Method and system for dynamically adjusting virtual machine memory in cloud computing environment

Abstract

The invention discloses a method and system for dynamically adjusting the memory of a virtual machine in a cloud computing environment. The method includes: formulating a memory dynamic adjustment strategy; Usage amount; judging step, judging whether the memory usage amount is greater than the upper limit threshold in the memory dynamic adjustment strategy or less than the lower limit threshold value in the memory dynamic adjustment strategy; dynamic adjustment step, if the memory usage amount is greater than the upper limit threshold value, then for the virtual machine The memory is dynamically increased; if the memory usage is less than the lower threshold, the memory of the virtual machine is dynamically reduced. The present invention can effectively expand or reduce the memory of the virtual machine dynamically without shutting down the virtual machine through the cloud management platform, which ensures that the core business running in the virtual machine can run continuously without interruption, and reduces unnecessary memory waste.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and system for dynamically adjusting memory of a virtual machine in a cloud computing environment. Background technique [0002] With the rapid development of today's computers and networks, virtualization technology is constantly improving. With the continuous development of virtualization technology and the continuous use of cloud computing, the gap in performance between systems and applications running on virtual machines and systems and applications running on actual physical machines is decreasing, making more and more enterprises will key business Running on a virtual machine on a cloud computing virtualization server. Therefore, how to ensure the uninterrupted and continuous operation of the key business running on the virtual machine is a concern nowadays. [0003] In the existing cloud computing environment, the administrator can only specify a fixe...

Problems solved by technology

[0004] Therefore, when the memory size allocated by the administrator to the virtual machine cannot meet the needs of the application, the administrator must re-adjust the memory usage of the virtual machine after shutting down the virtual machine, so that the user's application must be stopped for a period of time. Critical business cannot continue to operate

Moreover, if the administrator allocates too much memory to the virtual machine, and the application of the virtual machine sometimes does not need to use so much memory, this will inevitably cause a waste of resources
