This paper describes chosen aspects of the European Integrated Tokamak Modelling Task Force (ITM-TF) effort. It covers topics related to latest developments towards providing fusion scientists with a software framework for fusion modeling and simulation. The proposed framework provides researchers with an easy to use, workflow based environment for scientific computations. It allows the execution of various applications in numerous distributed computational resources directly from a user friendly, intuitive interface. We present the latest advances in the development of easy to use tools allowing the integration of the physics codes into the scientific workflows that schedule jobs to different infrastructures. The presented approach provides a simple way to access extensive computational resources and hides the complexity of the process at the same time. It allows for easy extension of existing simulation scenarios and fast prototyping. Some aspects of interactive communication between workflow environment and running jobs are discussed. Results of two practical use cases are presented in the context of the discussed workflow based solution: a parametric study and a plasma turbulence workflow.
