| Abstract: | The virtualization technology has provided the important guarantee for the dynamic deployment and security isolation of the infrastructure as a service(IaaS) in the cloud computing.It is a challenging problem to optimize,across time,the distribution of RAM among a maximal set of virtual machines by reclaiming memory from ones that have an excess of memory and providing it to others that need more memory.This paper proposes a memory optimization scheme for multiple virtual machines with the cooperation of sp... |
