What are the different types of rate limiting?

Rate limiting is a technique used to control the amount of incoming requests to a server. The main types include: 1. Fixed Window: Limits requests in a fixed time frame. 2. Sliding Window: Allows a more flexible approach by counting requests in a rolling time window. 3. Token Bucket: Uses tokens to allow a burst of requests up to a certain limit. 4. Leaky Bucket: Processes requests at a constant rate, smoothing out bursts.

Can you explain the token bucket method in more detail?

Sure! The token bucket method allows a certain number of requests to be made in bursts. Each request consumes a token, and tokens are added to the bucket at a fixed rate. If the bucket is empty, requests are denied until more tokens are available.

What are the advantages of using rate limiting?

Rate limiting helps prevent abuse of services, ensures fair usage among users, and protects against DDoS attacks. It also helps maintain server performance and reliability.

Are there any downsides to rate limiting?

Yes, rate limiting can lead to user frustration if legitimate users are blocked during high traffic. It may also require careful tuning to balance between security and user experience.
