What is scaling rate limiting and why is it important?

Scaling rate limiting is a technique used to control the number of requests a user can make to a service in a given time frame. It's important because it helps prevent abuse, ensures fair usage, and maintains the performance of the application.

How does rate limiting work in practice?

In practice, rate limiting can be implemented using various algorithms like Token Bucket or Leaky Bucket. These algorithms track the number of requests and allow or deny them based on predefined limits.

Can you give me an example of where rate limiting is applied?

Sure! A common example is in APIs, where a service might limit users to 100 requests per hour to prevent overload and ensure availability for all users.

What happens if a user exceeds the rate limit?

If a user exceeds the rate limit, they typically receive an error response, often with a status code like 429 Too Many Requests, indicating they need to wait before making more requests.
