A decision framework for cloud migration: A hybrid approach

Abstract

Cloud computing is utilised for information technology outsourcing of either industries or organisations. There are several inhibitors and motivations related factors to determine whether one can embrace the cloud services or not. Therefore, this paper presents a holistic and flexible cloud decision framework by taking a wide spectrum weighted factors related to the acceptance or denial of the cloud services. To have sustainable decision and obviating the shortcomings of the existing approaches on the cloud service adoption, a deep understanding of organisation's business process requirements and cost implications is required. To utilise the proposed model, the functional and non-functional requirements associated to the business process of an adopter organisation must be specified. To reach a concrete decision, a hybrid approach is applied by incorporating the analytic hierarchy process and Delphi methods to prevent subjective outcomes and to have diverse experiences at the same time. To support the decision model, some economic theories and Moore law are used. To verify the proposed model, a Telecommunication Company is considered as a case study for its 6-year plan of investment. The simulation results of conducted scenarios for the mentioned mid-scale case study prove that it is logical to establish on-premises a private datacenter and utilising the hybrid deployment once it encounters abrupt burst of resource demand. Altogether, the proposed holistic model can be customised for different users with different scales.

Modernizing cloud computing systems with integrating machine learning for multi-objective optimization in terms of planning and security

“…Hosseini Shirvani et al introduced an asset dispersion model that considers different asset valuations for several service providers and diverse asset allocations concurrently, resulting in increased benefits [7]. The analysis indicates that the evaluated cost closely aligns with the actual exchange cost, which is somewhat lower than the true value.…”

Tercerización de servicios de tecnologías de información: modelo de gobierno para las universidades públicas

“…Luego, vino la tercerización usada en el ámbito educativo con los almuerzos de los estudiantes, el transporte en autobús y los servicios de limpieza. Hoy en día es común tercerizar servicios para gestionar los activos de TI de las empresas con un proveedor de servicios en la nube (Hosseini Shirvani et al, 2022). Las empresas también tienen preocupaciones con respecto a la tercerización de servicios, y aunque la contratación externa obedece generalmente a una estrategia empresarial, surgen interrogantes a la hora de llegar a un acuerdo con el proveedor por la falta de consistencia en la calidad del servicio o el riesgo de perder el control sobre la administración de los servicios tercerizados, que pueden llevar a problemas como el despido de empleados, la falta de privacidad de la información o la pérdida de identidad empresarial, entre otras (Bates et al, 2021;Hammami et al, 2021;Zakaria y Mustaha, 2017).…”
