DevOps
DevOps is not a job title or a tools checklist. It is how product engineering and operations share ownership of change and reliability. These notes cover the concepts and practices that keep delivery fast without making production a gamble.
Topics
- What DevOps is for
Closing the gap between building and running software — outcomes over tool brands.
- Culture and shared ownership
You build it, you run it — blameless learning, on-call, and product ownership of production.
- Flow and feedback loops
Small batches, fast feedback, and continuous learning from build to production signals.
- Infrastructure as code
Declarative infra, reviewable change, and drift control — treating environments like software.
- Reliability and operability practices
Designing for failure — runbooks, deployments, capacity, and production readiness as engineering work.
- Platform engineering and paved roads
How internal platforms enable DevOps at scale without recreating a central bottleneck.
- Security in the DevOps loop
Shift-left without gate theater — secrets, supply chain, and shared responsibility for secure delivery.
- DevOps anti-patterns
Tool worship, ticket Ops, and other ways “DevOps” becomes a sticker instead of a practice.
