Virtualized Db Clustering and Server Consolidation: It's Implementation With a Live Case Study
Virtualization is a technology that transforms today's powerful computer hardware, which was designed to run a single operating system and a single application, to run multiple virtual machine having independent operating system. Many times, the authors observes that the server resources been underutilized. Virtualization allows one to efficiently utilize the available resources on physical machine. In virtualization environment, different virtualized machines can have different host operating system (i.e. different versions windows, Linux, Solaris etc). The most important concept to understand in virtualization is that, the virtual machines operating systems are independent from physical server operating system.
