Operation Changes Recommendation Method Using Histories of Operation Changes in Cloud Computing Environment

Virtualization technologies in a cloud computing system enable its users to create and delete virtual machines easily. This flexibility accelerates the update cycle of applications to keep up with user demand. When updating applications, the application management process should also be modified. If necessary changes in the management process are overlooked, this lack of changes can cause inconsistencies between an application and its management, resulting in improper system status. To identify required changes in management process, we propose a method to identify them based on an assumption that similar application updates often require similar operation changes. Evaluation results show that our method can recommend the necessary operation changes with high accuracy and can reduce the possibility of operators overlooking them about 63% of the time if operation changes are overlooked.
