Workflow Management Through Database Migration in Cloud Computing Environment

Abstract

Cloud computing (CC) is a new concept compared with conventional methods to information technology, in which companies and enterprises implement open cloud systems on a pay-per-use basis to minimize costs. Virtualization is a pervasively implemented strategy in modern data centers (DCs) to optimize the utilization of energy, minimize greenhouse gas emissions, and decrease operating costs. The migration of virtual machines (VM) is commonly used within and through DCs to address a range of virtualized cloud system needs. For example, server consolidation needs power management via VM migration. Load balancing, fault tolerance, network repair, and reducing the violation rate of service-level agreement (SLA) often include live VM migration. The VM migration process is very resource-intensive and involves smart solutions to prevent saturation of the network bandwidth which reduces server downtime.
