Abstract
Amazon EC2 Spot Instances (SIs) create a
competitive low price computing facility. Spot prices are
typically far below on-demand prices, and this makes them
most suitable to lower the cost of tasks and potentially
execute them when there are many spot instances available.
However, using spot instances for potential cost savings is a
challenging task. The volatility of spot instances deteriorates
the QoS of users which in turn limits their usage and
escalates the complexity of cloud environment. The surge in
utility computing has introduced many trade-offs between
price, performance and recently reliability. This paper
presents vision and challenges in using spot instances.
