  • ESOCC Workshops - Cloud Migration Architecture and Pricing – Mapping a Licensing Business Model for Software Vendors to a SaaS Business Model
    Communications in Computer and Information Science, 2018
    Co-Authors: Frank Fowley, Claus Pahl
    Abstract:

    Cloud migration is about moving an on-premise software system into the Cloud. Many approaches exist that describe the technical migration analysis and the architectural migration. Equally, Cloud cost Models have been investigated. What we aim to investigate here is to link architecture and software utilisation to costing and business Models. We specifically look at software vendors that use the Cloud to provide their solutions to customers. They might face the challenges to migrate an in-house developed and provided product onto a Cloud IaaS or PaaS platform, while also mapping a licensing Model onto a Cloud monetisation Model. We provide here an experience report. This is based on experience with five migration case studies. We discuss the migration process under consideration of cost aspects, covering both income and expenses in the Cloud in relation to the Cloud Delivery Model chosen. We focus on one of the case studies to illustrate the concepts and observations.

  • Cloud blueprints for integrating and managing Cloud federations
    Lecture Notes in Computer Science, 2012
    Co-Authors: Mike P Papazoglou
    Abstract:

    Contemporary Cloud technologies face insurmountable obstacles. They follow a pull-based, producer-centric trajectory to development where Cloud consumers have to ‘squeeze and bolt' applications onto Cloud APIs. They also introduce a monolithic SaaS/PaaS/IaaS stack where a one-size-fits-all mentality and vendor lock-in prevail. As a consequence consumers cannot mix and match functionality from diverse tiers of the Cloud stack --- horizontally or vertically --- dynamically configuring it to address their needs. This paper presents an approach that overcomes these obstacles by providing an innovative reference architecture, an enhanced Cloud Delivery Model which breaks down the rigidity of the Cloud stack and transforms it into modular and easily combined components, and a complete integration and management environment that offers integration-as-a-service functionality.

  • CBI (1) - Integrating Security Risk Management into Business Process Management for the Cloud
    2014 IEEE 16th Conference on Business Informatics, 2014
    Co-Authors: Elio Goettelmann, Nicolas Mayer, Claude Godart
    Abstract:

    Security issues are still preventing wider adoption of Cloud computing, especially for businesses which are handling sensitive information. Indeed, by outsourcing its information system (IS), a company can lose control over its infrastructure, its software or even its data. Therefore, new methods and tools need to be defined to respond to this challenge. In this paper we propose to integrate Security Risk Management approaches into Business Process Management to effectively treat security issues at the early phases of the Information System construction. We focus on Cloud brokers, emerging actors of the Cloud Delivery Model, who enhance and aggregate existing Cloud services to match them with their Cloud consumers' requirements. Our main goal is to provide them with tools and techniques to increase the global security level of an IS through different risk treatment strategies.

  • an approach to identify and monitor sla parameters for storage as a service Cloud Delivery Model
    Global Communications Conference, 2012
    Co-Authors: Nirnay Ghosh, Soumya K Ghosh
    Abstract:

    Cloud computing is an emerging technological paradigm that follows pay-as-you-use Model. By this Model, the consumers are charged according to the usage without regard to where the services are hosted or how they are delivered. Usually Cloud services are offered as various Delivery Models among which Storage-as-a-Service Cloud is gaining interest in recent time. In this Model, raw (block) storage is offered as a service. Like any other utility services, Cloud negotiates its service levels and guarantees with its consumers by establishing Service Level Agreements (SLAs). SLA is important in any provider-consumer interaction as it defines a formal basis for performance and availability the provider guarantees to deliver. It consists of a set of measurable attributes called SLA parameters which are established by some objectively measurable conditions, termed as Service Level Objectives (SLOs). However, the SLAs provided by the present day state-of-the-art Clouds are relatively biased towards vendors and do not provide any formal method of verifying if the guarantees are complying or not. This paper attempts to identify the SLA parameters for Storage-as-a-Service Cloud Delivery Model and proposes a monitoring framework for compliance checking.
