2. Azure API Management Rate Limit Policy

Azure API Management provides a rate-limit policy to prevent API usage spikes on a per subscription basis. Here is an example of implementing a rate limit policy in Azure API Management:

<inbound>
    <rate-limit calls="20" renewal-period="90" remaining-calls-variable-name="remainingCallsPerSubscription"/>
</inbound>

For more information, refer toAzure API Management Rate Limit Policy.

3. Cloudflare Rate Limiting Rules

Cloudflare's rate limiting rules allow you to define rate limits for requests matching specific criteria. These rules include parameters like characteristics, period, requests per period, and duration. Cloudflare offers both dashboard and API-based configuration for rate limiting rules.For detailed guidance on configuring rate limiting rules in Cloudflare, visitCloudflare Web Application Firewall (WAF) docs.
