Web 2.0 applications place new and different demands on servers compared to their Web 1.0 counterparts. Simultaneously, the definitive arrival of pay-as-you-go “cloud computing” and the proliferation of application development stacks present new and different degrees of freedom in deploying and tuning software-as-a-service. We first identify non-obvious challenges and caveats to performing “apples-to-apples” comparisons of Web 2.0 application deployments. We then offer Cloudstone, a toolkit consisting of an open-source Web 2.0 social application (Olio), a set of automation tools for generating load and measuring its performance in different deployment environments, and a recommended set of constraints for computing a metric we believe makes more sense, dollars per user per month. By way of example we present preliminary measurements of both Rails and PHP versions of Cloudstone on a variety of Amazon Elastic Compute Cloud (EC2) configurations, discussing the challenges of comparing platforms or software stacks and how Cloudstone can help quantify the differences.
