Whiteboard Architecture Scenarios & Trade-off Decisions
Introduction
Whiteboarding is a critical skill for any platform engineer. It is how you communicate complex ideas to both technical and non-technical stakeholders.
Core Scenarios
- Designing an Internal Developer Platform (IDP): How do you balance abstraction with flexibility?
- Global Multi-Region Deployment: Active-Active vs. Active-Passive databases.
- High-Throughput Log Aggregation: Managing costs while ensuring data retention.
Navigating Trade-offs
Every decision has a cost. When whiteboarding, always articulate:
- Cost vs. Performance
- Consistency vs. Availability (CAP Theorem)
- Build vs. Buy
Summary
The goal of whiteboarding is not just arriving at the right answer, but demonstrating how you think.
