What is devops?

DevOps is the union of people, process, and technology to enable the continous delivery of value to customers

Key metrics for successful development
- Throughput
  - Lead Time – from concept to deployed
  - Deployment Frequency – how frequent new code is deployed
- Stability
  - Change Failure – how often a deployment breaks some thing
  - Time to Restore – how quickly to recover from broken (either fix or revert)
  - Availability – how often service is good and available to be consumed
Grouping Performers (4.5 groups)
- Elite Performers
  - Deploy On Demand, lead time < 1hr, time to restore < 1hr, fail rate 0-15%
- High Performers
  - Deploy 1hr > 1dy, lead time 1dy > 1wk, time to restore < 1dy, fail rate 0-15%
- Medium Performers
  - Deploy 1wk > 1mth, lead time 1wk > 1mth, time to restore < 1dy, fail rate 0-15%
- Low Performers
  - Deploy 1wk > 1mth, lead time 1mth > 6mth, time to restore 1wk < 1mth, fail rate 46-60%
  - Misguided Performers
    - like Low Performers but better fail rate 16-30%
    - have often achieved better results by going slower, but platues with increased friction
- Elites vs Low,
  - 46x More Deployments, 7x Fewer Change Failures
  - Elites get to spend 50% on new work, low only 30%
  - Everyone spends 20% on unplanned work and rework
How to Improve
- Understanding the 3 ways
  - The First Way: Systems Thinking, Work Flows Downstream
  - The Second Way: Amplify and Shorten Feedback Loop, Downstream info effects upstream work
  - The Third Way: Culture of Experimentation and Learning
- The Technical Pracices of DevOps
  - Trunk-Based Development
  - Deployment Automation
  - Loosely Coupled Architecture
  - Continous Integration
  - Continous Testing
  - Monitoring & Observability
  - Managing Database Changes
  - Proactive & Reactive Integrated Security
