Adaptive Rate Limiting
Quick Reference
What & Why
Definition
>= 80% of public APIs have adaptive rate limiting protecting against traffic spikes and abuse.
Business Value
Improves system uptime from 99.5% to 99.9% and reduces blast radius of failures by 70% through circuit breakers and chaos engineering validation Achieving >= 80% APIs have rate limiting is a key milestone toward this goal.
Context
This capability is part of the Acceleration milestone's focus on scale automation, embed compliance, improve speed & reliability. Essential for teams targeting MTTR, CFR improvements.
Success Criteria
>= 80% APIs have rate limiting
Measurement
Rate limit config coverage + effectiveness metrics
Evidence
- Rate limit policies
- Throttling event logs
- Traffic spike handling reports
In Practice
Real-World Implementation
Teams configure API gateway rate limits: 100 req/min per user, 1000 req/min per API key. Adaptive: increases limit during normal load, strict during spikes.

Troubleshooting & FAQs
Common Issues
Issue: Target metric not improving
Solution: Verify measurement is accurate, check if prerequisites are fully implemented, review evidence artifacts for completeness
Issue: Team resistance to adoption
Solution: Start with pilot team, demonstrate value with metrics, provide training and support during transition
Issue: Inconsistent implementation across teams
Solution: Create shared templates and guidelines, establish regular sync meetings, use automation to enforce standards
Frequently Asked Questions
Can we implement this before completing prerequisites?
While possible, it's not recommended. Prerequisites ensure foundational practices are in place, making this capability more effective and easier to adopt.
How long does implementation typically take?
Most capabilities can be implemented within 90 days when tackled as part of the Acceleration milestone. Individual timelines vary based on team size and existing practices.
