Data and process abstractions for cloud computing

Applying suitable application models is essential to achieve efficient execution of the applications, effective development process and assure application portability and reusability. We observe that execution environments and the cloud environment in particular, lack of tools that would make it more available from a programmer perspective. Complexity and variety of libraries and authentication methods do not correspond with simplistic functionality of those services. We approach this issue at several fields - workflow systems, domain specific languages and cloud computing. Our work focus on two points, optimizing existing application models by supplementing them with additional tools and providing new features, and develop new models that are based on our research on applications in the cloud environment.
