Context-Aware qos assurance for smart grid big data processing with elastic cloud resource reconfiguration

Abstract

Smart grid is one of the most important area for big data applications, while the cloud-based platform is believed to be the deserved paradigm to conduct smart grid big data processing. Hence, elastic resource reconfiguration is a critical issue for smart grid big data application, since the widespread of data sources make the workload changing frequently. In this paper, we focus on the problem of context-aware QoS assurance for electric power application via elastic cloud resource reconfiguration, especially using the VM migration method. We present a framework of dynamical resource reconfiguration that characterize the major components needed for the QoS assurance during elastic resource reconfiguration. We take VM migration as the special concern, and discuss the major issues during VM migration procedure, and propose a VM migration mechanism for QoS assurance for application.
