MANA GEMENT STRATEGIES F O R THE CL OUD R EV OL UTION



                 by itself, but when microprocessors are combined into four-,
                 six-, or eight-CPU servers, and thousands of these servers are
                 clustered together in a cloud data center, they represent a new
                 type of computing resource, one that combines an ability to
                 deliver either standard or high performance at prices that
                 reflect low-cost parts. These individual microprocessors are re-

                 ferred to as x86 chips, and they are produced on a scale that
                 dwarfs the output of any of the high-end processors used in
                 IBM mainframes or large Unix servers.
                     It’s possible to build a large computer or computer clus-
                 ter without using x86 parts. For instance, HP’s Superdome
                 and Sun Microsystems’ UltraSPARC 10000 Starfire use high-
                 end server processors that pack more processing punch into

                 each CPU but lack the economies of scale possessed by the
                 cloud data centers built from x86 parts. But as of now, there
                 are no clouds based on high-end CPUs. It’s not in a definition
                 anywhere, but cloud computing connotes mass-produced
                 parts assembled into massive units delivering new economies
                 of scale.
                     Clouds are a form of cluster computing, and so far only a
                 small handful of companies have gained the knowledge of
                 how to build out very large clusters for general public use.

                 These companies include Amazon Web Services, Google’s
                 App Engine, Microsoft’s Azure cloud, the Rackspace Cloud,
                 Sun Microsystems (now part of Oracle), IBM, Yahoo!, eBay,
                 and Facebook. Other large Internet companies have also built
                 big data centers with x86 parts, but so far they are not available
                 to the public for on-demand, general-purpose, cloud-style
                 computing uses.
