Server virtualization for enterprises and an application
MetadataShow full item record
The popularity of virtualization has increased considerably during the past few decades. One claim that virtualization is not a brand new technology. It is known that the concept of virtualization has its origins in the mainframe days in the late 1960s and early 1970s, when IBM invested a lot of time and effort and, of course money, in developing robust time-sharing solutions. The best way to improve resource utilization, and at the same time to simplify data center management was seen as virtualization during those years. Data centers today use virtualization techniques to make abstraction of the physical hardware, create large aggregated pools of logical resources consisting of CPUs, memory, disks, file storage, applications and networking. In this thesis, going over available references, a life cycle for server virtualization is proposed. Later, the steps of this life cycle were applied on a fictitious enterprise information system for security reasons. As an extension of the study, cloud computing has been planned and summarized in the Summary and Conclusions chapter.
