Your server landscape may be as small as one single webserver, or composed of thousands of servers, distributed across several continents. CloudAngels can make sure your platform runs as efficiently as possible, while maintaining the lowest possible TCO using on-demand compute power.
Imagine your company gets mentioned in a media article and consequently the number of customers your web-based system has to serve is quadrupled. Will your architecture let you scale fast enough so as to not lose any one of these customers? More importantly, when the rush is gone, what will you do with your all your hardware you threw at the problem?
What do you do if your research requires your company to use a couple of thousand of machines? Wait a year until the new Server farm is built, meanwhile ignoring competition?
These are common scenarios which are addressed by cloud computing.
