Dynamic Resource Monitoring and

Allocation in a virtualized environment

Cloud Environment

-Usage of Multiple Virtual Machines

-Resource requirement of Virtual machines differs as per the applications

-Importance of efficient resource allocation algorithms and systems is growing exponentially

After resource allocation, the run time management and monitoring of them plays a very vital role.
