Rate-limiting is a common strategy for safe guarding a server from potential DDoS attacks or sudden peaks in network traffic. Rate-limiting instructs the server to block requests from certain IP addresses that are sending an unusual number of requests to the system.
We can apply rate-limiting to both Nginx and HAProxy. Nginx runs on each end node hosting the service, while HAProxy serves as the load-balancer and distributes incoming requests among available nodes. This post describes how to rate-limit requests on both Nginx and HAProxy and shows how to whitelist IPs and rate-limit a single URL. The final section shows how to apply this configuration in Puppet.
