Infrastructure as a Service (IaaS) in cloud computing provides Infrastructure as a service for the demand of user from small instance to large instance in pay per use model. The services include like computer resource, networking and data storage. An API (Application Programming Interface) is used to access the infrastructure and a dashboard to control the server and to create and manage differ...

Virtualization is an important resource of cloud computing. Many virtualization technologies allow workload consolidation, multiple operating systems, and fault tolerance mechanisms. The number of applications moving to the cloud is increasing, and cloud computing is becoming a prominent distributed computing framework. Virtual machines provide many benefits to these applications. Thus, it is c...

Cloud computing has given the new face to the distributed field. Two main issues are discussed in this paper, (I) “the process of finding the efficient virtual machine by using the concept of load balancing algorithm”. (II) “Reallocation of the Virtual Machines” i.e. migration of the Virtual Machines when cloud provider is not available with the required Virtual Machines. We have discussed abou...

Live migration enables a running virtual machine to move between two physical hosts with no perceptible interruption in service. This allows customers to avoid costly downtimes associated with hardware maintenance and upgrades, and facilitates automated load-balancing. Consequently, it has become a critical feature of enterprise class virtual infrastructure. In the past, live migration only mov...

Virtualization is an innovation that has widely been utilized in modern data centers for cloud computing to realize energyefficient operations of servers. Virtual machine (VM) migration brings multiple benefits such as resource distribution and energy aware consolidation. Server consolidation achieves energy efficiency by enabling multiple instances of operating systems to run simultaneously on...

System level virtualization provides several advantages: (i) customization is eased since virtual machines may be based on different systems; (ii) virtual machines are isolated from hardware, subsequently applications are isolated via the virtual machines; (iii) basic fault tolerance mechanisms – pro-active fault tolerance through virtual machine migration and virtual machine snapshot/restore; ...

For the purpose of load balancing, migration of VM instances or processes in cloud environment is quite useful. However, the live migration of VM is insecure. There is necessity of incorporating encryption and authentication mechanisms during migration process. An attempt is made to secure live migration of virtual machine and running processes from one machine to another. In this system, the v...

In recent years we have witnessed the rapid advent of cloud computing, in which the remote software is delivered as a service and accessed by users using a thin client over the Internet. In particular, the traditional desktop application can execute in the remote virtual machines without re-architecture providing a personal desktop experience to users through remote display technologies. Howeve...

Virtual services on computation resources like CPUs and storages are supported to applications by using virtual machines in server clusters. Virtual machines with application processes can migrate from host servers to guest servers. In this paper, we discuss a process migration approach to reducing total electric energy consumption of servers by taking advantage of virtual machines in a cluster...

-Energy consumption has been a main concern to the environment as the scale of cloud data centers become larger due to the ease of internet usage, storage and processing on cloud. As a consequence of establishment of large number of data centers, the energy consumption grows rapidly. Also they contribute in the energy consumed worldwide and consequently to the environmental drawbacks like carbo...
