Virtual machines are now widely used to support applications with virtual computation service in server clusters. Here, a virtual machine can migrate to a guest server while processes are being performed. In this paper, we discuss a virtual machine migration approach to reducing the electric energy consumption of servers. We newly propose two types of algorithms, energy-aware virtual machine selection...
In clusters of servers like cloud computing systems, computation resources like CPUs and storages are virtualized. Virtual machines are now widely used to support applications with virtual computation service on computation resources. Application processes are performed on virtual machines independently of which servers of which architectures are used. Furthermore, a virtual machine can migrate from...
Scalable and high performance server cluster systems like cloud computing systems are equipped with virtual machines to efficiently utilize server resources. On the other hand, a large amount of electric energy is consumed in a server cluster system since multiple servers consume electric energy to perform application processes on virtual machines. In order to design and implement an energy-aware...
We have to reduce the electric energy consumed by servers in a cluster in order to realize eco-society. Types of algorithms for a request process to select an energy-efficient server in a cluster of servers are proposed in our previous studies. Furthermore, algorithms for energy-efficiently migrating a process on a host server to a more energy-efficient guest server is discussed. Virtual machines...
We have to reduce the electric energy consumed by servers in a cluster. In our previous studies, types of algorithms to select an energy-efficient server for a request process are proposed. Furthermore, schemes for energy-efficiently migrating a process and replicas of a process are discussed where a process and a replica migrate on a host server to a more energy-efficient guest server in our previous...
Scalable, high performance, and fault-tolerant distributed applications are realized with virtual machines in server cluster systems. Application processes are performed on virtual machines in each server. Processing load of virtual machines to perform application processes has to be balanced in a server cluster system to satisfy the application requirements like response time. On the other hand,...
Scalable and fault-tolerant information systems like cloud systems are realized in server cluster systems. Server cluster systems are equipped with virtual machines to provide applications with scalable and fault-tolerant services. Scalable and fault-tolerant application services can be provided by balancing processing load among virtual machines to perform application processes. On the other hand,...
