The GoDaddy Web Hosting Performance team
The GoDaddy Web Hosting Performance team is the group within GoDaddy that is responsible for tuning our web hosting environment for peak performance. In order to do so, we measure the response time of a control page loaded on every one of our web servers, every 5 minutes. An Application Index (APDEX) score is calculated for every server, which rolls up to product location, to product to product group. The Hosting Operations Center team has a prioritized list of servers to investigate if a performance issue arises. The company has great situational awareness of the performance levels of its products and services.
Every server has a “control site” that we use for performance monitoring. The control site is a WordPress page on Linux and a DotNetNuke page on Windows. A headless browser simulates a full page load of the control site on a regular basis. Time to first byte and full page load times, and many other interesting metrics, are pushed into graphite.
From the graphite API, an APDEX score is calculated on every server. Listed in table format, sorted by APDEX, the Web Hosting Operations Center team has a prioritized list of servers, updated frequently.
