The approach was first developed at Google in 2003.<\/p>\n<p>In an interview, Google vice president of engineering Ben Traynor said that the company hired 50-50 mix of people with backgrounds in both software engineering and system administration for its SRE teams. Google assigns small SRE teams to major projects. Traynor attributed Google&#39;s remarkable uptime to the automation of many site operations activities. While failures occasionally happen, they are fixed quickly because the SRE team has automated so many tasks beforehand.<\/p>\n<p>Google has also taken inspiration from role-playing games in the way that it has structured operation readiness drills to test engineers in the case of failures that do require automation. The company calls these exercises &quot;Wheel of Misfortune,&quot; where one employee plays the role of the system and one plays the role of the on-call engineer. Traynor said this approach engaged engineers to think about reliability more than conventional drills did.<\/p>\n<p>SRE is similar to DevOps, but the latter focuses on automating the deployment of systems generally, while SRE focuses specifically on reliability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Does Site Reliability Engineering Mean?
