General agreement about what SaaS is (and isn’t)

I love it when people come around to my way of thinking.

The unreasonablemen – after much discussion, deliberation and consultation, just posted that in fact they concur with my viewpoint that SaaS needs to be in the clouds (but that how far into the clouds can be debated).

Their defining feature list of SaaS;

• The application sits in some sort of cloud – normally the internet, but can be a private cloud
• It is multi-tenanted
• It requires no / minimal onsite configuration
• Bills on some sort of user pays or subscription model.

I’m not sure I entirely agree with the billing part though – Google apps is SaaS (and I guess advertising revenue kind of constitutes user pays – in a round about way).

Nice to have you on board unreasonablemen!
