Rate limiting with Redis: An essential guide

Rate limiting is essential for managing traffic, preventing abuse, and ensuring fair access to resources. Redis is a preferred tool for implementing rate limiting due to its speed, reliability, and features. The choice of rate-limiting pattern, such as leaky bucket, token bucket, fixed window counter, sliding window log, or sliding window counter, depends on traffic patterns, precision needs, and resource constraints. Understanding these patterns and their trade-offs helps in building efficient, fair, and user-friendly systems.
