Reading books
Listening to podcasts
Going to their user groups and local events

As a result, testing, infrastructure as code, and just general DevOps were not a surprise.

10. Why?
After my first experience with configuration management at Stack Overflow, I knew that was going to be critical on Windows.
So I bet on DSC and PowerShell

This took me to Chef and gave me the platform I have today to share my thoughts with you.

12. Continuous Delivery for Infrastructure

13. “Common problems include:
Changes that often result in failures and are difficult to diagnose and fix.
Dev, test, and staging environments that are different from production environments, causing failures when builds are promoted across environments.
Lots of manual work required to deploy.
Lots of handoffs between teams, resulting in slow, inefficient deployments.”
- State of DevOps (2015)
Configuration management alone does not fix this

14. Consistency, Resilience, Repeatability

15. Serializing Tribal Knowledge and Intuition

16. Making All Environment Change Into Standard Change

17. What Does a Pipeline Look Like?

20. Components of a CI/CD Pipeline for Infrastructure

21. Source Control enables Peer Review and Change Tracking

22. “We found that when external approval (e. g
“We found that when external approval (e.g., change approval boards) was required in order to deploy to production, IT performance decreased. But when the technical team held itself accountable for the quality of its code through peer review, performance increased”
- State of DevOps (2014)
Peer review is more effective than Change management boards

23. “The benefits of version control shouldn’t be limited to application code; in fact, our analysis shows that organizations using version control for both system and application configurations have higher IT performance.”
- State of DevOps (2014)

24. Testing – Lint, Syntax, Unit, and Integration
