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: Similar to fixed, but allows for more flexibility. 3. Token Bucket: Allows bursts of traffic by using tokens. 4. Leaky Bucket: Smoothens out bursts by processing requests at a constant rate.

Can you explain the token bucket method in more detail?

Sure! The token bucket algorithm allows a certain number of requests to be processed at once. Tokens are added to the bucket at a fixed rate, and each request consumes a token. If the bucket is empty, the request is denied. This allows for bursts of traffic while still enforcing an overall limit.

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 avoid impacting user experience.
