The Tubes are atwitter with discussion of the news from PDC this week, not least of which was the announcement of Microsoft's new Windows Azure cloud computing platform. Details about the offering remain scant at this point -- the SDKs and developer programs are "by invitation only" -- but what I've heard so far sounds promising. I'm particularly interested in Live Services, which finally lifts the lid off the inner workings of Live Mesh (of which I am a devoted user).
But while I'm fairly rah-rah about the potential of cloud computing platforms in theory, I remain skeptical about their efficacy for enterprise software development in practice. By comparison, Microsoft is nothing if not gung-ho. Where Amazon and Google have tread carefully, unveiling their cloud services first as pilot programs with limited applications, Microsoft seems determined to deliver its version of the cloud to its entire ISV community on a plate. While the geek in me is itching to play around with this stuff, my instinct says "caution."
Let's dispense with the "Microsoft is evil" argument for the moment: Who wants to get in bed with Microsoft for something like this? Windows developers, that's who. You Microsoft ISV partners out there all recognize that a certain amount of vendor lock-in goes with the territory. It might be nice not to have to keep that revenue stream going from your accounts into Microsoft's, but for you the benefits outweigh the costs -- and the risks.
And if you think about it, who makes for a better cloud-computing partner than Microsoft? They're already expanding their datacenters, up there in Redmond, to support the new hosted platforms. That's exactly the kind of thing you want from a cloud vendor. Microsoft reaches into its deep pockets so you don't have to have deep pockets of your own. So what if your applications will be tied to Microsoft's services and APIs? For Windows developers that's true already.
I believe, however, that the kind of lock-in you get with a cloud-computing service is different than the lock-in you get with the Windows developer ecosystem as it exists today.

Server virtualization is a popular option for dealing with mounting datacenter costs. Another equally promising approach is the use of an Application Delivery Controller. Citrix NetScaler provides a low-cost way for organizations to reduce their server count and accrue cost savings from a reduction in space, cooling, power and personnel.
