For instance, If I have a very unpopular system, I may only allocate a couple servers to handle and process incoming traffic. When a software engineer builds an API, he or she provisions a certain amount of servers to satisfy the expected incoming demand. But the question is, why do applications rate limit their clients? Lets explore that below. So now we understand what throttling is as a concept. But either way, its important to understand who-does-what from the get-go as much of the remaining article assumes this knowledge. Throttling is a policy that the Server enforces and the Client respects.Ĭlients can respect this policy with certain policies such as Retries and Exponential Backoff (more on that later). One thing I want to emphasize here is the direction of the relationship between Client and Server when talking about Throttling. “Throttling, also sometimes called Rate Limiting, is a technique that allows a service to control the consumption of resources used by an instance of an application, an individual tenant, or an entire service” Source: I’m going to give you the important bits that are applicable in real world systems that I have worked with. In this article I want to help you understand throttling from a practical perspective. I find a lot of articles these days such as this one from Microsoft tend to over-complicate this very simple concept with an overload of detail. The concept itself is a fairly simple one: “just control the amount of traffic to an application”. Regardless if you’re trying to design a system to protect yourself from clients, or if you’re just someone trying to call an API, Throttling is an important thing to know about. These APIs apply a rate limiting algorithm to keep your traffic in check and throttle you if you exceed those rates. Its also important if you’re trying to use a public API such as Google Maps or the Twitter API.
