Virtual Memory Optimization Techniques in Cloud Computing

Use of computer resources and sharing of contents has changed the ways along with as the cloud computing comes. One of the important concept of cloud computing is virtualization that plays a vital role to maximize resource usage among large number of users. To efficiently utilize the resources in a virtualized environment; they need to be over committed. Over commitment is the process of allocating more resources to a virtual machine that is physically present on the host. It is based on the principle that the majority of the Virtual Machines will use only a small percentage of the resources allocated to them at a given time. With the virtualization it becomes possible to use all different resources in shared manner and at same time by different time. There are lots of techniques now days are available to make the cloud system to be work more efficiently. This paper performs study of different changes and techniques for memory optimization and management.
