What is Rate Limiting?
Understanding Rate Limiting in E-commerce
Quick Definition
Rate limiting is a network security and performance management technique that controls the number of requests a user or system can make to an API or service within a specified time frame. It prevents abuse, reduces server load, and ensures fair resource allocation by setting maximum request thresholds that trigger temporary blocks or slowdowns when exceeded.
Understanding Rate Limiting
Core Principles of Rate Limiting
- •Protection: Prevents system overload and potential denial-of-service attacks
- •Fairness: Ensures equitable resource distribution among users
- •Performance: Maintains consistent system responsiveness and availability
Common Rate Limiting Strategies
Token Bucket Algorithm
Allows burst of requests while maintaining average rate limit, like filling and emptying a token bucket
Fixed Window
Resets request count at fixed intervals (e.g., 100 requests per minute)
Sliding Window
Tracks requests over rolling time windows for more granular control
Leaky Bucket Algorithm
Processes requests at a constant rate, discarding excess requests
Rate Limiting Implementation Examples
| Service | Typical Limits | Purpose |
|---|---|---|
| API Gateway | 100 requests/minute | Prevent API abuse |
| Login Attempts | 5 attempts/15 minutes | Prevent brute-force attacks |
| Payment Processing | 10 transactions/hour | Fraud prevention |
| Email Sending | 50 emails/day | Prevent spam |
Best Practices for Rate Limiting
- ✓Clear Communication: Return informative HTTP status codes (429 Too Many Requests)
- ✓Graceful Degradation: Provide alternative paths or retry mechanisms
- ✓Adaptive Limits: Adjust thresholds based on user behavior and system load
- ✓Logging and Monitoring: Track rate limit events for security analysis
