Determining cloud platform limits on resource migration

This article discusses the different types of virtual machine migration between computing resources, their logical and physical limitations. For live migration, such memory migration methods as pre-copy and post-copy, their temporary differences are considered. Chapter 2 discusses the work in which the requirements for physical and logical constraints. In chapter 2.1 for the post-copy method, the algorithm for working at the hypervisor level is described. For the pre-copy and post-copy methods a comparison of time indicators was made. Chapter 2.2 describes the physical constraints for virtual environments, which should be taken into account when drawing up a service level agreement. Logical restrictions on the migration of virtual machines are described in chapter 2.3, which should be taken into account when building a resource allocation strategy in the cloud. In conclusion, it is noted that constraints must be considered when developing resource allocation strategies.
