Desktop on a Cloud

Greetings. I've noticed that my personal computation requirements are starting to go up quite dramatically. For example, I could practically use a separate computer just to run my IDE by itself. However the interface for such a setup with RDP would be terrible. What I need is a cloud desktop, where different windows could be running on physically separate (but most likely local lan) machines. To put it another way, I need my desktop to seemlessly integrate the computing power of a small cloud.
