Enterprise information system migration to the cloud: Assessment phase

摘要

Cloud computing has made a revolution in the way in which IT services are delivered to organizations. For organizations, have an effective and efficient IS migration process is important to ensure a successful process. Certainly, several migration processes have been proposed but we notice the lack of a general and well detailed migration process that ensures cloud migration and integrates an economic model that increases the profits of the organization in terms of cost and performance. To fill this gap, we propose a cloud migration process which allows automating the cloud service selection and deployment by using the brokerage model. The broker will help the organization to select the cloud provider that meets its requirements, and manage the provisioning and the execution of cloud services. This paper will be dedicated to explain and detail the first phase of this process which is the assessment phase. This phase represents the basis of the whole process and has a very important role in the success of the migration project. The assessment phase will be applied in a concrete example based on the information system of the company Sigma Conseil.
