-Petri nets require powerful tools to be executed for token game, visualizations, simulations, programming execution or analysis (verification and validation). Due to the non-recursive size of the state space of Petri net models in the general case in combination with dynamically growing and shrinking numbers of Petri net models have the need for scaling.

+Petri nets require powerful tools to be executed for token game, visualizations, simulations, programming execution or analysis (verification and validation). The state space of Petri net models can be of the size of non primitiv recursive functions. In combination with dynamically growing and shrinking numbers of Petri net models, like in reference nets, there is a strong need for scaling of simulation execution. RenewKube addresses this problem.
 
-RenewKube is a plugin for the Petri net tool [http://renew.de Renew]. It provides necessary technical frameworks for the design of large models. Embedding into virtual machines and Docker containers becomes easier. Starting from previous solutions with [http://renew.de Renew], Web Services, agent-based models, virtual machines and simple Cloud based implementations RenewKube integrates Docker and Kubernetes in its environment. It offers the scaling of the execution of complex models.

 RenewKube supports the installation and application of the frameworks and additional software enhancements for [http://renew.de Renew] by scripts and provides a lean interface for distributed simulations. Currently it is a prototypical proof-of-concept implementation, that inherits all basic necessary features for the distributed simulation support.

 On the one hand some software needs to be installed beside [http://renew.de Renew] and the RenewKube Plugin. With respect to the Petri net models it is also possible to control the scaling from within the Petri net models via two main commands getScale(); and setScale(<number>); inscriptions. These inscriptions are used in addition to the formerly developed DistributePlugin, which is considerably developed further for RenewKube. Starting from a first instance the simulation can grow in remote locations or within other local virtual machines. The Kubernetes Pod concept allows to loose containers at runtime. Up to now [http://renew.de Renew] model simulations on different machines were coupled in a stronger way, so that the whole simulation died when one of the nodes (the simulation running on a node) disappeared. However, this is an experimental features that will be tested in depth during the further development of RenewKube.
