2. I sometimes hear, “But Josh, I’m a developer, I don’t need to know that kind of thing.”
3. You are likely already doing some amount of Operations.
4. >>> Operations == Systems Administration False
5. Basically, Operations encompasses everything needed to run and maintain, that is, to operate a service in production.
6. That’s right, I’m telling you that most sysadmins are doing more than just typing commands into a terminal and writing shell scripts.
7. ITIL isn’t the devil, but the way people implement and use it makes it seem that way.
8. “But, Josh, do we need to do Ops if we run our application on a PaaS like Heroku?”
9. Yes. Yes.
10. A thousand times yes.
11. The decision to use a SaaS/PaaS/IaaS is an operational decision. By making it, you are doing operations.
12. If your build breaks when GitHub goes down, that’s on you, not on them.
13. NoOps is kind of a misnomer. It’s less that nobody does Ops, and more that everybody is responsible for aspects of that work.
14. Story Time
15. At the end of the day, if everyone your service touches is happy with how things are working, you’re doing alright.
16. Where does DevOps fit into all of this?
17. Tools and techniques are of course important to all of this.
18. Choosing what tools/techniques to use is a good portion of the battle.
19. Infrastructure as Code
20. Treat your Infra code as if it were any other code you’d write.
21. Config Management (Major options written in Python are Ansible and Salt)
22. In lieu of trying to cover an entire field in a short span, how about you ask me questions about what you want to know and I’ll answer them as best I can.
