Cloud SaaS and Model Driven Architecture

Cloud computing is an emerging computing paradigm in which the resources such as processors, storage and software applications are provided as services, remotely over the Internet. The software applications in the cloud may be targeted on different platforms. As is evident, the software technologies are evolving constantly. But, as newer software technologies emerge the existing ones become obsolete and need to be replaced. Therefore, it becomes obligatory to adopt a software development methodology where the impact of technological advancements on software applications is minimal. Model Driven Architecture (MDA) is a software development approach where the models are the prime development artifacts. These models abstract the business functionality of the software system from its implementation on specific platforms. Automated tools are used for model-to-model and model-to-code transformations.
