While this was once all done with a more direct approach through software and physical connection, even our computers are beginning to be more spread out. As the computers and people become more spread out these traditional WANs are becoming less practical and more awkward than they are worth. It is no longer possible to solve our networking problems through brute force. There is simply no way to create enough power to throw at the network traffic problems and traffic problems are large and complex enough to require require creative solutions. Keeping information moving through the cloud has become more effective in every way than our old method of attacking the problem by throwing more power at it. Cloud WANs use the combined power of an entire network of computers, increasing both the overall power of the network as well as giving the network more flexibility in how it can allocate resources and information.
