Help Test Cytanium's Site Cloud
Go get a free Site Cloud test account and check it out. You can upload content using WebMatrix or Visual Studio... or deploy any of the Web Application Gallery applications directly from the control panel. Set up multiple sites. Set up multiple instances (web workers*) per site. Hit it with some load and let us know how the experience goes.
*What's a "web worker"? It is an additional instance of your site running on a different server. So, one enabled web worker is just like standard shared web hosting. Two or more enabled web workers turns the hosting plan into a highly-available load-balanced site solution. Two web workers handles two times the load! Three web workers handles three times the load!
Seriously, it's very cool, check it out now. We want as much testing and feedback as possible. When this product matures and is ready for release its going to be awesome and your feedback along the testing cycle will help further assure its awesomeness! :)
