Abstract

I've used previous columns to discuss several quality-of-service (QoS) metrics, including response time, throughput, and availability, in the context of Web scalability. In most of my past discussions, though, I treated these metrics in isolation; here, I'll discuss how performance and availability are interrelated by using an Internet data center (IDC) as a motivating example. IDCs provide the means for geographically distributed Internet users to tap into other computers and applications.
