At many enterprises, branch offices account for 20 percent of a company’s IT infrastructure, according to Forrester Research. Since IT departments are seeking to cut costs, branch office IT investments likely will be shifted to remote services provided by some sort of cloud computing infrastructure.
The potential impact on the service provider business is not so clear, but one might assume there will be greater bandwidth requirements at remote locations and in the backbone than presently is the case, as the traditional trade-off in computing is between local processing and bandwidth. One can compute locally, substituting cycles for bandwidth, or compute remotely, substituting bandwidth for cycles.
