Cloud computing has become a part of everyone's life now. So researchers have immense interest in cloud performance and security. For security and to provide single system image so that user gets an illusion that everything is stored at his own system cloud uses concept of virtualization. For that different virtual machines (VMs) runs on same or different servers. These VMs can be migrated from one server to another. VM migration and power consumption on cloud has been a trending area of

Keywords Cloud, VM, green algorithm, NP-Hard. CLOUD ARCHITECTURE Cloud architecture consist of following elements :  Cloudlet.  Broker.  Cloud information service (CIS).  Datacenter. Cloudlet Job that are submitted on cloud are termed as cloudlet. Cloudlet has fixed capacity which is measured in terms of million instructions per second (MIPS). Broker Broker is the agent which is responsible for submitting cloudlet on cloud. It request for resources from CIS and interacts with datacenter. Cloud information service (CIS) CIS is responsible for allocating resources to cloudlet. It creates VM for handling cloudlet. These VM are also of fixed
