I will feel very confident if the vendor releases the source code of the app
under one of the OSI approved licenses. Apart from the actual benefits of
Opensource, I can also be sure that I will still be able to use the app even if
the cloud vendor goes out of business. WordPress, Wikidot, Deki Wiki, etc. are examples of
cloud based apps available as Opensource.
Well, this trend is building up and we are seeing more and more Opensource
companies offering their product as SaaS. It is a smart move by the Opensource
vendors because Gartner is predicting SaaS market to hit $14.8 billion in 2012.
The recent convert to SaaS from the Opensource world is the enterprise level
content management system ezPublish. They have partnered with a Norwegian firm,
Mamut ASA, to offer their product as a SaaS
offering. It is expected to be released soon, sometime this fall. ezPublish has
a large install base including Hitachi, US Naby, MIT, etc.
