Beschreibung
The cloud computing (CC) paradigm is transforming the way Information Technology (IT)
services are provided by converting IT products into services. This modification allows the
delivery of IT services to end users in a way the customers stop purchasing products and
start purchasing services instead. The successful migration to this paradigm by an organization
requires a deep comprehension of its own IT as well as the dynamics of CC. To this
purpose, a framework aggregating the activities that must be undertaken in two groups, the
on premise and the off premise, was developed. The on premise group includes the actions
developed by the customer, such as the development of a strategy plan, the attainment of a
detailed definition of the organization processes and services and the definition of what to
migrate to the cloud. The activities developed with the support of the candidates and selected
CSPs are in the off premise group. This group encompasses activities such as the
providers services’, the details ‘identification of the technologies related to the implementation
of the organization processes into the cloud and the analysis of the conditions of
service level agreement and the contract.
Furthermore, there is already an extensive set of recommendations for IT management and
IT governance in general – such as the Information Technology Infrastructure Library
(ITIL) and the Control Objectives for Information and related Technology (COBIT) recommendations.
However, the field of CC remains poorly covered. Acknowledging this
state of affairs and adding the fact that CC is concerned with IT services, not to mention
the number of organizations using ITIL in order to manage their IT services, the fact that
ITIL is being recognized as a set of good practices, led to the decision of studying the
applicability of service management, namely ITIL, to the migration of IT services to CC.
The motivation of this study is related to the circumstance that organizations can take advantage
of the work already carried out, the information gathered and the management of
services when implementing ITIL. Additionally, if the customer and the supplier implement
ITIL, the communication between them is also improved. Accordingly, a framework
to migrate IT services, applications data and infrastructures to CC has been developed and
the processes of this framework have been mapped to the ITIL’s framework.
