摘要：Cloud computing is a computing model that provides computing resources on demand and charges only for the required and consumed resources (i.e., pay-as-you-go pricing model). Moreover, this computing paradigm leverages from most benefits such as high scalability, reduced IT costs, self- service on demand, and pay-as-you-go price models, that increasingly attracted the interest of the corporate world. Despite these attractions, in practice many organizations have found it difficult to adopt cloud-based solutions, particularly when faced with the need to migrate existing legacy applications to this new environment. One of the main obstacles faced by those organizations is the lack of a structured and general process to help application developers in selecting methods, tools and solutions for migration. For this purpose, this paper presents a structured and achromatic process for legacy migration to cloud environment. The process relies on a clear and simple step-by-step approach for migration operation and also introduces tools and techniques which can be applied in every step. Moreover, in this paper business model and scalability are considered.
