    Bid-Centric Cloud Service Provisioning

    Full text link
    Bid-centric service descriptions have the potential to offer a new cloud service provisioning model that promotes portability, diversity of choice and differentiation between providers. A bid matching model based on requirements and capabilities is presented that provides the basis for such an approach. In order to facilitate the bidding process, tenders should be specified as abstractly as possible so that the solution space is not needlessly restricted. To this end, we describe how partial TOSCA service descriptions allow for a range of diverse solutions to be proposed by multiple providers in response to tenders. Rather than adopting a lowest common denominator approach, true portability should allow for the relative strengths and differentiating features of cloud service providers to be applied to bids. With this in mind, we describe how TOSCA service descriptions could be augmented with additional information in order to facilitate heterogeneity in proposed solutions, such as the use of coprocessors and provider-specific services

    The internationalization processes of cloud service providers in Finland

    This study focuses on the internationalization processes of the Finnish cloud service providers, in both pre- and post-phases. As this new kind of service model is likely to have a disrupting impact on the existing theoretical models, this study aims to observe to what extent it reshapes these models and what kind of new possibilities it offers for companies when it comes to their internationalization. The study consists of a theoretical and empirical part. The first theoretical part examines the current state of the international services and what kind of new features cloud computing adds to this setting. In the second part processes and theories relating to the internationalization are presented from various perspectives to offer an extensive foundation on the existing research, on which the theoretical framework is built on. This framework is then compared against the empirical part to find out which of these traditional theories also apply today in the era of cloud computing and which do not. Qualitative research methods were chosen for this study, and ten Finnish cloud service providers were interviewed to collect data for further analysis. Based on the interviews and the data analysis the increasing role of cloud computing was identified. Many of its elements are not yet fully utilized, mainly stemming from its young nature, but it is likely to cause more rapid internationalization processes in the future for various kind of companies. Currently the challenges for service providers to expand more quickly internationally rise from the customers’ side, as many are still concerned about the legal and security issues and do not fully understand the concept. However, attitudes are likely to change in the near future as both the offerings and the legal aspects become clearer. The triggers for Finnish cloud service providers to internationalize are also increasing, as the competition within the home market is becoming fiercer. Also, Finland offers a favorable environment for cloud computing from the customers’ point of view, which is likely to impact positively on service providers’ desire to target global customers.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format

    A Proposal of Business Model Design Parameters for Future Internet Carriers

    Get PDF
    Future Internet evolution requires innovative strategic stances and the design of original business models from actors involved in the ecosystem. The study focuses on Internet Carriers, recently striving to make their business sustainable, and proposes to enclose in a single reference framework all the critical levers, either consolidated or innovative, such actors can employ in order to design their value proposition, value network integration, and financial configuration. The framework grounds its findings on multiple case studies, and, by presenting an insightful list of business model parameters for Carriers, sheds light on key emerging strategic and tactical trends in the Internet interconnections market

    Business-driven resource allocation and management for data centres in cloud computing markets

    Get PDF
    Cloud Computing markets arise as an efficient way to allocate resources for the execution of tasks and services within a set of geographically dispersed providers from different organisations. Client applications and service providers meet in a market and negotiate for the sales of services by means of the signature of a Service Level Agreement that contains the Quality of Service terms that the Cloud provider has to guarantee by managing properly its resources. Current implementations of Cloud markets suffer from a lack of information flow between the negotiating agents, which sell the resources, and the resource managers that allocate the resources to fulfil the agreed Quality of Service. This thesis establishes an intermediate layer between the market agents and the resource managers. In consequence, agents can perform accurate negotiations by considering the status of the resources in their negotiation models, and providers can manage their resources considering both the performance and the business objectives. This thesis defines a set of policies for the negotiation and enforcement of Service Level Agreements. Such policies deal with different Business-Level Objectives: maximisation of the revenue, classification of clients, trust and reputation maximisation, and risk minimisation. This thesis demonstrates the effectiveness of such policies by means of fine-grained simulations. A pricing model may be influenced by many parameters. The weight of such parameters within the final model is not always known, or it can change as the market environment evolves. This thesis models and evaluates how the providers can self-adapt to changing environments by means of genetic algorithms. Providers that rapidly adapt to changes in the environment achieve higher revenues than providers that do not. Policies are usually conceived for the short term: they model the behaviour of the system by considering the current status and the expected immediate after their application. This thesis defines and evaluates a trust and reputation system that enforces providers to consider the impact of their decisions in the long term. The trust and reputation system expels providers and clients with dishonest behaviour, and providers that consider the impact of their reputation in their actions improve on the achievement of their Business-Level Objectives. Finally, this thesis studies the risk as the effects of the uncertainty over the expected outcomes of cloud providers. The particularities of cloud appliances as a set of interconnected resources are studied, as well as how the risk is propagated through the linked nodes. Incorporating risk models helps providers differentiate Service Level Agreements according to their risk, take preventive actions in the focus of the risk, and pricing accordingly. Applying risk management raises the fulfilment rate of the Service-Level Agreements and increases the profit of the providerPostprint (published version

    Internet Interconnection Techno-economics: A Proposal for Assured Quality Services and Business Models

    Get PDF
    The Internet is constructed by means of complex business interconnection agreements among multiple networks. However, the most commonly used agreements do not contain explicit Quality of Service reference. In this study a business rationale for Assured Service Quality (ASQ) inter-network services is presented and potential business models for their realization are proposed and analyzed. It is argued that ASQ products and business models could greatly enhance the health of the Internet interconnection ecosystem. A business model design framework that encompasses the key strategic decisions that would enable ASQ provisioning and generic collaboration is also provided. This framework is then elaborated using a number of off-net content delivery scenarios. Conclusions are hence drawn on the role of ASQ and ASQ-driven business models for the sustainable development of the "Future Internet"

    Implementation plan of health and safety processes

    Get PDF
    An auditor was asked to review an organisation’s Health and Safety procedures to assess compliance with the new legislation imposed by The Health and Safety Act 2015. Then the organisation approached an internal source to conduct a strategic plan in order to target issues of health and safety risk. An implementation plan will be designed to achieve the auditors recommendations and improve the organisation’s Health and Safety practices. Research and audit of the current policies and procedures used at the organisation must be conducted in order to gain a better understanding of the current issues and from there develop action plans and a strategy on how to reach those action plans. Current documentation of policies and an interview with management will be analysed to detail the potential action plans.Once the research has been conducted, results will be used to determine conclusions
