People• Developers• Sysadmins• QA Testers• Network / Database / Storage administrators• Product / Sales / Marketing• Customers It’s about WHO and HOW

Culture• Collaboration• Communication• Sharing• Trust• Respect• Fail management

Share Culture• Tech talks / Standups / Hackatons ...• Production info exposed to developers• Share common metrics• Job swaps / Mixed teams• Explain your work• Care about others’ work

Fail Culture• “Things may break. Accept it.”• “Fail early, blame slowly.”• “Learn from mistakes, and everything else”• “Fail together”• “Responsibility in the right place”

Processes• Continuous delivery• Version control• Test driven operations Automation Agile methodologies

Tools• Conﬁguration Management• Logs intelligence• Monitoring• Trending & Data Visualization• Tests and Continuous Integration• (Continuous) Deployment
