Cloud Connectivity
Device-to-Cloud Contracts Workshop
Schema design, versioning, and shadow document patterns that keep firmware and cloud teams aligned.
Format: Bootcamp · Level: Foundational · Duration: 3 weeks
Tuition (informational): 540,000 KRW
Lead mentor
Evelyn Cho
Ex-platform engineer for smart appliances; champions boring JSON and explicit defaults.
Overview
Misunderstood JSON fields cause more outages than clever algorithms. You practice additive schema changes, compatibility gates in CI, and shadow documents that firmware can trust when offline. Labs include contract tests that fail loudly before bad payloads reach staging.
What is included
- JSON schema diff exercises
- Shadow merge strategies with mentor review
- Contract tests wired into sample CI
- Topic naming conventions for multi-tenant fleets
- Backfill playbook for renamed fields
- Error taxonomy workshop
- Role-play design review with cloud counterpart
Outcomes
- Ship a versioned schema with migration notes
- Demonstrate a failing contract test that guards a breaking change
- Publish a shadow reconciliation note for firmware peers
Participant notes
-
Shadow merge lab saved us from another silent field rename. Contract tests are now mandatory on Device-to-Cloud Contracts alumni repos.

Examples lean on vendor-neutral patterns; you can map exercises to AWS IoT Core or Azure IoT Hub with mentor office hours.
