Being able to run and manage applications in different environments (especially in clouds) is an urgent requirement in industry. Such portability requires a standard language to define both, the structure of an application as well as its management behavior. This paper sketches the main ingredients of such a language and explains its underlying concepts. Next, the concept of linked compute units is introduced providing verifiability of the results of dataintense work. Considering human beings in this concept results in linked social compute units. The benefits of describing scientific applications by this concept are worked out. The resulting vision of being able to run in silico experiments everywhere and its supporting high-level architecture is presented.
