C2TP: A Service Model for Cloud:    InderScience    [Oct 2011]

  An ICT organization will reach a “cross road” or an “equilibrium” where the organization is required to make a conscious decision to either enhance the existing on premise investment or procure IT capability via cloud computing providers. This paper articulates the C2TP model that is purposely built to address this concern. ..........

 

Validating and designing a service centric view for C2TP:    KES    [Jul 2010]

  This presentation attempts to extend current research efforts in cloud computing by creating a value model for ICT organisations to objectively determine to invest in either cloud computing or continue investing with on premise hosting options. The model will attempt to factor ICT organisation’s business attributes, financial attributes and technical attributes to provide a balanced view. Previously the authors of this paper have proposed a Cloud Computing Tipping Point model to address these gaps in research. The author also attempts to enable the model with package of services to exchange information with 3rd parties and agents that consumes the model. This paper attempts to validate the Cloud Computing Tipping Point model by leveraging surveys. The paper also attempts to validate the model by creating an artifact to demonstrate the model’s capability. It continues to discusses the authors attempt to enable service centric capability by leveraging service oriented architecture (SOA) concepts. This paper concludes by introducing a standard based XML taxonomy to exchange information between the model and its clients or agents. ..........

 

Service Centric Model for Cloud Computing Tipping Point:    SMU    [May 2010]

  Recently a continuing trend toward IT industrialization has grown in popularity. IT services delivered via hardware, software and people are becoming repeatable and usable by a wide range of customers and service providers. This is due, in part, to the commoditization and standardization of technologies, virtualization and the rise of service-oriented software architectures, and (most importantly) the dramatic growth in popularity/use of the Internet and the Web. Taken together, they constitute the basis of a discontinuity that amounts to a new opportunity to shape the relationship between those who use IT services and those who sell them. The discontinuity implies that the ability to deliver specialised services in IT can be paired with the ability to deliver those services in an industrialised and pervasive way. The reality of this implication is that users of IT-related services can focus on what the services provide them, rather than how the services are implemented or hosted. Analogous to how utility companies sell power to subscribers, and telephone companies sell voice and data services, some IT services such as network security management, data centre hosting or even departmental billing can now be easily delivered as a contractual service. This notion of cloud computing capability is gathering momentum rapidly. However, the governance and enterprise architecture to obtain repeatable, scalable and secure business outcomes from cloud computing is still greatly undefined. This paper attempts to evaluate the enterprise architecture features of cloud computing and investigates a model that an IT organisation can leverage to predict / evaluate the ‘tipping point’ where an organisation can make an objective decision to invest in cloud computing. Current research results are attempting to build a quantitative and qualitative service centric framework by mapping cloud computing features with ValIT and COBIT industry best practices. ..........

 

Cloud Computing Value Proposition: An Interrogation:    SMU    [May 2010]

  In the current era of competitive business world and stringent market share and revenue sustenance challenges, organizations tend to focus more on their core competencies rather than the functional areas that support the business. However, traditionally this has not been possible in the IT management area because the technologies and their underlying infrastructures are significantly complex thus requiring dedicated and sustained in house efforts to maintain IT systems that enable core business activities. Senior executives of organisations are forced in many cases to conclude that it is too cumbersome, expensive and time consuming for them to manage internal IT infrastructures. This takes the focus away from their core revenue making activities. This scenario facilitates the need for external infrastructure hosting, external service provision and outsourcing capability. This trend resulted in evolution of IT outsourcing models. The authors attempted to analyse the option of leveraging the cloud computing model to facilitate this common scenario. This paper initially discusses the characteristics of cloud computing focusing on scalability and delivery as a service. The model is evaluated using two case scenarios, one is an enterprise client with 30,000 worldwide customers followed by a small scale subject matter expertise through small to medium enterprise (SME) organisations. The paper evaluates the findings and develops a value model to articulate the value proposition of cloud computing.. The value model takes into consideration the financial aspects, and the behaviors and IT control structures of an IT organisation. ..........

 

Azure: Leveraging the Windows Platform in the Cloud:    AIIA    [Feb 2009]

  This presentation investigates and explores the Software Plus Services (S+S) strategy of Microsoft. It explores the Azure platform and articulates the hosted application model that can brings significant benefits (i.e. infinite scale, time to market, tight control of infrastructure costs) to enterprises. ..........
