“…From what we observed in the literature, cloud interoperability solutions are not restricted to achieve the interoperability between services only, but also to address other aspects such as cloud portability, composition, design, deployment, discovery, migration, configuration, provisioning, adaptability monitoring, management, description, and integration …”

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.

“…To address scalability and security, a hierarchical network service is suggested and, in the higher levels, inter-site forwarding enables connectivity between a site VAN fragment and a fragment of the VAN located at a remote site using VAN proxies. This approach has been continued [9] and adopted by the EU project BEACON [3]. Also, the EU project NOVI [10] created a federated testbed, combining PlanetLab and FEDER-ICA, based on the NSwitch, a distributed virtual switch based on Open vSwitch that enables a virtual entity in one domain to be connected at protocol layer 2 with another virtual entity in a remote domain.…”

“…Many different federation scenarios for clouds and datacenters have been proposed and implemented [1][2][3], such as cloud brokering, cloud peering, or hybrid cloud architectures, among others, which exhibit different level of coupling and interoperation among the cloud resources. One of the most explored federation scenarios is the hybrid cloud model [4][5][6], also called cloud bursting, which combines the existing on-premise cloud infrastructure (e.g., a private cloud managed by a cloud manager, such as OpenNebula and OpenStack) with external resources from one or more remote clouds, which can be either public clouds (e.g.…”

Federated cloud networking is needed to allow the seamless and efficient interconnection of resources distributed among different clouds. This work introduces a new cloud network federation framework for the automatic provision of Layer 2 (L2) and layer 3 (L3) virtual networks to interconnect geographically distributed cloud infrastructures in a hybrid cloud scenario. After a revision of existing encapsulation technologies to implement L2 and L3 overlay networks, the paper analyzes the main topologies that can be used to construct federated network overlays within hybrid clouds. In order to demonstrate the proposed solution and compare the different topologies, the article shows a proof-of-concept of a real federated network deployment in a hybrid cloud, which spans a local private cloud, managed with OpenNebula, and two public clouds, two different regions of Amazon EC2. Results show that L2 and L3 overlay connectivity can be achieved with a minimal bandwidth overhead, lower than 10%.

“…In recent years, Cloud computing and IoT paradigms along with the concept of the federation have been combined so that different variants born. The first paradigm variation regarded Cloud federation that was defined as a mesh of Cloud providers that are interconnected to provide a universal decentralized computing environment where everything is driven by constraints and agreements in a ubiquitous, multi-provider infrastructure [3]. With the advent of IoT, the IoT Cloud paradigm raised.…”

In a pandemic situation such as that we are living at the time of writing of this paper due to the Covid-19 virus, the need of tele-healthcare service becomes dramatically fundamental to reduce the movement of patients, thence reducing the risk of infection. Leveraging the recent Cloud computing and Internet of Things (IoT) technologies, this paper aims at proposing a tele-medical laboratory service where clinical exams are performed on patients directly in a hospital by technicians through IoT medical devices and results are automatically sent via the hospital Cloud to doctors of federated hospitals for validation and/or consultation. In particular, we discuss a distributed scenario where nurses, technicians and medical doctors belonging to different hospitals cooperate through their federated hospital Clouds to form a virtual health team able to carry out a healthcare workflow in secure fashion leveraging the intrinsic security features of the Blockchain technology. In particular, both public and hybrid Blockchain scenarios are discussed and assessed using the Ethereum platform.
