A Literature Review on Cloud Computing Adoption Issues in Enterprises
2014
Part 3: Creating Value through Applications; International audience; Cloud computing has received increasing interest from enterprises since its inception. With its innovative information technology (IT) services delivery model, cloud computing could add technical and strategic business value to enterprises. However, cloud computing poses highly concerning internal (e.g., Top management and experience) and external issues (e.g., regulations and standards). This paper presents a systematic literature review to explore the current key issues related to cloud computing adoption. This is achieved by reviewing 51 articles published about cloud computing adoption. Using the grounded theory approa…
An Overview of Cloud Computing Adoption Challenges in the Norwegian Context
2014
Cloud computing is dominating European countries' Information and Communication Technology (ICT) agenda. Although the European cloud market is mostly mature, there are still challenges to overcome. Norway is one of the European countries facing such challenges, despite it is a developed country in terms of quality of life and ICT development. This paper identifies the current state of cloud computing adoption challenges in Europe in general and Norway in specific, and the way they are addressed. This is achieved through analyzing research articles, reports published by consulting companies and official bodies, official online news articles, and documents published by official authorities. T…

FederatedCloudSim
2014
Recent developments show that the standardization of cloud service descriptions and exchange leads the way for the rise of cloud federations. In these federations CSPs (cloud service providers) can use resources of other CSPs in the case of a lack of local resources or they can add remote services to their catalogue. Cloud federations again demand for cloud brokers which offer the resources and services of different CSPs transparently to the users. Research of cloud federations in the real world is very complex and expensive as distributed hard- and software scenarios are needed. Therefore we present FederatedCloudSim, a very flexible cloud simulation framework that can be used to simulate …
Self-establishing a Service Level Agreement within Autonomic Cloud Networking Environment
2014
International audience; Today, cloud networking which is the ability to connect the user with his cloud services and to interconnect these services within an inter-cloud approach, is one of the recent research areas in the cloud computing research communities. The main drawback of cloud networking consists in the lack of Quality of Service (QoS) guarantee and management in conformance with a corresponding Service Level Agreement (SLA). Several research works have been proposed for the SLA establishing in cloud computing, but not in cloud networking. In this paper, we propose an architecture for self-establishing an end-to-end service level agreement between a Cloud Service User (CSU) and a …
Autonomic Brokerage Service for an End-to-End Cloud Networking Service Level Agreement
2014
8 pages; International audience; Today, cloud networking which is the ability to connect the user with his cloud services and to interconnect these services within an inter-cloud approach, is one of the recent research areas in the cloud computing research communities. The main drawback of cloud networking consists in the lack of Quality of Service (QoS) assurance and management in conformance with a corresponding Service Level Agreement (SLA). In this paper, we propose a framework for self-establishing an end-to-end service level agreement between a Cloud Service User (CSU) and multiple Cloud Service Providers (CSPs) in a cloud networking environment using brokerage service. We focus on Qo…
Adding semantics to cloud computing to enhance service discovery and access
2012
Cloud computing is a technological paradigm that permits to offer computing services over the Internet. This new service model is closely related to previous, well-known distributed computing initiatives such as Web services and grid computing. In the current socio-economic climate, the affordability of cloud computing has gained it popularity among today's innovations. Under these circumstances, more and more cloud services become available. Consequently, it is becoming more and more difficult for service consumers to find and access those cloud services that fulfill their requirements. In this work, a cloud computing ontology is proposed that facilitates a semantic identification, discove…
Role of Data Communications in Hybrid Cloud Costs
2011
Rapid adoption of cloud services in recent years has been driven by multiple factors, such as faster time-to-market and improved scalability enabled by public cloud infrastructure. Hybrid clouds, combining the in-house capacities with on-demand capacity of public clouds, achieve both the increased utilization rate of the in-house infrastructure and the limited use of more expensive public cloud, thereby lowering the total costs for the cloud user. In this paper, an analytical model of hybrid cloud costs is introduced, wherein the costs of computing and data communication are taken into account. Using this model, the costefficient division of the computing capacity between the private and th…
Problemática laboral de los socios trabajadores de las empresas de Economía Social: ¿socios o trabajadores?
1999
Co-operatives and labour societies are the most important organisations within the framework of Social Economy. The establishment of these societies, which create employment in the private sector with a democratic philosophy based on mutual help, has been recently boosted thanks to the support of public power. Their growing importance can be explained by three factors: the Employment Policy, the Social Policy and the productive decentralisation. As far as labour is concerned, these societies offer the following advantages: intensive use of labour, high rate of stability in employment, high levels of productivity, training and surplus re-inversion, lower rate of inflation, fewer conflicts th…
