DevOps Roundup
What we’ve covered
Section titled “What we’ve covered”We laid the foundational philosophy needed before we start wiring up tools.
We’ve covered:
- DevOps as an approach to improving how software is built, shipped, run, and improved
- the old Dev vs Ops split and the friction between change and stability
- CI/CD and repeatable pipeline thinking
- Infrastructure as Code as a move away from memory-based setup
- immutable infrastructure as a way to reduce fragile manual patching
- observability as a way to understand running systems after deployment
- how these ideas apply even to a simple Node app, not just giant enterprise systems
The Real Finish Line
Software is not done when the code works on one machine. Professional software needs a delivery story, an environment story, and an operations story.
Suggested Discussion Prompts
Section titled “Suggested Discussion Prompts”- Why is “it works on my machine” not an acceptable finish line?
- What kinds of problems happen when setup lives only in someone’s memory?
- Why might operations teams resist constant change?
- Why is a repeatable build/deploy process more valuable than a clever undocumented one?
- Why do logs matter after deployment?
Checkpoint
Can you confidently answer the discussion prompts above? If not, review the previous pages. This foundation is necessary before we begin building Docker containers.

⏭ Time to Practice
Section titled “⏭ Time to Practice”This was the mental model lesson. Before we package the app in Lesson 02, let’s explore these concepts a bit deeper with an independent exploration lab to cement the foundation.
