MonArch: Monitoring and analytics in software defined infrastructures

Software-Defined Infrastructure (SDI) provides a unified framework for managing heterogeneous virtualized resources in cloud infrastructures. A key challenge in the realization of SDI is the design of the monitoring system that provides integrated monitoring and measurement functionalities at large scale. In this paper, we present the design of our monitoring system called MonArch that tackles the above challenge. Unlike existing cloud and network monitoring systems, MonArch leverages big-data analytics frameworks to provide both high scalability and unified interfaces for monitoring heterogeneous virtualized resources. The effectiveness of MonArch is demonstrated through a performance evaluation and a use case, where MonArch can reduce the overhead of performing management tasks for virtualized resources.
