The elastic extended system based on virtualization and strategies can provideefficient resource control, strategies control, application management and otherfunctions. It can shorten the deployment time of system and can reduce the cost ofenterprise IT system operation and maintenance. It includes the following core value:To transform enterprise IT infrastructures into private cloud platform throughvirtualization technology, and to realize flexible allocation for computing resources andstorage recources between different enterprise applications through GUI-based tool.To provide the condition and index definitions for application system and itscomponents, and to support the customized strategy of application system operationload and the processing flexibility based on rule through the extensible framework.To provide customization flexibility for system event handling, and to supportcomplex load balance and error recovery logic customization to meet the dealing withemergency of different scenarios.To reduce redundant server amounts and CPU frequency dynamically to improveenergy efficiency and reduce the maintenance costs of enterprise IT system, if enoughprocessing power and resources have been supplied to application systems.The major areas of research include resource monitoring, resource management,strategic management, flexible terms, system redundancy and disaster recoverymanagement.Resource Monitoring: a variety of networks, computing resources, and middlewareresources, real-time monitoring. These resources include CPU, memory, hard disk usage,network traffic status, database, application server request processing and so on.Resource Management: The management of the host resource pool, and hostvirtual machines under management. Host management, including adding the host,maintaining the host, remove host, shut down and restart the specified host the specifiedhost; virtual machine management, including start, stop and restart the virtual machine,virtual machine migration and import / export, generating the virtual machine snapshots.Strategic Management: Study how to define a high scalability of the policyframework, and through strategies to meet the specific business model to increase the demand for custom policy, involving conventional resources, including applications,middleware, host, virtual machine.Elastic calculation: According to the temporary situation of virtual machineresources, virtual machines to dynamically change to meet application performancerequirements.System redundancy and disaster recovery management: When a physical resourcepool crashing after a host failure, there must be other physical machine monitor crashingto the host as redundant backup automatically takes over. When the host virtual machineunder a crashing failure, the other virtual machines must be monitored and crashing thevirtual machine as a backup to automatically take over the crashing of the virtualmachine.This paper introduced an experimental prototype to verify the feasibility for theelastic extended system based on virtualization technology and strategy.
