Abstract:

Business process collaboration between independent parties is challenging when participants do not completely trust each other. Tracking actions and enforcing the activity authorizations of participants via blockchain-hosted smart contracts is an emerging solution to this lack of trust, with most state-of-the-art approaches generating the orchestrating smart contract logic from Business Process Model and Notation (BPMN) models. However, compared to centralized business process orchestration services, smart contract state typically leaks potentially sensitive information about the state of the collaboration, limiting the applicability of decentralized process orchestration. This paper presents a novel, collaboration confidentiality-preserving approach where the process orchestrator smart contract only stores encrypted and hashed process states and validates participant actions against a BPMN model using zero-knowledge proofs. We cover a subset of BPMN, which is sufficient from the practical point of view, support messagepassing between participants, and provide an open-source, endto-end prototype implementation that automatically generates the key software artifacts.

Abstract:

A web service composition is considered as a real revolution in SOA (Service Oriented Architecture). It is based on assembling independent and loosely coupled services to build a composed web service. This composition can be described from both a local or a global perspective by respective orchestration or choreography. The validation of web service orchestrations is the main topic of this work. It is based on the verification of two classes of properties: generic and specific properties. The former can be checked for any invoked web services whereas the specific properties are different interdependence relationships between activities within an orchestration process. These properties cannot be directly verified on the orchestration process, so, the authors have to use formal techniques. In this paper, they propose a formal approach for the validation of web service orchestrations. This work adopts WS-BPEL 2.0 as the language to describe the web service orchestration and uses the SPIN model-checker for the verification engine. The WS-BPEL specification is translated into Promela code which is the input language for the SPIN model-checker, in order to check generic and specific properties expressed with LTL (Linear Temporal Logic).

Abstract:

If nineteenth-century aesthetics distinguish between distinct, colourful French instrumentation and doubled, equalised German orchestration, this distinction softens when the ‘New German’ orchestration of Wagner and Strauss exploits individual instrumental colours before dissolving them into massive orchestral sonorities. Similarly, if early French electroacoustic music counteracts the meta-serialism of early twentieth-century German electronic music, Pierre Schaeffer's Traité des objets musicaux combines his early anecdotal Noise Studies with a noise-reduction process into a new, rather German aesthetic of electroacoustics. In search of musical objects through a reductive, analytical listening (entendre), Schaeffer's neutralisation of anecdotal noises into musical objects is analogous to New German orchestration's neutralisation of individual orchestral colours in order to synthesise new orchestral combinations. Although this orchestral synthesis is different from the analytical probe for new valeurs involved in entendre, the separation of the noise from its residual signification are fundamental processes within both nineteenth-century orchestrational and twentieth-century electroacoustic musical aesthetics. If our current understanding of electronic music aligns Schaeffer and Pierre Henry wholly with modernity and its putatively radical and self-conscious break with Berlioz, Brahms and historical tradition, this article suggests that an essential underlying continuity in the French-instrumentation/German-orchestration binary persists even in the face of the decline of the musical and cultural traditions that created and sustained them.

Abstract:

This article introduces the concept of orchestration as the mobilization of an intermediary by an orchestrator on a voluntary basis in pursuit of a joint governance goal. Orchestrator-Intermediary theory then provides a model of indirect governance that supplements delegation models premised on principal-agent theory. Under both theories, governors enhance their governance capacity by drawing on the capabilities of third parties. Whereas delegation is premised on hard ‘contractual’ control over the agent, however, orchestration relies on the soft control of like-minded intermediaries through material and ideational support. The two models overlap, and governors mix them in practice, but distinguishing between them analytically can broaden and deepen analysis of indirect forms of governance. This article discusses the circumstances under which each model provides a better fit for real-world problems, as well as the key limitations of each model. Among other things, orchestration is relatively more likely in democratic than authoritarian systems, when governors have limited direct capacities of their own and when veto players are more numerous. Orchestration is not always more desirable than delegation, but it provides an important alternative in some circumstances. Multiple examples from both domestic and international settings are used to illustrate this claim. The article closes with key considerations regarding the effectiveness and legitimacy of orchestration.

Abstract:

Network Function Virtualization is a new technology allowing for a elastic cloud and bandwidth resource allocation. The technology requires an orchestrator whose role is the service and resource orchestration. It receives service requests, each one characterized by a Service Function Chain, which is a set of service functions to be executed according to a given order. It implements an algorithm for deciding where both to allocate the cloud and bandwidth resources and to route the SFCs. In a traditional orchestration algorithm, the orchestrator has a detailed knowledge of the cloud and network infrastructures and that can lead to high computational complexity of the SFC Routing and Cloud and Bandwidth resource Allocation (SRCBA) algorithm. In this paper, we propose and evaluate the effectiveness of a scalable orchestration architecture inherited by the one proposed within the European Telecommunications Standards Institute (ETSI) and based on the functional separation of an NFV orchestrator in Resource Orchestrator (RO) and Network Service Orchestrator (NSO). Each cloud domain is equipped with an RO whose task is to provide a simple and abstract representation of the cloud infrastructure. These representations are notified of the NSO that can apply a simplified and less complex SRCBA algorithm. In addition, we show how the segment routing technology can help to simplify the SFC routing by means of an effective addressing of the service functions. The scalable orchestration solution has been investigated and compared to the one of a traditional orchestrator in some network scenarios and varying the number of cloud domains. We have verified that the execution time of the SRCBA algorithm can be drastically reduced without degrading the performance in terms of cloud and bandwidth resource costs.

Abstract:

This paper shows a flexible orchestration solution for deploying Cooperative, Connected, and Automated Mobility (CCAM) services in 5G and beyond networks. This solution is based on the concepts of federation and hierarchy of orchestration functions. The federated approach is leveraged to cope with the differentiated complexity operation when multiple network operators are considered, whereas the hierarchical approach addresses the issue of jointly orchestrating multiple edge platforms in the network of a single operator. In this complex orchestration architecture, the main contribution of this paper consists of the design and implementation of an Abstraction and Adaptation Layer (AAL) for edge clouds, a new component enabling a truly cooperative and coordinated orchestration between different edge systems, characterized by appreciable experimental performance in terms of latency.

Abstract:

Orchestrating collaborative learning activities is a challenge, even with the support of technology. Tangibles as orchestration tools represent an ambient and embodied approach to sharing information about the learning content and flow of the activity, thus facilitating both collaboration and its orchestration. Therefore, we propose tangibles as a solution to orchestrate productive collaborative learning. Concretely, this paper makes three contributions toward this end: First, we analyze the design space for tangibles as an orchestration tool to support collaborative learning and identify twelve essential dimensions. Second, we present five tangible tools for collaborative learning activities in face-to-face and online classrooms. Third, we present principles and challenges to designing tangibles for orchestrating collaborative learning based on our findings from the evaluation of ten educational experts who evaluated these tools using a usability scale and open questions. The key findings were: (1) they had good usability; (2) their main advantages are ease of use and support for collaborative learning; (3) their main disadvantages are limited functions and the difficulty to scale them to more users. We conclude by providing reflections and recommendations for the future design of tangibles for orchestration.

Abstract:

Container virtualization technology facilitates the creation of microservices-based systems through continuous integration. Container-based apps can be deployed more easily when they use orchestration systems like Kubernetes, which has become the de facto standard. It can be difficult to create effective and precise orchestration systems, nevertheless. The scheduler, a crucial orchestrator task that allocates physical resources to containers, is the subject of this article. Scheduling strategies are developed using several Quality-of-Service metrics. The CI in CI/CD stands for continuous integration. Continuous integration drives the automation in the development and delivery of the code and developers frequently apply code changes. It’s an automated process that allows multiple developers to contribute software components to the same project without integration conflicts. CI also triggers the process of testing the applications automatically upon code commit into the repository.

Abstract:

This paper discusses the trajectory of the instrumental meta-orchestration model (IMO) development, studies and results, and extensions. Instrumental meta-orchestration, developed as a solution for teacher training on instrumental orchestration (IO), relied on its development of concepts such as meta-situation, didactic meta-configuration, and meta-exploration model. An experimental study with its analysis led to the development of data visualisation instruments in an internal analysis context at the IO. These concepts and analysis instruments were used in research that followed that of the IMO, such as the extension of the IMO to interdisciplinary teachers’ education. The concepts of ad hoc reaction, artefacts such as didactic webdoc, and analysis of events between orchestrations show their potential and subsidise new research for teacher training in integrating digital technologies.

Abstract:

With the advent of 5G verticals and the Internet of Things paradigm, Edge Computing has emerged as the most dominant service delivery architecture, placing augmented computing resources in the proximity of end users. The resource orchestration of edge clouds relies on the concept of network slicing, which provides logically isolated computing and network resources. However, though there is significant progress on the automation of the resource orchestration within a single cloud or edge cloud datacenter, the orchestration of multi-domain infrastructure or multi-administrative domain is still an open challenge. Towards exploiting the network service marketplace at its full capacity, while being aligned with ETSI Network Function Virtualization architecture, this article proposes a novel Blockchain-based service orchestrator that leverages the automation capabilities of smart contracts to establish cross-service communication between network slices of different tenants. In particular, we introduce a multi-tier architecture of a Blockchain-based network marketplace, and design the lifecycle of the cross-service orchestration. For the evaluation of the proposed approach, we set up cross-service communication in an edge cloud and we demonstrate that the orchestration overhead is less than other cross-service solutions.

Design/methodology/approach The authors conducted literature reviews on the orchestration of innovation networks; and networking capabilities. Findings This study presents a theoretical model and a research agenda. Originality/value In interorganizational relations, a central actor can stand out the role of intentionally creating, extracting and distributing value in the network, generating gains for all members. Literature recognizes this set of intentional and deliberate actions as the “orchestration” of resources in the network. Despite the increasing interest regarding the theme, the phases and specific capabilities for orchestration still lack further investigation.

Abstract:

In this article, we present a proposal for instrumental orchestration that organizes the use of technological environments in online mathematics education, in the synchronous mode for the concepts of eigenvalue and eigenvector of a first linear algebra course with engineering students. We used the instrumental orchestration approach as a theoretical framework to plan and organize the artefacts involved in the environment (didactic configuration) and the ways in which they are implemented (exploitation modes). The activities were designed using interactive virtual didactic scenarios, in a dynamic geometry environment, guided exploration worksheets with video and audio recordings of the work of the students, individually or in pairs. The results obtained are presented and the orchestrations of a pedagogical sequence to introduce the concepts of eigenvalue and eigenvector are briefly discussed. This work allowed us to identify new instrumental orchestrations for online mathematics education.

Abstract:

IoT systems can be leveraged by Network Function Virtualization (NFV) and Software-Defined Networking (SDN) technologies, thereby strengthening their overall flexibility, security and resilience. In this sense, adaptive and policy-based security frameworks for SDN/NFV-aware IoT systems can provide a remarkable added value for self-protection and self-healing, by orchestrating and enforcing dynamically security policies and associated Virtual Network Functions (VNF) or Virtual network Security Functions (VSF) according to the actual context. However, this security orchestration is subject to multiple possible inconsistencies between the policies to enforce, the already enforced management policies and the evolving status of the managed IoT system. In this regard, this paper presents a semantic-aware, zero-touch and policy-driven security orchestration framework for autonomic and conflict-less security orchestration in SDN/NFV-aware IoT scenarios while ensuring optimal allocation and Service Function Chaining (SFC) of VSF. The framework relies on Semantic technologies and considers the security policies and the evolving IoT system model to dynamically and formally detect any semantic conflict during the orchestration. In addition, our optimized SFC algorithm maximizes the QoS, security aspects and resources usage during VSF allocation. The orchestration security framework has been implemented and validated showing its feasibility and performance to detect the conflicts and optimally enforce the VSFs.

Abstract:

This paper proposes a decentralized framework for the orchestration of Cloud Services using heterogeneous resources residing in the homes of private individuals or small-scale clusters. The framework makes use of Ethereum Smart Contracts to provide a decentralized mechanism for discovering the different interfaces exposed by Cloud Components. The paper introduces a novel concept of Component Administration Networks, which are peer-to-peer networks that monitor and ensure the availability of the software components. The concept applied for the Orchestration process to ensure that the deployment of an Application continues in the presence of Orchestrator component failure. Checkpoints are used to address the continuity of the Management components, in general, and of the Orchestrator, in particular. In our proposal, checkpoint metadata is stored in a Smart Contract to assess the execution time of a Service to reimburse the participants that ensure its execution.

Abstract:

Orchestrating technology-enhanced learning is a difficult task, especially in demanding pedagogical approaches like inquiry-based learning (IBL). To foster effective teacher adoption, both the complexity of designing IBL activities and the uncertainty about the student learning path during enactment need to be addressed. Previous research suggests that aligning learning design and learning analytics can be an effective way to provide such orchestration support. This paper reports on a design-based research (DBR) project to explore teachers’ orchestration needs in Go-Lab (a technological ecosystem for IBL used by thousands of primary and secondary school teachers around the world), and on how solutions that align learning design and analytics can fulfill such needs. The analysis of data from multiple events (including surveys, case studies, workshops with teachers, and platform usage analyses) led to a catalogue of IBL orchestration needs that can be tackled by aligning learning design and analytics, as well as a list of guidelines for technology development aiming to support IBL orchestration. These two contributions can support the creation of future learning analytics–enhanced IBL environments that are both pedagogically grounded and usable by teachers in authentic settings.

Abstract:

AbstractThis article examines the relationship between orchestration and microtonality in the music of Marc Sabat through a score-based analysis of two recent works, Asking Ocean (2016), for string quartet and large ensemble, and The Luminiferous Aether (2018), for large orchestra. Excerpts from these two compositions are discussed to highlight the challenges of composing for orchestral forces in a musical style that demands a high degree of microtonal pitch precision. Through retuning, alteration, and a sensitivity to the construction, techniques and performance practices of orchestral instruments, Sabat has developed a unique manner of orchestrating that is at once timbrally rich and uncompromising in pitch precision. After a brief introduction to the extended just intonation framework that Sabat employs, his concepts of ‘fixed microtonal pitches’ and ‘tuneable intervals’ are discussed and connected to orchestration in his scores. Drawing upon this analysis, connections are made between the microtonal system with orchestration and musical aesthetics broadly.

AbstractThe purpose of this study is to further our understanding of orchestrating math-talk with digital technology. The technology used is common in Swedish mathematics classrooms and involves personal computers, a projector directed towards a whiteboard at the front of the class and software programs for facilitating communication and collective exploration. We use the construct of instrumental orchestration to conceptualize a teacher’s intentional and systematic organization and use of digital technology to guide math-talk in terms of a collective instrumental genesis. We consider math-talk as a matter of inferential reasoning, taking place in the Game of Giving and Asking for Reasons (GoGAR).The combination of instrumental orchestration and inferential reasoning laid the foundation of a design experiment that addressed the research question: How can collective inferential reasoning be orchestrated in a technology-enhanced learning environment? The design experiment was conducted in lower-secondary school (students 14–16 years old) and consisted of three lessons on pattern generalization. Each lesson was tested and refined twice by the research team. The design experiment resulted in the emergence of the FlexTech orchestration, which provided teachers and students with opportunities to utilize the flexibility to construct, switch and mark in the orchestration of an instrumental math-GoGAR.

Abstract:

The Microservices architectural design is widely used today which helps one to build an application as a set of services that can be developed and deployed independently. Each service is independent and gives a set of functions or features that can be individually serviced. In spite of the fact that microservices design has been advanced as the fix just for all cutting-edge application development ailments and is viewed as the replacement for API first application advancement, its execution needs undeniably more idea and practicality. In order for these independent services to work together towards a common goal, we need something that will stitch them together because they cannot work in complete isolation and need to share data and interact with one another. There are two ways to do this – microservice choreography and microservice orchestration. This paper tries to explain the difference between choreography and orchestration of microservices, and why the latter is better. We will then discuss the orchestration of microservices using an open-sourced microservices orchestrator – Conductor.

Abstract:

Amid the current industrial revolution, a total disruption of the existing production lines may seem to be the easiest approach, as the potential possibilities seem limitless when starting from the ground up. On the business side, an adaptation of existing production lines is always a preferred option. In support of adaptation as opposed to disruption, this paper presents a new approach of using production process orchestration in a smart factory, discussed in an industrial case-study example. A proposed smart factory has the Orchestrator component in its core, responsible for complete semantical orchestration of production processes on one hand, and various factory resources on the other hand, in order to produce the desired product. The Orchestrator is a complex, modular, highly scalable, and pluggable software product responsible for automatised planning, scheduling, and execution of the complete production process. According to their offered capabilities, non-smart and smart resources—machines, robots, humans—are simultaneously and dynamically assigned to execute their dedicated production steps.

For the analysis two pieces of Maurice Ravel and Borys Lyatoshinsky – two prominent masters of orchestration and piano miniature of 20th century, were chosen. Their approaches are distinguishably different: (a) the detailed reordering of the initial idea from an “instrument Piano” to an “instrument Orchestra” (Ravel); (b) throughout development with essential changes firstly within piano means, than by orchestral means in the genre of Symphony (Lyatoshinsky).

Abstract:

The nature of vocational education needs has changed. In authentic vocational classroom contexts, there is a rising need to develop new ways to integrate ongoing and overlapping processes of students' personal learning environments and collaborative knowledge construction. However, there is currently very little knowledge about how teachers integrate these two approaches in arranging learning. This creates new challenges for teachers when creating instructional activities, especially regarding teacher-student interactions. This case study illuminates teachers' instructional activities in empowering the students' knowledge construction in a technology-enhanced learning setting. The results showed six main teacher-student interactions related to orchestrating learning. In addition, this study illustrates how vocational education teachers enhance students' learning in ways that meet working life needs (e.g., by selectively restructuring knowledge from the viewpoint of work settings).

Abstract:

Currently, energy efficiency (EE) of wireless communication is essential where many wireless networks with different Radio Access Technologies (RATs) coexist together. The RATs can be effectively selected and managed on a higher level to achieve maximum EE and save energy, e.g., save batteries. The approach to wireless traffic steering in mobile networks with a proof-of-concept solution is presented in this paper, owing to the developed high-level multi-RAT (multi-Radio Access Technology) heterogonous network orchestration approach. Based on the high-level network orchestrator, which traces network indicators, it is possible to decrease the user mobile terminal energy consumption, keeping traffic speed at an adequate level. The solution discussed was implemented in an experimental testbed with Software Defined Radio transmission systems. Downlink and uplink data links were toggled among different RATs according to the decisions that were taken by the end-to-end multi-RAT orchestrator based on the received proper network traffic-related indicators. The authors focused on finding an adequate algorithm that allowed for reduced power usage in the user terminal and made the attempt to verify how to reach the power reduction without introducing RAT-specific rules. The results showed that the proposed orchestration EE reduction was observed (from 11% to 42% for two different scenarios) in relation to the single LTE network deployment. The orchestration compared to the Wi-Fi network does not provide EE gain (−7% and 0%, respectively), but allows the user to achieve a higher data rate (23% and 39% gain, respectively), thus keeping the energy efficiency at almost the same level.

Abstract:

Purpose – The purpose of this study is to increase understanding of service innovation in networks. Especially the most loosely coupled forms of innovation networks, innovation communities, can be valuable in service innovation, but may not be manageable in the traditional sense. Rather, they may require orchestration characterized by discreet guidance that also accommodates the specific nature of services. Through informed orchestration, it is possible to deal with several contingencies, and influence the absorptive capacity at the network level to generate new service innovations. Design/methodology/approach – These issues are examined through literature review and a case study. Findings – The findings suggest that individual orchestration mechanisms may be more closely connected to certain contingencies than others, and that both orchestration mechanisms and contingency factors have a role in absorptive capacity development within service innovation networks. Research limitations/implications – While the case study approach limits the possibility to make wide generalizations, the in-depth insights provide valuable knowledge. Practical implications – There has been a shift from inter-firm competition towards competition between networks of organizations, increasing relevance of absorptive capacity at the network level. Originality/value – Despite the recent increase in service innovation literature, research on service innovation taking place in networks is scant. Knowledge on some aspects can be derived from more traditional notions on technological innovation, but both the distinctive features of services and central characteristics of innovation networks make it necessary to reconsider some of the established views. In particular, managing – or rather orchestrating – service innovation is still a challenging area.

Abstract:

Coherence is a crucial issue in orchestrating Sustainable Development Goals (SDGs) at the society level. The various parties involved with different language standards further increase the complexity of communication. Enterprise Architecture (EA), which emphasizes consistency and coherence as the pillars of its concept, can be used to address coherence issues in the SDGs orchestration. This study aims to build a Requirements Framework for developing an architecture description language as a domain-specific language used for EA-based SDGs orchestration. To clarify the purpose of the research, a motivating scenario was built in the form of the SDGs Participation Platform (SDGs-PP). SDGs-PP becomes the context in which EA-based SDGs orchestration involves society-level actors (orchestrators) and enterprise-level actors (enterprise architects). This Requirement Framework is built using design science methodology as a part of ongoing research. The requirements consisting of context, concept, and collaboration domains and nine action requirements (elicit, separate, connect, classify, manifest, map, arrange, separate, and set up) were successfully formulated. The Context domain was developed from the ISO/IEC/IEEE 42010 standard. The Concept domain focuses on elaborating the SDGs means of implementation and the business ecosystem concept. The Collaboration domain discusses the separation in the model canvas between the enterprise and society domains. Apart from being used as a requirement framework for the meta-model development of an architecture description language, the results of this study can also be used further as a research framework in the domain of EA-based SDGs orchestration.

Abstract:

Intent Based Networking (IBN) is a promising approach for automating and managing large and complex networks. Integrating Voice-enabled Virtual Assistants (VVAs) with IBN and Software Defined Networking (SDN) has improved network management efficiency and flexibility. However, there is still room for optimization improvement in installing intents in industrial scenarios. Network Orchestration Automation plays an important role within the Beyond 5G and 6G Networks, considering existing practices for orchestrating 5G Network Functions. This work presents an extended preliminary architecture for a voice-enabled IBN system called VINIA for industrial network automation. The new approach allows the configuration of more network assets (e.g., 5G networks), leveraging Network Orchestrators and Network Slice Managers, thus improving the system?s capabilities. The results provide insights into this solution?s potential benefits and limitations to enhance the automation of industrial networks? management and orchestration procedures.

Abstract:

The automotive industry requires ultra-reliable low-latency connectivity for its vehicles, and as such, it is one of the promising customers of 5G ecosystems and their orchestrated network infrastructure. In particular, Multi-Access Edge Computing (MEC) provides moving vehicles with localized low-latency access to service instances. However, given the mobility of vehicles, and various resource demand patterns at the distributed MEC nodes, challenges such as fast reconfiguration of the distributed deployment according to mobility pattern and associated service and resource demand need to be mitigated. In this paper, we present the orchestrated edges platform, which is a solution for orchestrating distributed edges in complex cross-border network environments, tailored to Connected, Cooperative, and Automated Mobility (CCAM) use cases within a 5G ecosystem. The proposed solution enables collaboration between orchestrators that belong to different tiers, and various federated edge domains, with the goal to enable service continuity for vehicles traversing cross-border corridors. The paper presents the prototype that we built for the H2020 5G-CARMEN trials, including the validation of the orchestration design choices, followed by the promising results that span both orchestration (orchestration latency) and application performance-related metrics (client-to-edge and edge-to-edge service data plane latencies).

Abstract:

This paper demonstrates the use of software-defined networking (SDN) orchestration to integrate regionally separated networks in which different network parts use incompatible key management systems (KMSs) managed by different SDN controllers to ensure end-to-end QKD service provisioning to deliver the QKD keys between geographically different QKD networks. The study focuses on scenarios in which different parts of the network are managed separately by different SDN controllers, requiring an SDN orchestrator to coordinate and manage these controllers. In practical network deployments, operators often utilize multiple vendors for their network equipment. This practice also enables the expansion of the QKD network’s coverage by interconnecting various QKD networks equipped with devices from different vendors. However, as coordinating different parts of the QKD network is a complex task, this paper proposes the implementation of an SDN orchestrator which acts as a central entity to manage multiple SDN controllers, ensuring end-to-end QKD service provisioning to address this challenge. For instance, when there are multiple border nodes to interconnect different networks, the SDN orchestrator calculates the path in advance for the end-to-end delivery of keys between initiating and target applications belonging to different networks. This path selection requires the SDN orchestrator to gather information from each SDN controller managing the respective parts of the QKD network. This work shows the practical implementation of SDN orchestration for interoperable KMS in commercial QKD networks in South Korea. By employing an SDN orchestrator, it becomes possible to coordinate multiple SDN controllers and ensure the efficient and secure delivery of QKD keys between different QKD networks with varying vendor equipment.

Abstract:

The exponential growth of data complexity in an era marked by the rapid expansion of the computer environment has led to an increase in the demand for scalable and effective systems. The crucial stage of data management, which acts as a vital conduit for accelerating the processing of enormous amounts of data, is at the centre of this paradigm. Scientific workflows must be coordinated in order to orchestrate the management of large datasets within this complex ecosystem. These workflows differ from generic workflows in that they involve a complex interplay of scheduling, algorithms, data flow, processes, operational protocols, and a focused attention on data-intensive systems. Software as a Service's (SaaS) distinctive feature of multi-tenancy is inextricably related to the growth of the industry. In this complex fabric, the investigation of scientific processes reveals a mutually beneficial relationship with the multi-tenant cloud orchestration environment, revealing a realm that goes beyond simple control and data propagation. It opens a fresh path for system development and makes service delivery's previously hidden facets visible. This study pioneers an exploration into a thorough framework for scientific operations within the context of multi-tenant cloud orchestration. Semantics-based workflows, which leverage semantics to help users manage the complexities of data orchestration, form the basis of this paradigm. In addition, policy-based processes provide another level of intricacy, giving users a flexible way to manoeuvre the complex environment of multi-tenancy, orchestration, and service identification. The study focuses on the fundamentals of orchestrating scientific workflows in a multi-tenant cloud environment, where the creative, scalable, and effective composition results from the harmonious integration of data and semantics under the guidance of rules.

Abstract:

With the rapidly growing popularity of cloud services, the cloud computing faces critical challenges to orchestrate the deployment and operation of cloud applications on heterogenous cloud platforms. Cloud applications are built on a platform model that abstracts away underlying platform-specific details, so that their orchestration can benefit from the abstract view and flexibility of the underlying platform configuration. However, considerable efforts are still required to properly manage complicated cloud applications. This paper proposes a model-driven approach to cloud application orchestration which promotes the concerns of distinct roles for cloud system provisioning and operation. By establishing a set of capabilities as modeling constructs, our approach allows TOSCA-based application topology itself and its orchestration needs to be specified in a way to provide a more targeted support for different needs and concerns of application developers and operators. With novel orchestration features like application topology description, platform capability modeling, and role-awareness for cloud application orchestration, it can significantly reduce the complexity of application orchestration in diverse cloud environments. To show the feasibility and effectiveness of our proposal for cloud application orchestration, we present a proof-of-concept orchestration system implementation and evaluate its deployment and orchestration results in a Kubernetes cluster.

Abstract:

Purpose The purpose of this paper is to examine the mechanisms through which the use of enterprise systems (ESs) enhances buyer-supplier integration (BSI). More specifically, the authors explain a model where ES enhances BSI indirectly, mediated by inventory management capabilities (IMCs), as the way ES enhances BSI remains under-explored in the literature. Design/methodology/approach Application of the resource orchestration framework to explain how capabilities and mechanisms interplay to enhance BSI. Data were collected by means of a survey instrument. Data collection took place as part of a larger project, sponsored by the Spanish Government, to evaluate logistics competitiveness in Spain. Findings ES enhances BSI by serving as a coordinating mechanism that maintains capability configurations in a value-creating alignment. IMC plays a key, yet under-explored role as a mediating mechanism that supports ES-enabled BSI. Research limitations/implications First, this research does not fully capture the multi-party nature of the supply chain context. Second, data collection was limited to companies that were more likely to have a systematic approach to logistics issues (i.e. large- and medium-sized companies) and companies based in Spain. Originality/value This paper enhances both scholarly and practitioner understanding of the mechanisms through which the implementation and use of ES contributes to BSI. In addition, this paper integrates literature from different fields (e.g. strategy, information systems, and operations) to gain a better understanding of how the implementation and use of ES affects BSI.
