Live site culture

Live site culture is the focus of an organization to prioritize the experience and reliability of the live site over everything else. A live-site culture promotes the idea that anything that happens in the production environment takes precedence over anything else. Next, anything that threatens production, is about to go to production, or hinders going to production at any time gets priority. Only when these are all in order is the attention shifted to future work.

• Live site first
• Control exposure through feature flags
• Make vulnerabilities real and personal
• Engineering is more than an ops partner
• Production telemetry is the heartbeat of your service
• Make alerts actionable
