Cloud computing is fundamentally changing the IT ecosystem in many ways, forcing related changes in business models. Other than customers (who are always “king” and make buying decisions), the IT ecosystem players being affected by cloud includes technology providers, independent software vendors (ISVs) and systems integrators (SIs). One of the battles being fought right now by technology providers is to develop end-to-end cloud platform stacks attractive to ISVs. IBM announced additions to their recently launched PureSystems family at Impact 2012 with more than 125 ISVs supporting this family with patterns. Although the primary focus of this cloud platform stack is on ISVs, there is also a need for SIs to adapt to these changes, especially as it relates to custom software development and maintenance capabilities.
