A Petri net-based decision-making framework for assessing cloud services adoption: The use of spot instances for cost reduction
A Petri net-based multi-criteria decision making framework to assess a cloud service against a similar on-premises service. Our framework helps IT managers choose between two such options, and can be used for any type of cloud service. We also propose a Petri net to model cost savings using the spot instances purchasing option in public clouds. Simulations showed that spot instances present a promising cost-saving option in the auto-scaling process, even for simple business applications using few servers.
