What is Virtual Machine Migration

Chapter 20
Handbook of Research on Securing Cloud-Based Databases with Biometric Applications
The crucial feature for advanced elastic infrastructure capabilities in the fly of virtual machines is called Virtual machine migration. It enables a virtual machine running on one physical machine to be suspended and transported to or accessed from another physical machine where it resumes execution from exactly the same state. Migrating a virtual machine involves capturing and copying the entire state of the machine at a snapshot in time including processor and memory state as well as virtual hardware resources such as BIOS, devices networks and MAC address. It also includes the entire disk space, including system and used directories as well as swap space used for virtual memory operating system scheduling. Different type of Virtual Machine Migration includes memory migration, file system migration, network migration, device migration and security in migration ( Sharath, 2009 ).

Abstract
Cloud computing has many issues related to privacy, security, scalability, elasticity, and efficiency. Load balancing is one of the vexing issues in cloud computing. Load balancing ensures that all processors in the system have approximately an equal amount of work at any instance of time. In this chapter, the authors analyze some load-balancing algorithms and compare their performances using cloud analyst. Lots of references are added for the benefit of readers.
