云计算中一种高效的虚拟机在线动态分配算法

Efficient Online Dynamic Allocation Algorithm of Virtual Machine in Cloud Computing

设计了一种改进的VM在线动态供应和分配算法(ODAA-VM)。只要用户发现请求或已经被分配的部分VM实例再次可用,便迅速调用ODAA-VM,确定在所要求的时期内为哪些用户分配VM实例,并保证这些用户在整个被请求期间可以持续使用这些VM。此外,该算法对用户具有激励作用,仿真实验验证了本文算法的有效性。

An improved online dynamic allocation algorithm of VM （ODAA-VM） instances was proposed. The algorithm was invoked as soon as a user places a request or some VM instances already allocated become available again, then the algorithm selects users who would be allocated VM instances for the period they requested and ensures that those users would continue using those VM for the entire period requested. In addition, the proposed algorithm has the incentive effects for the user. Simulation experiments validate the effectiveness of the proposed algorithm.
