THE HYBRID CL OUD



                     Isn’t this just wishful thinking? What about CEOs’ con-
                 cerns about customer data traveling out to the public cloud,
                 where the IT managers lose track of it? Don’t spikes in activity
                 include customer data?
                     Yes, spikes in workloads often include sensitive data. So an
                 IT manager needs to analyze what work is appropriate to send

                 out to the cloud and what is not. He doesn’t need to send the
                 work that is causing the spike, if the data should stay in house.
                 Because the virtualized servers are being managed as a pool, if
                 the operations manager offloads some equivalent to the spike,
                 he’ll pick up the capacity he needs to continue operating.
                 This is a fresh subject for computer professionals in enterprise
                 IT, but they’re already identifying several types of workload

                 that could be shipped off to the cloud without posing much
                 of a threat to secure company operations.
                     The first such type of workload is software testing. Hardly
                 anyone in her right mind wants to steal unfinished, unproven
                 software designed for some purpose specific to a single given
                 company. The testing of the software in cloud environments
                 would involve intensive use of many servers for short periods
                 of time, almost a definition of the kind of job that the cloud is
                 good at. In addition, quality assurance of new software is a

                 closely related job that could be performed in the cloud.
                     The staging of new applications, where they’re configured
                 to run with all the other pieces of software that they depend
                 on, is a third transferable job. A new human resource man-
                 agement or new accounting application is first launched in a
                 staged environment to see if anything goes wrong. If it does,





                                                                      93
