This white paper from Citrix examines the growth of branch offices that need full IT capabilities as employees are dispersed. The trend is to centralize the servers at headquarters while focusing on improving wide area networks (WANs) for access. As WAN performance increases, more applications and desktop functions can be run remotely. However, large files may be staged on local servers. Eventually, no IT staff will be needed at branch offices and policies will be centralized. With centralized IT, some services can easily be outsourced via cloud computing.
