Abstract—The international physics community has spent large efforts in the last decade to utilize different types of resources in their computing model, in order to increase the available computing power and involve more people and institutions in the activities. In this paper we present the work done to define and implement a set of common tools for integrating cloud computing resources into the computing framework of the Belle II, T2K and Hyper-Kamiokande (Hyper-K) experiments to produce Monte Carlo simulations and run user analyses. Starting with the virtual machine lifecycle tool VCYCLE, we create a custom setup able to support and manage the environment of the three experiments, then integrate the machinery into the DIRAC infrastructure of Belle II and in the GridPP DIRAC service used by T2K and Hyper-K. In order to expand the number of usable cloud infrastructures, we extended the software capability by integrating token based authentication in the Openstack module of VCYCLE. With this modification we are able to run Monte Carlo production jobs on the European Grid Infrastructure (EGI) Federated Infrastructure demonstrating the flexibility of implemented the solution.

Keywords—Cloud, high energy physics, Monte Carlo simulations.
