Interesting perspective on the whole SaaS debate on the ZDNet Between the Lines blog in their post SaaS: Shelfware as a service?.
Basically SaaS is not a magic bullet for enterprise apps, the problems associated with large complex software can’t be magicked away just because someone else runs the software for you.
Our hosted products and SaaS products are identical, as is our deployment methodology. I’d like to think we’ve put in the design time to ensure that deploying a replacement for the paper notebook is as painless as possible. That’s the result of experience and careful design, which I hope produces the same results regardless of how it’s deployed – on premises or SaaS. That some of our customers find purchasing our products as a Service is more a matter of convenience and economic preference.
