“…The intercloud intermodel interoperability was the subject of 22 approaches (approximately 25%, 16 client‐centric, and six provider‐centric): PaaS/IaaS interoperability . To achieve this interoperability, the authors proposed approaches to leverage the span of IaaS solutions and approaches based on model‐driven techniques as well as vendor‐agnostic APIs .…”

“…Therefore, the developers will focus on the development logic rather than the implementation details. Several solutions were used to achieve data interoperability: In the client‐centric category, semantic technologies and brokers were key enablers of data interoperability. In the provider‐centric category, the authors proposed: common data interchange formats, middleware, agent‐based solution, and protocols …”

“…The cloud for Europe (C4E) and the Broker@Cloud are European initiatives that were introduced within the seventh framework program. The aim of C4E was to promote the creation of a digital single market for cloud computing services (CCSs) in Europe and to achieve cross‐border interoperability between public sector organizations. The authors were tenderers in the joint precommercial procurement instrument.…”

“…Many research and academic studies addressed the service interoperability and the vendor lock‐in problem in both single and interconnected clouds environments. The researchers proposed solutions such as standardization, brokering, model‐driven approaches, and semantic‐based solutions . There are five major cloud actors that were described in the cloud computing reference architecture: cloud consumer, cloud provider, cloud broker, cloud auditor, and cloud carrier.…”

A survey on the service interoperability in cloud computing: Client‐centric and provider‐centric perspectives

The vendor lock-in is a prominent issue in cloud computing. It is caused by cloud providers who offer proprietary services, which hinders the cloud interoperability. Client-centric interoperability enables the migration of the data and applications across clouds; it gives the clients control over their workloads and a wider range of service choices. Whereas, provider-centric interoperability allows the providers to collaborate. Thus, providers, who have spare resources, can lend them to other providers who lack computational or storage capabilities to overcome the limitations of their local resources. In this article, we conduct a survey to differentiate between client-and provider-centric interoperability solutions. We aim to provide an up-to-date analysis of the current tendencies and the neglected areas of the cloud interoperability field. Thus, we study the cloud service interoperability evolution through the years. Furthermore, we propose definitions for the intra-cloud and inter-cloud interoperability. Moreover, we propose a taxonomy to classify the cloud interoperability approaches into client-centric and provider-centric categories. Then, for each category, we classify the approaches based on their interoperability environment into single cloud or interconnected clouds. Finally, we analyze and compare the approaches based on multiple criteria. The study reveals the focus on the client-centric solutions and the interoperability in interconnected clouds. We notice more interest in the data and application levels interoperability, mainly, in infrastructure as a service model. We also find that client-centric solutions are, mostly, semantic technologies and brokers. However, provider-centric solutions are middleware, protocols, and standards. We conclude that a generic cloud service interoperability model is needed.

The ICT industry and specifically critical sectors, such as healthcare, transportation, energy and government, require as mandatory the compliance of ICT systems and services with legislation and regulation, as well as with standards. In the era of cloud computing, this compliance management issue is exacerbated by the distributed nature of the system and by the limited control that customers have on the services. Today, the cloud industry is aware of this problem (as evidenced by the compliance program of many cloud service providers), and the research community is addressing the many facets of the legal-rule compliance checking and quality assurance problem.\ud \ud Cloud service brokerage plays an important role in legislation compliance and QoS management of cloud services. In this paper we discuss our experience in designing a legal-rule and QoS-aware cloud service broker, and we explore relate research issues. Specifically we provide three main contributions to the literature: first, we describe the detailed design architecture of the legal-rule and QoS-aware broker. Second, we discuss our design choices which rely on the state of the art solutions available in literature. We cover four main research areas: cloud broker service deployment, seamless cloud service migration, cloud service monitoring, and legal rule compliance checking. Finally, from the literature review in these research areas, we identify and discuss research challenges

Nowadays cloud services are gaining their momentum. A Service Level Agreement (SLA) represents an agreement between a service provider and a customer for a particular service provision. Cloud providers and services are often selected more dynamically than in traditional IT services. Hence, services need to be compared according both to technical aspects and the promised SLAs, but no widely accepted model, standard or best practice, that would lead to a more rigorous SLA comparison, are currently available. In this paper, we present a conceptualization of SLAs including the explicit modeling of formulas for service level indicators, and its corresponding open, reusable ontological representation. On its top, we provide operators for analysis and comparison of SLAs, relying on a reasoning framework in Logic Programming capable to manipulate indicator formulas and other SLA features. We provide an evaluation by considering a cloud scenario where several SLAs have to be compared.
