others Introduction devOps

What is DevOps?

• Def: breaking down the wall between developers and operations to allow more frequent and reliable feature shipping
• Traditional model:
  1. Developers write code
  2. Code is thrown over to Ops
  3. Ops deploy the code and handles its reliability
     • Issues:
       • Tension between Dev and Ops: Devs care about releasing new features vs. Operations care about maintaining the reliability of software
       • When the code crashes in production, the people handling the crash are not the ones familiar with the code
• DevOps solution is to get the Devs involved in the Ops process
  • Automated testing and deployment
  • Easy deployment rollback
  • Enhanced observability of code in production
