While often used interchangeably, there are subtle differences: Rate Limiting:
Hard limits on requests within a time window
Typically rejects requests that exceed the limit
Binary approach: allow or deny Throttling:
Controls the rate at which requests are processed
May delay requests rather than reject them
Can introduce artificial delays to smooth traffic Example: Rate limiting returns HTTP 429 when limit exceeded, while throttling might queue requests and process them at a controlled pace.
