“…The simultaneous cloud-interoperability decisions refer to the investment decisions for which both the variable for the cloud capacity and the variable for the interoperability enhancement are solved at the same time in the hope of reducing the total cloud costs synergistically. The cloud-interoperability evaluation and investment model is given as the total cost minimization function (7).…”

“…The hybrid cloud enjoys the benefits of both private and public clouds, but the combination of the two has introduced challenging issues such as data security, performance, and cost optimization [7]. According to RightScale's 2019 State of the Cloud Report [5], the hybrid cloud is the most preferred cloud for corporate cloud capacity investment.…”

While the rapid growth of cloud computing is driven by the surge of big data, the Internet of Things, and social media applications, an evaluation and investment decision for cloud computing has been challenging for corporate managers due to a lack of proper decision models. This paper attempts to identify critical variables for making a cloud capacity decision from a corporate customer's perspective and develops a base mathematical model to aid in a hybrid cloud investment decision under probabilistic computing demands. The identification of the critical variables provides a means by which a corporate customer can effectively evaluate various cloud capacity investment opportunities. Critical variables included in this model are an actual computing demand, the amount of private cloud capacity purchased, the purchase cost of the private cloud capacity, the price of the public cloud, and the default downtime loss/penalty cost. Extending the base model developed, this paper also takes into consideration the interoperability cost incurred in cloud bursting to the public cloud and derives the optimal investment. The interoperable cloud systems require time and investment by the users and/or cloud providers and there exists a diminishing return on the investment. Hence, the relationship between the interoperable cloud investment and return on investment is also investigated.
