I'm in a large organization and haven't thought we'd be thinking much about the cloud. Yes, I am a fan of the cloud service Yammer. It seems to fit that niche pretty well. I do worry about fremium users and those that lose governance in the area of microblogs turned rogue doc mgmt centers. On the other hand, I think it's great that there's a service where partners, vendors, and customers can all converge in a place and conversations can *really* get interesting and open dialogue can happen in a somewhat safe place.
On the other hand, in SharePoint Land, I am focused on an enterprise set of services from the Intranet, enterprise search, TFS, and a host of applications built on SharePoint. I can't imagine moving my thousands of SharePoint team sites, and definitely not my app environment and there's not way I'd think of pushing up my Intranet.
Today I was begging for some cloud. I have been dealing with some out dated Adobe Lifecycle stuff, and recently found the servers aren't running the right Java versions, the OS, is outdated, and various concerns there. My team's expertise is SharePoint, .NET, Client side scripting, AD, IIS, and SQL. There's one guy who knows Linux, and such, but we're in a bad space. I'd much rather move these forms to the cloud than host them on premise. It would allow me to provide a much higher level of service, my service levels would meet what the managed service could provide. Now I can imagine someone in my same shoes with a team of Java developers and Linux guys trying to support SharePoint. Some are trying to support a bunch of team sites, on some outdated Windows 2003 box with SharePoint 2003 or 2007. Yeah, I'd be pushing for cloud as well. It seems the cloud can help IT get focused, and provide higher levels of service where they can focus on what they really need to focus on. I think there's been a lot of hype around cloud, but there are definitely some places where it should be pushed and places where it's better left alone. I may try to push these Adobe forms into SharePoint or push them into the cloud, but either way I will feel better than simply letting it languish around without some attention.
