Résumé
This paper presents the development of a versatile software framework enabling the multiform and seamless evaluation of distributed systems: from fast and flexible simulation to actual system execution. The OpenStack datacenter resource management infrastructure is considered as the main entry point of the proposed framework. Since the technological bridge between OpenStack and systems in production already exists, we propose a similar bridge to the popular SimGrid distributed system simulator. This way, actual system resources, and abstract SimGrid system models can be managed uniformly from the OpenStack environment. This paves the way to the multiform design exploration of distributed systems.
