Design Rate Limiter | High Level Design | Part 1

In this video, we start building a strong foundation for understanding one of the most important backend engineering concepts asked in System Design interviews: Rate Limiting. This is the Part 1 of the Rate Limiter HLD series where we cover: ✅ What is a Rate Limiter? ✅ Why Rate Limiting is important in scalable systems ✅ Functional Requirements (FRs) ✅ Non-Functional Requirements (NFRs) ✅ Interview approach for solving Rate Limiter HLD ✅ First design insights and architecture thinking ✅ How to think like an SDE-2 / SDE-3 engineer during interviews This video is designed for: Software Engineers Backend Developers System Design Interview Preparation SDE-1 / SDE-2 / SDE-3 candidates FAANG interview prep 🚀 In the next video, we will cover: Rate Limiting Rules Fixed Window Sliding Window Token Bucket Leaky Bucket Distributed Rate Limiting Algorithms Production-grade design decisions If you enjoy backend engineering, scalable systems, LLD/HLD, and interview preparation content — make sure to subscribe 🔥 #SystemDesign #RateLimiter #HighLevelDesign #BackendEngineering #HLD #ScalableSystems #SoftwareEngineering #FAANG #SDE2 #SDE3 #Microservices #DistributedSystems #InterviewPreparation
