The question that is often posed in one rhetorical flourish or another is this: Which is better (faster, more efficient, blah blah blah...) Java or C++?

In fact, this question is more like deciding on a business plan rather than simply selecting a tool from the tool box.

External Cloud Providers Must Be More Than Hardware Pool Providers

Cloud computing provides more than scaling. It provides elasticity. That means it can expand needed enterprise software resources and contract those resources that are not needed and It can do all this on demand.

These providers would basically sell capacity to other businesses that would otherwise have to maintain enough IT to accommodate infrequent but significant spikes in usage traffic. These cloud computing vendors would be providing what is called an external cloud. One use cas... (more)
