Module 1 · DE Orientation for DevOps Engineers
A short bridge module. The goal isn't to teach Data Engineering from scratch — you've touched ETL and SQL earlier in your career. It's to re-orient that experience to modern cloud DE so the rest of the course lands faster.
Skill alignment
No direct skill requirement — this module is context bridging. It reframes what you already know (CI/CD, SQL, Linux, scripting) in the vocabulary the target role expects.
What we're assuming
- You've worked on an ETL/data-ingest pipeline at some point — know the shape of "extract from source, load, transform."
- You've written SQL against a database.
- You know Linux, cron, queues, logs — "scheduler" / "broker" / "job" concepts are natural.
What we emphasize given that background
- Skip: "what is a database," "how does SQL work," "cron 101."
- Emphasize: why columnar warehouses changed the economics, why ELT beat ETL in the cloud, why medallion/bronze-silver-gold became the dominant pattern.
- New: the utility-domain flavor (CIS, GIS, AMI, OMS) because this role is utility-specific.
