What is DevOps?
5
Meaning of DevOps “by the book”
6
DevOps and Classic approach
• Communications quality
• Development/Operations/QA cycle speed
• Infrastructure confidence
• Responsibility in the team and beyond
• Goal and vision
7
Implementations
• For bigger companies Unified goal for distributed departments Shared management per project or per task A lot of direct communication
• For startups and small business One cross-functional team per project
8
Key components
• People and good habits
• Get things done (Agile and/or Lean)
• Automate all the things!
• Continuous delivery – 10 deployments per day should not be a problem
• Lean development (less resources delivered just in time)
9
People and habits
• Group of passionate people
• Set of good habits
• Habitual loops to introduce new ones
• Maintain and groom habits and surrounding tools
10
Get Things Done (development)
• Delivered working product is the ultimate goal
• The smaller the step, the easier is to revert one
• Solve a problem at hand or “right here, right now”
11
Automate (operations)
• Automate everything you can but not more
• Revisit automation periodically
• Treat your tools same way your treat your product
• Metrics
12
Deliver, review and repeat
• Smooth delivery process allows you to fix almost any problem in a timely manner
• More frequent deliveries gives you more confidence in your infrastructure
• More deploys = more features/bug fixes(theoretically)
13
Be closer to production
• Ideally team should be able to manage it's own infrastructure
• The closer your environment to production, the easier the twist
14
“Eat your own dog's food”
• First consumer of a product is the Team
• Fastest Feedback loop possible
• QA by usage
15
Lean resource usage
• Premature optimization is evil indeed
• Solve what is on the table right now
• Keep focus on what you are working on
