Two things

1. Cloud => Public and Private. Development in a could environment does not require you to develop off site. Currently I have two development environments one locally on this machine and a second that is a virtual server on our private cloud. This works great and was started to insure that the research I do does is isolated on a server environment that will not corrupt or otherwise destroy my local environment. It works great, and there are advantages.

2. Development in the could on a server OS better shows how the code will operate in a production environment. On the workstation I have Windows 7 and IIS etc all set and ready. I can develop web services, web applications, batch, scripts etc all locally or optionally on the virtual running the server OS. Running in the server environment allows me to monitor and determine some level of optimization in the environment the code will actually run under. This is a advantage for the most part.
