19. Tactical
20. Tactical: Operating the DevOps pipeline • A build break seems to be caused by an application code change: ◦ Which files were updated since the last build? ◦ Who all made the change(s)? ◦ What change(s) caused this break? ◦ Postulate on what the fix could be, if possible • Debug the ~5000 lines of legacy build script to understand it and figure out where to add the new functionality?
21. Tactical: Maintaining the pipeline • You’re a Java background and the Build System you’ve been asked to work on is .Net! Or iOS and Android !!!
22. Tactical: Continuous Automation • Automation in legacy or Packaged technologies where modern DevOps tooling is not very mature yet: ◦ Mainframe ◦ SFDC ◦ ERP ◦ Etc.
23. Operational
24. Operational • Onboarding a Project onto a DevOps pipeline: ◦ Our process works great - I don’t need all this change ◦ I have no idea on how these build/deployment scripts work? The guy who wrote these retired last year • Automation of Envt. Mgmt./Infrastructure ◦ Reverse engineer to creating BoM (Bill of Material) of an Environment or Infrastructure ◦ Lack of technical skills!
25. Strategic
26. Strategic • Scaling DevOps capabilities across Enterprise ◦ Creating the Business Case (ROI) for DevOps ◦ Work with Business and get funding for Project • Setting up a DevOps capability ◦ I work across 5 geo’s and 8+ Vendors. How to I make this work?

DevOps Engineer Senior DevOps Engineer DevOps Architect • Maintaining a DevOps pipeline • Fixing a Build Break • Continuous Automation (Envt/Infra) ✓ Good place to put the fundamentals in place. ✓ Ideally, spend a couple of years and gain as much depth of experience as possible • Creating a DevOps pipeline • Onboarding a Project onto DevOps pipeline • Continuous Automation (Envt/Infra) ✓ Good place to cement the fundamentals. ✓ Work in a start-up if possible. Gives a broader perspective on thigs, with a great deal of responsibility. • Setting up a DevOps capability • Creating a DevOps pipeline • Training ✓ Time to start adding real depth & width to the skillsets ✓ More the variety of tech stacks architected, the better!

33. • Consultant who has architected multiple Enterprises • OCM with new R&R creation • Enterprise structure for multi-speed IT Evangelist
36. Fresher or <5 years experience • Learn about Code Review, Static Code Analysis tools etc. and implement these in your DevOps pipeline • Do *not* target a DevOps Engineer’s profile to start with • Be a great Developer (language / tech does not matter) • Live the "pain of the SDLC" Leaning towards DevOps Your boundless enthusiasm to change the world is your strength!
37. Operations expert Have you? o Worked with one scripting language and automated stuff? o Had practical exposure with Testing tools? o Liaised with Dev teams and debugged Production issues? o Been an expert in monitoring and feedback tools? o Sought/built DevOps solutions for your team? You know how to take stuff into Production. And how to maintain infra. And how not to!
38. Operations expert You know how to take stuff into Production. And how to maintain infra. And how not to! Learn a Continuous Integration tool like Jenkins/Azure DevOps etc. and automate your build/deployments Learn a Configuration Management tool like Chef/Puppet/Ansible and automate the infrastructure provisioning Application side of Ops Infrastructure side of Ops Learn the Cloud native equivalents for the same – E.g. OpsWorks on AWS etc. If your Organisation in on a Cloud journey… Learn the PaaS/Container/Serverless Cloud native equivalents for the same – E.g. CodeBuild, CodeDeploy on AWS etc.
