Rate Limiting.
Implement intelligent rate limiting that protects resources while accommodating legitimate traffic.
RATE LIMITING STRATEGIES
Rate limiting protects ABIS from overload and ensures fair resource allocation. Implement limits at multiple levels: per client, per user, per endpoint, and globally.
Token bucket algorithm allows burst handling while enforcing average rate. Tokens accumulate over time (up to bucket capacity) and are consumed by requests.
Communicate limits clearly. Include rate limit headers in responses (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset) so clients can self-regulate.
1000/h
Standard Tier
Default rate limit for basic clients. Sufficient for development and small applications.
10000/h
Premium Tier
Elevated limits for production applications. Requires approval and monitoring.
CUSTOM
Enterprise
Negotiated limits based on use case. Includes dedicated capacity and SLA.
