Pragmatic DevOps - How and Why

on YouTube ↗01h 01m

" summary

DevOps is framed as delivering continuous value through concrete practices: organize code by deployable unit, use infrastructure as code, separate deployment from release with feature flags, and prefer build once deploy many. The Microsoft Azure DevOps pipeline runs about 600 PRs/day and executes roughly 80,000 unit tests per PR to catch issues early. Other specifics: treat bugs as technical debt, use red‑green‑refactor, make production the ultimate test environment, deploy smaller changes to reduce risk, and measure outcomes for customer-focused decisions.
