I am looking at signing up for the Cloud Sites service from Rackspace, but I looking for practical experience anyone has had with their ASP.NET 4 'beta' program. I plan to develop in MVC3 moving forward and cannot consider the Cloud Sites service if ASP.NET 4 doesn't work well / correctly on their platform. Has anyone tried hosting an ASP.NET 4 / MVC 3 site on Cloud Sites? What was your experience like?
I've had Rackspace Cloud Sites for nearly a year now and it works very well for most client sites. However, I'm very disappointed that it has taken so long for them to support .Net 4.0, and forget about it if you want to use anything requiring anything above medium trust. I haven't found a single document database that will work yet, and when I've asked their support about this, the general answer they like to give is, "Upgrade to a Cloud Server". It's almost like they give you the bare minimum in the Sites option and then when something isn't supported they upsell you.
It doesn't sound like it but overall I'm pleased with most of their service. The .Net 4.0 Beta isn't bad -- I haven't had any issues with it and I have two sites on it. Just wish they'd open up their service a little and give us some real capabilities.
