computing resources to be shared among multiple performance-isolated platforms called virtual machines. This will allow data center operators to maintain the desired performance while achieving higher server utilization and energy efficiency. For the server part‚ we implement dynamic management algorithm (DMA). From this‚ Virtual Machines are ordered according to their migration costs within each Physical Machine. For application part‚ we adopt cloud computing concept to implement applications providing

physical servers by creating a virtual environment to accomplish the same task instead of using many individual servers. Currently‚ each server has their own set of tasks or programs to run and none of them intersects with each other‚ which can lead to some servers being underutilized while others are idle because no request are sent to the servers. Creating a virtual machine (VM) can reduce the physical network load by shifting network traffic to the internal virtual net. For example‚ the receptionist

as a platform for the virtual servers’ operating systems. The hypervisor keeps each virtual server completely independent and unaware of the other virtual servers running on the physical machine. Each guest server runs on its own OS -- even have one guest running on Linux and another on Windows. The hypervisor monitors the physical server’s resources. As virtual servers run applications‚ the hypervisor relays resources from the physical machine to the appropriate virtual server. Hypervisors have

Because of this they are looking into a new found technology which is virtualization. Virtualization is not a new concept. It has been around since the main frame computer systems. What is virtualization? It is defined as “the creation of a virtual (rather than actual) version of something‚ such as an operating system‚ a server‚ a storage device or network resources” (Rouse‚ Virtualization‚ 2010). Virtualization falls into three main categories: Operating System‚ Storage‚ and Applications. Because

Virtualization Virtualization is the ability to run multiple operating systems on one computer system‚ the virtual software acts as a go between for the main computer’s OS and the virtual OS(s). The primary computer‘s central processing unit (CPU)‚ random access memory (RAM)‚ hard disk drive (HDD)‚ network‚ peripherals‚ etc. is accessible by the virtual system. Virtual Software Recommendation One would suggest VirtualBox due to its efficient installation‚ simplicity in understanding
