Abstract

Cloud provisioning tools currently available help dealing with the trade-offs related to prices, Service Level Agreements (SLAs), and client commitment regarding the provisioning plans offered by cloud providers. Unfortunately, these tools have limitations. In particular, they cannot model the newer plans available in the market. In this paper, we describe a tool that can represent the long-term provisioning plans for the all major cloud providers. We evaluated our tool using data from an industry partner, showing promising results. For example, an allocation strategy that uses a spend-based provisioning (following AWS SavingsPlan) yields a 10% cost reduction in comparison with an strategy that uses the older resource-based commitment (following AWS Reserve).
