In multi-tenancy applications, tenants can customize and adjust the corresponding services shared by tenants based on their business requirements with strong elasticity and expansibility. As services do not exist independently, the resolving of service dependencies in practical multi-tenancy applications...
Nowadays, increasing importance has been attached to power management in modern data centers. A lot of solutions have been produced to reduce power consumption without producing an effect on quality of service. One common way is to associate with virtualization technology that has been widely used in data centers. This is due to not only its features of reliability and ease of management,but also...
Virtualization Technology has been employed increasingly widely in modern data centers in order to improve its energy efficiency. In particular, the capability of virtual machine(VM) migration brings multiple benefits for such as resources(CPU, memory, et al.) distribution, energy aware consolidation. However, the migration of virtual machines itself brings extra power consumption. For this reason,...
Today's data center often employs virtualization to allow multiple enterprise applications to share a common hosting platform in order to improve resource and space utilization. It could be a greater challenge when the shared server becomes overloaded or enforces priority of the common resource among applications in such an environment. In this paper, we propose Apad, a feedback-based resource allocation...
