You’re in a backend interview.
They ask:
“Design a globally distributed configuration propagation service that pushes config updates to tens of thousands of servers within seconds, with versioning, rollback, and strong delivery guarantees.”
Here’s how to approach it:
Start by clarifying the core requirements:
- Config changes must propagate worldwide within seconds
- Strong versioning and atomic rollout per region
- Rollback must be instantaneous
- Agents must validate the integrity and signature of configs
- Updates must be durable, auditable, and conflict-free
