Rate Limiting vs Throttling in AWS: API Gateway, Lambda & Kinesis Explained

Most engineers use "rate limiting" and "throttling" interchangeably — but they're fundamentally different, and confusing them means you'll fix the wrong thing at 2am.

In this video I break down the real conceptual difference, then walk through two AWS architectures where both patterns play out in practice.

📌 WHAT YOU'LL LEARN
→ The exact difference between rate limiting and throttling (with a one-line rule you'll remember)
→ How API Gateway Usage Plans, stage throttles, and account limits work — and which layer hits first
→ Why your Lambda Authorizer can silently become a bottleneck (and the fix)
→ How to use reserved concurrency as both a floor and a ceiling
→ Why the IoT architecture deliberately embraces throttling rather than fighting it
→ What happens when DynamoDB write capacity is exceeded mid-burst
