Developers Operations The Wall of Confusion 5. Developers Operations The Wall of Confusion Deployments 6. From: Ops To: Dev So we only just noticed your deployment request but you ticked the wrong box on the change form so now youre at the back of the queue and anyway it wouldn't have happened because there isnt enough time because of patching which is important work not like your dumb change which is probably buggy anyway so try resubmitting your ticket again and well take another look during the next deployment window. Maybe. PS LOL 7. Enter DevOps: Change of mindset Integrate teams, collaborate Automate as much as possible (everything!) Monitor and prole 8. DevOps Version control Automate infrastructure builds and deployments (Dev should be more like prod!) Automate testing of code Log, measure systems performance and optimise it 9. Benets of DevOps Faster time to market Respond to customer needs Better quality of releases and services Ability to scale infrastructure.. the Cloud!! Infrastructure as code! 10. Yeah but Hard to change culture Existing processes will need completely rewriting Imaginary utopia, not Real IT Risky - what if we automate everything and completely f**k up 11.
