Cloud computing is one of the hot topics of today. That's not wonder if we consider the benefits in cost, performance and availability. Looking historically it's a new wave between user and host centered computing. Thank to personal computers the balance of computing distribution has swung towards the personal computers and now on-line servers swing it back. However not every cloud has a silver lining and sometimes it's better to have you cloud solution near to you; http://www.nearcloud.com/ at least for latency reasons which can be considerable if your cloud is far away from the horizon.
However there is also a technology aspect of the near cloud. When Xerox PARC has been created the inventors used computer power in workstations which was actually available in huge computers. Thinking out of the usual performance and conventional way of use limitations they could create breakthrough products. I think the same can happen with cloud computing. It's a best laboratory of building supercomputers from loosely coupled systems while developing technologies which make this architecture "invisible" for programmers and users. What if we would put the same technology in a small box? A lot of processor chips consisting thousands of miniature computers with local memory and storage connected by a simple network connection. It would run a cloud operating system resulting in enormous power, and flexibility. What could it be used for? Controlling sophisticated home robots, doing high level data analysis...? maybe somebody at Xerox will invent a suitable application for it.
