I like asking Twitter to define or explain things for me, because I know the answers I get back are going to be quick and succinct.
If I were to ask someone to describe the difference between SaaS and on demand in an email or in person, the answers would be long and detailed. Sometimes that's good information to have. But often a 140-character limit is nice.
After reading Matthew's post about SaaS, I wondered if it was the same as on demand, or if there were clear differences. So I asked Twitter. Here are some of the responses I received:
- mjayliebs: demand is broader, SaaS is typically Software only where OD takes on broader - storage, platform, messaging (XaaS=future).
- vtri: Don't like "on-demand" but may work as a vague broad term to catch both SaaS and hosted (license owned but 3rd party hosts).
- njcwelke: i think of SaaS as on demand with a throttle control - where on demand tends to be one-size-fits-all, SaaS is more flexible
- DuaneJackson: SaaS != on demand
- DuaneJackson: IMHO, on-demand is like Pay-as-you-go - take it when you want it. SaaS isn't neccasarily easily off-and-onable
- DuaneJackson: like the difference between buying Newsweek as and when you want it or subscribing.
If you agree with any these answers, or if you would like to expand upon them or disagree with them, you're not limited to 140 characters in the comments here.
