Salesforce announced the addition of Force.com, which provides a hosted infrastructure for customers to run websites in Salesforce cloud. They're also going to provide the building blocks to integrate with business applications when everything is available in 2009.
It sounds like they're trying to add value to their offerings via the cloud hype while expanding their product reach further with Facebook and Amazon partnership.
Moving forward, Salesforce will continue to be under pressure from Oracle, SAP and especially Microsoft's new Azure, which is pretty much the same offering. Not to mention Microsoft is working hard to replace SaaS with S+S, it's amazing how Salesforce expects to pass US$1 billion in annual revenue for the first time but its profit margin remains extremely slim.
The IT value stack is getting squeezed by players of all sizes trying to reshape the changing roadmap in IT. As we continue to see acceleration in the cloud hype there is also a fundamental shift in how applications are used and delivered but until the general perception adapts to the cloud idea, I still believe in the hybrid model that will emerge as the real solution to the future of SaaS.
