Modules
Each week pairs a short lecture with a lab using anonymized edge traces.
Edge topology sketches
Draw PoP hops, origin fallbacks, and cache boundaries before instruments go live.
Span literacy
Label attributes that survive multi-tenant workers without exploding cardinality.
Sampling with empathy
Protect rare failures while keeping ingest costs conversational with finance.
User-impact overlays
Join edge latency with conversion checkpoints for a single narrative board.
Alert phrasing
Write pages that invite action instead of panic during night rotations.
Studio showcase
Present a dashboard walkthrough to peers and refine based on feedback.
Learning outcomes
- Build a visibility map for one production edge service.
- Justify sampling ratios with measured loss of signal.
- Produce a weekly review slide that ops and product can share.
- Document known blind spots instead of hiding them.

Learner notes
“Module 3 on sampling paid for itself the first month. I still want more time on worker cold starts.”
★★★★☆
“Solid studio pace. The showcase rubric was clearer than most internal training packs.”
FAQ
Do I need OpenTelemetry experience?
Comfort with basic traces helps. We teach attribute design from first principles, but we do not cover installing collectors from zero for every vendor.
Is pricing charged on this website?
No. Amounts shown are informational. Enrollment is arranged through our contact form or phone.
What is a real limitation of this course?
We do not provide a hosted telemetry backend. You bring your own stack (or a sandbox), and labs assume you can export spans safely. Teams without any export path will need a prep week before week one.
Are sessions live?
Cohorts include two live clinics per week plus async labs. Recordings stay available for thirty days after the showcase.
