Policy Management Technique Using Blockchain for Cloud VM Migration

In recent years, the use of the cloud has become one of the essential elements when constructing a system for deploying web services. By combining serverless cloud services, various web services can be performed without building servers. However, serverless environments have various limitations, and traditional methods of building servers on VM are indispensable. In addition, technology for migrating VM to physically different hosts was established, and it became possible to easily migrate VM between hosts under the same cloud management. However, depending on the server running on VM, there may be restrictions on the range that can be physically moved. We have solved the problem by focusing on the problem that migration can be performed without checking the information about the server running on the VM at the time of migration. Therefore, in this paper, we introduce a managing technique for VM migration policy in the cloud using blockchain, and show that it is more useful than the conventional policy management method.
