Model-Based Migration of Legacy Software Systems into the Cloud: The CloudMIG Approach

Cloud computing supplies software, platforms, and infrastructures as a service (abbr. SaaS, PaaS, and IaaS, respectively) over a network connection. From a user's perspective, resource efficiency and scalability can be improved through aligning a cloud-based application with the cloud environment. Running an existing software system on a cloud computing basis usually involves extensive reengineering activities during the migration. We present identified shortcomings of current approaches and introduce our model-based approach CloudMIG for the semi-automated migration of enterprise software systems to scalable and resource-efficient PaaS and IaaS-based applications which addresses these shortcomings.
