Review of Virtual Memory Optimization in Cloud Environment

摘要

As the development in the cloud environment, virtual technology can consolidate multiple servers and abstract the hardware resources to each virtual machine. Memory is a well-known physical hardware resource, which has various limitations because of its high cost and strong power. The size of memory in which virtual machines in the Cloud environment always changes dynamically. Therefore, a flexible virtual memory management is supposed to adopt in Cloud environment so that the system allocates memory reasonably. In this paper, we observe the memory management system in Cloud environment and review the present situation of memory management.
