Inter-correlation of resource-/flow-level visibility for APM Over OF@TEIN SDN-enabled multi-site cloud

Abstract

Cloud computing and SDN technologies have potential to bring advanced capabilities to data centers and inter-connecting networks by maximizing resources utilization. However, SDN/Cloud composition also brings monitoring and visibility challenges, for operators to diagnose p+vResources (server, network and storage), flows and cloud based applications for end-to-end performance management, because legacy tools lack adequate visibility support for such kind of dynamic environments. In this paper, by developing and integrating open source tools, we present a unified visibility solution to inter-correlate Resource-/Flow-level visibility over OF@TEIN to assist cloud-based APM (Application Performance Management). Furthermore, a verification environment has been setup, to show the feasibility of our inter-correlation approach.
