It was a little less than 2 years ago when I did my first Windows Small Business Server 2008 migration. Time rolls on, and I shouldn't be surprised that we have now heard the first rumblings of the next new thing, complete with a code name, SBS 7.
This will be the successor to the current "less than 75 seats" small business server. The 50-300 seat Essential Business Server has already been scrapped.
They also announced a new product SBS Aurora, similar in concept to small business server, but designed to be smaller and simpler with "cloud services" integration built in for additional services. Presumably these will be services such as Hosted Exchange.
I think there is a lot to be said for that approach in certain small businesses. Exchange can be quite resource intensive, and beside adding and deleting user mailboxes, is generally not really something that ordinary users in a small business can manage themselves.
Neither of these are available yet, not even in beta. Microsoft said nothing of the sort, but if I do the counting on my fingers, I think this announcement means we can look for the products to hit the street in late 2012.
