  #2 Traditional approachvs DevOps
• 11.
  • Devs writecode • "throw it over the wall" to QA • Code bounces back and forth between Dev and QA as QA discovers problems and Devs fix them • Finally, it is ready for production The Story of Some Code: Traditional Approach
• 12.
  • Automation forAO is Crucial for streamlining workflows, reducing human errors and reduce the manual efforts. • Oh no! There's a problem. Ops throws it back over the wall to Dev • Each group's domain is a "black box" to the other groups • "Our systems are fine, it's your code!" • "But the code works on my machine!" Automation

  • DevOps cultureis about collaboration between Dev and Ops. • With DevOps, Dev and Ops work together and share the same goals. DevOps Culture
• 15.

• 16.
  • Devs writecode • Code commit triggers automated build, integration, and tests • QA can get their hands on it almost immediately • Once it is ready, kick off an automated deployment to production The Story of Some Code: DevOps
• 17.
  • Since everythingis automated, it is much easier to deploy while keeping things stable • Deployments can occur much more frequently, getting features into the hands of customers faster The Story of Some Code: DevOps (continued..)
