Hi welcome to the I aced my interview series! In this video we are going over microservices design patterns by starting with a simple server then scaling it up. 

This is going to be a 3 part series:
1. microservices design 
2. api design 
3. database design

Timeline:
00:00:00 - Intro
00:00:15 - Background 
00:01:18 - Service Split
00:02:38 - Service Discovery + LB
00:04:40 - Event Driven
00:06:38 - Monitoring / Error Handling
00:11:25 - Ending

A walkthrough of core microservices design patterns using an e-commerce platform as a running example. Covers the motivation for splitting a monolith, database-per-service pattern, service discovery (client-side vs server-side), load balancing algorithms, synchronous vs asynchronous communication (REST vs message brokers like Kafka), resilience patterns (circuit breaker, exponential backoff with jitter, idempotency keys), and observability through centralized logging with trace IDs and distributed tracing tools like Jaeger.
