At present, there is a lot of interest in clouds, or shared infrastructures. With the rise of energy costs, the cost of floor space, and the lack of local IT support skills, it is evident that many IT departments are looking to consolidate and virtualize their servers, use remote cloud services for new applications, or simply host seasonal projects that would normally require acquiring new servers. To address these issues, customers use different virtualizations solutions that are available on the market, like XEN hypervisors, AIX PowerVM, and Solaris Zones. Each has its strengths and limitations. Although VMware is the market leader in terms of server virtualization, VMware still has some challenges with Oracle.
