Maintaining knowledge of infrastructure has always been a key element to ensure the performance of complex distributed systems, being the first step to control quality of service, identify key performance bottlenecks, or make decisions about resource allocation and job scheduling, to name a few. In cloud-native edge boxes, edge computing leverages cloud-native applications to process/analyze some of their computing/storage own close to the location where the data is generated by a large number of heterogeneous devices. Some of the differences between this approach and more conventional architecture, like cloud are that in a distributed environment, these resources/applications have varying running conditions depending on resource availability, quality of network connection, and being geo-distributed. These aforementioned challenges in operations, however, contribute to a requirement toward identifying efficient methods for monitoring operational environment with continuity in order to maintain and sustain services. In this article, we present setup and configuration of distributed resources with cloud-native edge capabilities and having centralized connectivity in a specialized multi-site cloud testbed. Second, we propose a solution to persistently maintain multi-view (ie, resource-layer and flow layer) visibility data (monitoring) collection under varying situations and environments. Third, we present verification results on a prototype implementation and interactive visualization support. This solution allows maintaining monitoring visibility data that conform to the specific demands of cloud-native edge computing resources. We evaluate the research by maintaining visibility data of multi-site cloud at 14 research institutes for several months and we demonstrate that it fulfills the requirements we previously enumerated. INTRODUCTIONMaintaining a stable monitoring state has been a key element in ensuring the sustainable performance of complex distributed systems, as the first step in managing quality of service, detect failures, or making decisions about resource allocation, to name a few. Edge cloud 1 is a broad distribution of storage/-compute resources around geographic locations with cloud-like capabilities located at the infrastructure edge. Cloud-native application is a methodology of building

One key challenge in operating virtualized Future Internet testbed is how to monitor various experiments running on the top of it. Among multiple visibility levels for resources, flows, and services, flow-centric visibility is becoming crucial. In this paper, in order to monitor lifecycle experiments over OF@TEIN OpenFlow-based SDN testbed, we are working on flow-centric visibility. The main idea behind flow-centric visibility is duplicating specific packets from OpenFlow-enabled switches and redirecting those packets via a visibility fabric. The duplicated and redirected packets are processed to provide basic visualization about flow information. The flow tapping, implemented for the virtual switches of OF@TEIN SmartX Boxes, is preliminary verified by utilizing it to monitor the targeted lifecycle experiments.

Modern information communication technologies (ICT) infrastructures are getting complicated to cope with the various demands needed to accommodate the emerging technology paradigms such as cloud, software-defined networking (SDN), and internet of things (IoT). Visibility is essential for the effective operation of such modern ICT infrastructures to easily pinpoint server faults, network bottlenecks, and application performance troubles. Even though many conventional monitoring solutions are now available, multi-layer visibility is still limited when operating such complicated infrastructures. To address this particular limitation, a futuristic multi-layer visibility framework denoted as SmartX multi-view visibility framework (MVF), is proposed for unifying the visibility of underlay, physical and virtual resources, flow, and workload layers. To unify multi-layer visibility, this paper presents a comprehensive extension of SmartX MVF with flow-centric visibility for simultaneously monitoring physical-virtual resources, flows classification, and visualization to eventually assist secured operation of SDN-enabled multisite cloud infrastructure. Flow-centric visibility design has five main components (1) a lightweight network packets-precise flows visibility collection component, (2) a visibility data aggregation and tagging component, (3) a multi-layer visibility data integration component, (4) a non-learning-based network packets flows classification component, and (5) a visualization component. Furthermore, a prototype implementation of SmartX MVF with flow-centric visibility is deployed in an SDN-enabled multisite cloud playground to verify the proposed multi-view visibility of fine-grained flow-aware physical-virtual resources.
