Global vs. Per-Service Rate Limiting
Understand the differences and interplay between global rate limits applied at the edge and specific limits for individual microservices.
Global vs. Per-Service Limits
APIs often handle diverse traffic, from general users to specific internal systems. To manage this, we need different rate limiting strategies.
Today, we'll explore two key approaches: global rate limiting and per-service rate limiting. Understanding their differences helps build robust and fair APIs.
Guarding the Gates Globally
Global rate limiting is applied at the very edge of your system, before requests even reach individual services. Think of it as a bouncer at the club entrance.
- It protects your entire infrastructure.
- Often implemented in API Gateways, load balancers, or edge proxies.
- Focuses on overall request volume to prevent system overload or DDoS attacks.
