Performance Monitoring and Improvement by VMM in Cloud System

Shafali Gupta, Payal Kulkarni

Abstract: Cloud computing is a promising paradigm able to rationalize the use of hardware resources by means of virtualization. Virtualization allows to instantiate one or more virtual machines (VMs) on top of a single physical machine managed by a virtual machine monitor (VMM). Similarly to any other software, a VMM experiences aging and failures. It was always possible that, because of overload, non-responsive applications, bulky applications, system get slowed down or get hanged. In this case, every user who was using physical machine in virtual mode gets affected by system crash. Might be, he loses his important data, work. Also, task given to printer, scanner, CD-ROM or writer get affected resulting in loss. The paper focuses on solution of above mentioned problem. Virtual machine monitor (VMM) monitors every virtual machine. It monitors, running applications, memory usage, resources used, etc. If it comes to found any problem with any application, then VMM stops the executions such that terminate the corresponding applications. In emergency, to recall system from harmful crashes, it restarts the application. Priority is given to application termination and to save user work in limited problems and priority is given to system in case of dangerous problems.
