                 what made it hard to resist was the fact that it worked in so
                 many cases. It was sufficient for much enterprise networking,
                 which was discovered as enterprises started relying on inter-
                 nal TCP/IP networks called intranets to carry traffic derived
                 from the Internet. These intranets turned out to be “good
                 enough” even when their performance lagged that of the

                 proprietary networks. And the messages got through with
                 high reliability. They might on rare occasions arrive minutes
                 or even hours later than the sender intended, when a router
                 outage led to concentrations of traffic on the nearby routers
                 drafted by many other routers as the way around the outage.
                 Instead of maintaining an expensive proprietary network
                 across the country, the company could let its internal TCP/IP

                 network originate the message, then let the Internet serve as
                 its external connection to other facilities, partners, suppliers,
                 and customers.
                     If there was still resistance to conversion, it faded at the
                 mention of the price. The Internet was free, and the TCP/IP
                 protocol used inside the company was freely available, built
                 into various versions of Unix and Linux and even Microsoft’s
                 Windows Server. When internal operation is aligned with the
                 external world operations—and the cost is the lowest avail-

                 able—the decision on what to do next becomes inevitable. A
                 similar alignment will occur between external cloud data cen-
                 ters and the internal cloud.
                     To prepare for that day, it’s important to start expanding
                 x86 administration skills and x86 virtualization skills rather
                 than sitting out this early phase of cloud computing. There
                 are immediate benefits to starting to reorient your computing
