM, Informatica, Composite Software, and Denodo Technologies led the pack because of strong data services features and capabilities such as data services modeling, real-time integration, data quality, and transformation, to support most use case scenarios. IBM, Informatica, and Composite Software have proven track records of supporting enterprisewide data services implementations. Denodo Technologies provides a broad set of data services features and capabilities and a strong delivery framework. Microsoft and Red Hat are Strong Performers; each offers a viable option, especially for customers considering a Microsoft stack or open source, respectively. Oracle no longer positions a product in the IaaS market despite having a leading IaaS product that it gained through acquiring BEA Systems in 2008.
