Increasing Spot Instances Reliability Using Dynamic Scalability

Traditionally, Infrastructure as a Service (IaaS) providers deliver their services as Reserved or On-demand instances. Spot Instances (SIs) is a complementary service that allows customers to bid on the free capacity at the provider data centers. Therefore, the decrease in the free capacity may result in terminating instances abruptly. To ensure fair trading, the provider does not charge customers for the interrupted partial hours. However, SIs price history traces analysis shows that uncharged time could rise up to 30% of the instance total run time, which means a reduction in the provider's profit.
