云计算环境下实训教学平台动态迁移策略

摘要

云服务环境下最大特点是按需交付，通过虚拟化技术将相关资源构建统一调度池，并且按照用户需求为用户提供服务，因此，云服务具有并行计算、开放性以及按需交付特性。对于实训教学平台来说，在云计算环境下需要面对各种用户需求，如请求任务各种各样，实验任务类型不尽相同，设备资源存在较大差异，通过虚拟化技术来实现规范化管理何资源共享，对云资源进行调度来才能有效满足用户需求，为此，在本文中提出了云计算环境下实训教学平台动态迁移策略。策略设计了三层协同资源调度机制来实现对资源和任务管理，重点研究了任务分割、资源划分、资源调度策略等，在此基础上对系统进行仿真实验，验证云计算环境下实训教学平台动态迁移策略可行与有效性。%The biggest feature of Cloud service environment is on-demand delivery, through virtualization technology will be related to build a unified scheduling of resources, and in accordance with the needs of users to provide services, therefore, cloud service has parallel computing, open and on-demand delivery characteristics. For training teaching platform, in the cloud computing environment need to face a variety of users’ needs, such as the request of a variety of tasks, the type of experimental tasks are not same, there is a big difference between the device resources, through virtualization technology to achieve standardized management of the resource sharing, cloud resource scheduling can effectively meet the needs of users. Dynamic migration strategy is designed to achieve the management of resources and tasks in the three layers of collaborative resource scheduling mechanism. This research focuses on the task partitioning, resource allocation, resource scheduling strategy, etc., based on the design of the prototype system, the system simulation experiments, is conducted to verify the feasibility and effectiveness of the dynamic migration strategy of training platform in cloud computing environment.
