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.

“…To monitor distributed systems and take appropriate decisions, many researchers have concentrated on developing and using third-party open-source tools or use customized tools to log application metrics, such as Zabbix, 4 Nagios, 5 or Cacti. 6 However, Nagios is limited in terms of scalability and dependencies on third-party tools for resource monitoring.…”

“…Aligned with Future Internet testbeds like GENI (the Global Environment for Networking Innovation), in 2017, we launched, OF@TEIN+ playground (ie, SDN-enabled multisite cloud), as an open/federated playground for future networks, proposed to further enhance and expand OF@TEIN playground. [3][4][5] OF@TEIN+ multisite cloud (denoted as OF@TEIN+ Playground) connects around 14 sites located in 10 countries (ie, Korea, Malaysia, Thailand, Indonesia, Laos, Cambodia, Vietnam, Myanmar, Bhutan, and India) and interconnected via OF@TEIN+ network. OF@TEIN+ playground maintains hyper-converged box-style resources named "SmartX Micro-Box."…”

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

“…32 In comparison, OF@TEIN playground can adopt any OpenFlow-based SDN controllers. Lately, ONOS SDN controller 33 is used by playground operators, while OpenDayLight SDN controller 16 is mainly used by playground developers. The cloud functionality at OF@TEIN playground is provided through OpenStack, 15 which is not natively supporting the playground visibility and interactive visualization for multiregion cloud deployment of OF@TEIN playground.…”

SmartX Multi‐View Visibility Framework for unified monitoring of SDN‐enabled multisite clouds

Modern ICT infrastructures are getting complicated to cope with the various demands to accommodate the emerging technology paradigms such as cloud, SDN, and IoT. In these ICT infrastructures, unified monitoring is essential to easily pinpoint server faults, network bottlenecks, and application performance issues for effective operation. Although many traditional monitoring solutions are now available, unified monitoring has not kept pace, creating a big gap when operating these modern infrastructures. To address this particular limitation, in this paper, a futuristic multilayer visibility framework, denoted as SmartX Multi-View Visibility Framework (MVF), is proposed by unifying the visibility of physical and virtual resource, flow, and workload layers for timely detection and mitigation of various operational issues. Based on our experience of working with Future Internet testbeds, we first design SmartX MVF to enable visibility collection and validation from distributed MPs. Then, we link it with subsequent visibility integration capability empowered by DataLake-based visibility storage for interactive visualization of collected visibility. Furthermore, a prototype implementation of SmartX MVF is developed and deployed in OF@TEIN
