Research On Virtual Machine Dynamic Migaration Faced Cloud Computing

Cloud computing the origins of the first from the Internet to speak about, The rapiddevelopment of Internet bred the cloud computing to appear, Cloud computing is the largecomputer to the client/server after another a change, Cloud computing experience the parallelcomputation, distributed computing, grid computing, network storage, virtualizationtechnology development, Cloud computing is gradually becoming the future of computingtechnology development an important direction.Cloud computing architecture into infrastructure layer, the platform layer, the applicationlayer and management. Virtualization technology can cloud computing center will all thehardware pooling resources and realize the unification of the massive resources management,scalability is good.The infrastructure layer is located in the bottom of cloud architecture, It is a cloudcomputing center the foundation and the core, No matter what the cloud services providemust have the floor, The platform layer and the application layer all need to rely on it,Thispaper will focus on research behind infrastructure layer, which provides the service IaaS anduse it the key technology of server virtualization.In cloud computing, a server virtualization involving management function has theresources to reserve, resources monitoring, resources distribution, dynamic load balancing,etc.The load balance is the center of the cloud computing, an important problem, Becausecloud computing center server numerous,Customer service for resources and the dynamicchanges in demand,Customer service for resources and the dynamic changes in demand, so toensure that the user service quality, load balance is very important.The current load balanceare found in the administrator server resources close to full load operation,The current loadbalance are found in the administrator server resources close to full load operation, or foundin violation of customer service quality (also is the server resources has beeninsufficient),Manual launch VM dynamic migration.And need human can provide adequateresources for target server receives the virtual machine to migration,Such artificial operationapparently not enough flexibility, have lag.According to the front of the cloud computing center described VM dynamic problemsfacing migration,This paper put forward to solve the above problem migration architecture,And expounds its design principles and specific design process to realize amigration architecture.In order to validate put forward and design good migration architecture,This paper, basedon the popular open source xen virtual machine software to do the experiment to analysis theprocess of dynamic migration.Experiments show that the proposed transfer structuresuccessfully completed the original design principles and requirements,Ensures migrationprocess users of service quality.
