An Empirical Analysis of Amazon EC2 Spot Instance Features Affecting Cost-Effective Resource Procurement
Cheng Wang, Qianlin Liang, Bhuvan Urgaonkar
Article No.: 6
DOI: 10.1145/3164538

Many cost-conscious public cloud workloads (“tenants”) are turning to Amazon EC2’s spot instances because, on average, these instances offer significantly lower prices (up to 10 times lower) than on-demand and reserved...

Disk Prefetching Mechanisms for Increasing HTTP Streaming Video Server Throughput
Benjamin Cassell, Tyler Szepesi, Jim Summers, Tim Brecht, Derek Eager, Bernard Wong
Article No.: 7
DOI: 10.1145/3164536

Most video streaming traffic is delivered over HTTP using standard web servers. While traditional web server workloads consist of requests that are primarily for small files that can be serviced from the file system cache, HTTP video streaming...

An Experimental Performance Evaluation of Autoscalers for Complex Workflows
Alexey Ilyushkin, Ahmed Ali-Eldin, Nikolas Herbst, André Bauer, Alessandro V. Papadopoulos, Dick Epema, Alexandru Iosup
Article No.: 8
DOI: 10.1145/3164537

Elasticity is one of the main features of cloud computing allowing customers to scale their resources based on the workload. Many autoscalers have been proposed in the past decade to decide on behalf of cloud customers when and how to provision...

RAPL in Action: Experiences in Using RAPL for Power Measurements
Kashif Nizam Khan, Mikael Hirki, Tapio Niemi, Jukka K. Nurminen, Zhonghong Ou
Article No.: 9
DOI: 10.1145/3177754

To improve energy efficiency and comply with the power budgets, it is important to be able to measure the power consumption of cloud computing servers. Intel’s Running Average Power Limit (RAPL) interface is a powerful tool for this...
