Rate Limiting
Rate limiting is a technique used to control the rate of requests or data flow to a system, service, or API, preventing abuse, ensuring fair usage, and maintaining stability. It involves setting thresholds on how many requests a user, IP address, or client can make within a specific time window, such as per second, minute, or hour. This helps protect resources from overuse, denial-of-service attacks, and ensures quality of service for all users.
Developers should implement rate limiting to secure APIs and web services against malicious traffic, manage server load, and comply with usage policies in multi-tenant environments. It is essential in scenarios like public APIs, authentication endpoints, and payment gateways to prevent brute-force attacks, data scraping, and ensure equitable access. Learning rate limiting is crucial for building scalable and resilient applications that can handle high traffic without degradation.
