Difference between Devops and SRE

Previously, developers and operators were separated having different objectives.

DEV for Features
OPS for Stability

So Devops has appeared in order to:

  • Reduce Organization Silos
  • Accept Failure as Normal
  • Implement Gradual Change
  • Leverage Tooling and Automation
  • Measure Everything

SRE (Site Reliability Engineering) is class to implement Devops:

  • Share ownership of production with developers
  • Post Mortem approach after incident [avoid same failure to repeat]
  • Canary approach applying small % of change at the same time
  • Eliminate manual work as much as possible
  • Measure ROI and reliability
