Rackspace Cloud Servers versus Amazon EC2: Performance Analysis » The Bitsource: System Administration – Software Engineering – Web Application Development

Link To Full Story: www.thebitsource.com

The Bitsource conducted a review of the two cloud computing platforms, Rackspace Cloud Servers and Amazon Elastic Compute Cloud (EC2), to get a general idea of overall system performance. Included in the tests were pure computing power (CPU), and raw disk I/O throughput. Using a consistent testing methodology across most instance sizes over a two-month time span (a painstaking process requiring lots of patience) has resulted in the following comparison of CPU performance, disk performance and cost between the two platforms.

We hope that this evaluation will save the reader some effort by answering questions about how the two platforms compare in terms of time, power, efficiency and cost. The purpose of this article is to answer a simple question: How do the two platforms stack up against each other in terms of disk and CPU efficiency?
