Redefining Software Platforms - How PaaS changes the games for software vendors. This is the title of an interesting report sponsored by Intuit published back in Oct '09 which is definitely worth a read.
From the report:
The rise of software as a service over the past decade has opened up new opportunities for independent software vendors to develop new applications hosted and delivered via the Web. But until recently, any ISV creating a SaaS offering has had to build its own hosting and service delivery infrastructure. That has all changed in the past two years with the rise of platform-as-a-service. PaaS is the online equivalent of conventional computing platforms, providing a ready-made infrastructure on which an ISV can rapidly build and deliver a SaaS application.
While many ISVs are understandably wary of binding their fate to that of an emerging platform provider, those who have stepped forward to become early adopters of PaaS have experienced dramatic reductions in development costs and timescales. By lowering barriers to entry and foreshortening time-to-market, PaaS supercharges SaaS, accelerating the pace of innovation and intensifying competition.The advent of PaaS will change the game for ISVs – not only those who choose to introduce SaaS offerings, but also those who remain wedded to conventionally licensed, customer-operated software products.
The emphasis above is mine because this is a very powerful and important statement and should be heeded by all software vendors. Read the report if you get some time.
