Abstract: 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.

Keywords: cloud systems, live migration, resource allocation.
