Abstract At present, many open source softwares are developed in all parts of the world, e.g., Firefox, Apache HTTP server, Linux, Android, and so on. Open source software is now attracting attention as the next-generation software development paradigm because of the cost reduction, quick delivery, and work saving. We focus on a cloud computing environment by using open source softwares such as OpenStack and Eucalyptus because of the unification management of data and low cost. A cloud computing is attracting attention as a network service to share the computing resources, i.e., networks, servers, storage, applications, and services. We propose jump diffusion models based on stochastic differential equations in order to consider the interesting aspect of the provisioning process. Moreover, we formulate a total expected software cost based on the proposed jump diffusion model for the environment of cloud computing. Then, we discuss the determination of optimum software maintenance times minimizing the total expected software cost.
