Create Node.js Express API server with a single “hello world” endpoint.In our mini-project for this article, we’re going to walk through a basic use case: Kong Gateway with the Rate Limiting plugin protecting a simple API server.
If you’re interested in rate limiting for Kubernetes services, check out this video: Or, perhaps only your premium users get unlimited API requests, while your free-tier users only get a hundred requests an hour.
#BZFLAG TIME LIMIT PLUGIN CODE#
Sometimes, it’s somebody else’s buggy code that hits your API endpoint 10 times a second rather than one time every 10 minutes. You want to safeguard your server from DDOS attacks.īut it’s also vital to limit non-malicious requests. You want to stop scrapers from slurping up your content. Yes, you want to shut down a bot that’s trying to discover login credentials with a brute force attack. You’re not only guarding against malicious requests. By restricting the number of similar requests that can hit your server within a window of time, you ensure your server won’t be overwhelmed and debilitated. Rate limiting is a defensive measure you can use to prevent your server or application from being paralyzed. Rate limiting is remarkably effective and ridiculously simple. Let’s take a step back and go over the concept of rate limiting for those who aren’t familiar. Rate Limiting: Protecting Your Server 101 This tutorial will walk through how simple it is to enable rate limiting in your Kong Gateway. You can configure the plugin with a policy for what constitutes “similar requests” (requests coming from the same IP address, for example), and you can set your limits (limit to 10 requests per minute, for example). The Kong Gateway Rate Limiting plugin is one of our most popular traffic control add-ons.
