The Real Cloud

The real Cloud should let the application softwares do not need to care about what type and how many hardwares to execute. 

In addition to the Cloud hardware scalability, the Cloud software must be scalable too to be easy to move and dynamically allocate during runtime. 

What the goal the Real Cloud system really wants is not only a traditional client-server architecture even if the services could be moved and dynamically allocated during runtime on different servers, but also a peer to peer architecture among big and small hardwares.
