DOD Presentation V2

  1. 1. From Software Development Bootcamp to Junior DevOps Engineer Cookie Lanfear
  2. 2. Why • Diversity • Experience • Consider a non-traditional entry route into the field • Either for yourself • Or for your future colleague/ employee
  3. 3. Onboarding and Mentoring Apprentices with DevOps Culture - Mercedes Coyle video • Why hire an Apprentice? • You have a strong desire to mentor and grow a new engineer • Give back to the labour pool and tech community at large • You can teach them your way of doing things • They don’t yet have bad habits • Inculcate DevOps culture and collaboration from the start • New engineers bring with them infectious enthusiasm • Source:
  4. 4. Popular Psychology - Self Help/Motivation Binge • So Good They Can’t Ignore You - Cal Newport • Thinking Fast and Slow - Daniel Kahneman • Winners - Alastair Campbell • How To Have a Good Day - Caroline Webb • Grit - Angela Duckworth • Mindset - Carol Dweck • A Mind for Numbers (and Coursera Learning How to Learn course) - Barbara Oakley
  5. 5. Self Help/Motivation Binge “Why skills trump passion in the quest for work you love” Craftsman Mindset > Passion Mindset* *(when first starting to consider what you want to do for a job/ career) 
 It is important to eventually cultivate both.
  6. 6. Topics we covered at CodeClan 16 Week Software Development Bootcamp - Programming languages: Ruby, Java, JavaScript - Object-Oriented Programming - Working in teams: stand-up/emotional therapy, countless paired programming labs, Git - Introduction to algorithms, SOLID principles, RESTful APIs - Web applications with Sinatra, Express - Databases: SQL, SQLite, MongoDB - 3 projects: - 1. Ruby, SQL, Sinatra - 2. Java, IDEs, Android, SQLite - 3. Group Project: JavaScript, Express, Google Maps API - Learning from others way more experienced and knowledgeable than I was Friendship Pear Programming
  7. 7. Dramatic re-enactment in graph form of what I knew (or rather what I didn’t know and had to learn on the job) That I knew nothing* * I didn’t really know how much I didn’t actually know, and probably still don’t
  8. 8. What is DevOps??? DevOps (a clipped compound of "development" and "operations") is a software engineering practice that aims at unifying software development (Dev) and software operation (Ops). 
  9. 9. What is DevOps???
  10. 10. Resources, Books and Training Courses, Oh My. devops-transforming-linuxfoundationx- lfs161x
  11. 11. Resources, Books and Training Courses
  12. 12. A few cool projects I have been a part of • Simple things like AMI rotations • Terraform to create the AWS infrastructure to implement Blue-Green deployments • Monolith -> Microservices • Reusable Terraform Modules
  13. 13. A few cool projects I have been a part of
  14. 14. Hypothetical Lesson Plan for the first 6 months Reading List: • Open Guide for AWS • The Phoenix Project • The DevOps Handbook • Continuous Delivery • Sign up for Linux Academy and Safari Books Online
  15. 15. Hypothetical Lesson Plan for the first 6 months • Month 1 - just general on-boarding - write off anyway • Get through the necessary security training etc • Must feel comfortable with asking stupid questions • Read ‘The Phoenix Project’ • Have the DevOps Handbook and Continuous Delivery on hand to refer to and read once finished • Start own research as to what they want to learn • Try not to break anything, but it’s okay if you do • Start shadowing Mentor/colleague • Be exposed to the problems and questions that other people ask • Be involved with the general upkeep of services • learn simple task like rotating an AMI and deploying and testing through environments • As a team, documentation is very important for helping to on-board
  16. 16. Hypothetical Lesson Plan for the first 6 months • Month 2-3 • Start and aim to complete Linux Essentials from Linux Academy • Research the Cloud Computing Service of choice - ex. AWS • Continue shadowing and working with mentor, taking time to progress through Tuckman’s (1965) model of Team Development (Forming, Storming, Norming, Performing) to finish a major project • Deploy, learn more about Jenkins
  17. 17. Hypothetical Lesson Plan for the first 6 months • Month 4 • Work with mentor on a couple of simple projects - start to learn another tool to help with work Chef, Puppet, Terraform, Ansible, Docker etc etc • Month 5 - build on previous work and knowledge, learn another tool • Month 6 - finish another major project • Reward them with a shout-out to validate their existence • Be patient
  18. 18. What is DevOps? • A whole team working together through the full work cycle to design, create, implement, protect, monitor and deploy quickly and safely • Using whatever tools we can to solve other people’s problems • UPTIME • It’s not a person, an occupation or a team • A way of doing things that is business minded and factory inspired to improve the workflow of your team Culture
  19. 19. What is DevOps? • At this point I’m less concerned over the definition and I just want to do whatever it takes to be able to do my job well • Everyone has their own experiences and thus attribute different definitions
  20. 20. Things I still have to learn • EVERYTHING - I have so much more to learn and so far to go, but I think I will always feel this way • Gain better knowledge of current tools/skills set • Refresh knowledge of programming and programming languages • Pretty ‘Ops-centric’ at the moment • Get more involved in the ‘Dev’ side of things? • The next new shiny things • More Linux • Jenkins • Get better at documentation
  21. 21. Failures/Lessons • Trying to run before I could walk • Trying to learn Chef before I knew Linux • Sometimes you will read/do/look at something and it won’t make sense - you will need to learn and gain more context first • Searching online for help with DevOps problems is a lot harder - maybe less people to ask and answer questions, niche • Generally first time mentorship relationships don’t work out — but it’s for the best • Stay hungry (for knowledge) but be patient
  22. 22. The Future Continue learning, practicing and doing as much as I can GLA - Graduate Level Apprentice Heriot-Watt University The idea - build upon knowledge in a variety of contexts Ideal: Work-based projects tie into university course work I’m able to start university knowing what I want to do and what to focus on Get over social anxiety and just go to more tech meet-ups
  23. 23. Final Thoughts
  24. 24. Final Thoughts • “If I have seen further it is by standing on the shoulders of Giants” - Isaac Newton
