Monetary Cost-Aware Checkpointing and Migration on Amazon Cloud Spot Instances

Free registration required

Executive Summary

Recently introduced spot instances in the Amazon Elastic Compute Cloud (EC2) offer low resource costs in exchange for reduced reliability; these instances can be revoked abruptly due to price and demand fluctuations. Mechanisms and tools that deal with the cost-reliability trade-offs under this schema are of great value for users seeking to lessen their costs while maintaining high reliability. The authors study how mechanisms, namely, check-pointing and migration, can be used to minimize the cost and volatility of resource provisioning. Based on the real price history of EC2 spot instances, they compare several adaptive check-pointing schemes in terms of monetary costs and improvement of job completion times. They evaluate schemes that apply predictive methods for spot prices.
