As you can see the prices in the link above, Business Objects is delivered in the cloud by pay per use in a SaaS model in AWS, and in affordable prices that makes it easy to implement by SMEs.
Unfortunately IBM does not seem to be keen in delivering Cognos suite of tools in the cloud on a SaaS model. Nor they make it affordable for SMEs as per strict and complicated licensing models.
It looks the luxury of one time gathering of sold license revenue seems to be more attractive for the big ISV than making the tool more widely deployed and generating more NPV in a strategic view. Short term revenue targets seem to overcome long term strategic benefits. We know who wins in long term. As IBM did not lead SaaS BI In the Cloud, lets hope it at least follows others...
