A Security State Transfer Model for Virtual Machine Migration in Cloud Infrastructure
Santosh Kumar, Sunil Kumar · International Journal of Computer Applications · 2015
Virtual machine migration (VMM) is one of important services is used as a tool to facilitate system maintenance, load balancing, fault tolerance, on-demand service offerings.Live VMM transfers an active Virtual Machine (VM) from one physical host to another across different data centres.It involves a sequence of operations in iteration under a specific protocol/method for migrating execution context (active memory) and control data of a VM to the destination machine.These operations are dependent on data transfer schedule, availability of resources and overall timing constraints.The migration process is implemented by establishing shared network storage and/or a network communication channel.Along with the execution context the security configuration of the VM need to be transferred.In this paper we have proposed a security context migration framework.Both the static as well as dynamic security context is considered for migration.
