Migration Destination Selection Algorithm for Spot Instances using SPS

Amazon Web Services (AWS) provides its excess computing resources as spot instances. Although spot instances are cheaper than on-demand instances, they may be removed by AWS when demand increases for computing resources. Consumers need to judiciously select and prioritize those resources whose operations must avoid being interrupted. Although recently a spot placement score (SPS) is being provided as a measure of spot instance availability, few researches are using SPS. In this study, we propose an instance selection algorithm using it to select spot instances that reduce interruptions.
