Microservice Design Patterns Under 15 min | Service Discovery

Description

In this video, we explore the Service Discovery Pattern—a core design pattern in microservices architecture that enables services to dynamically find and communicate with each other. Complete code link in the 1st comment. Using a practical example with Order Service, Payment Service, and Shipping Service, we explain why hardcoding service addresses fails in distributed systems and how a Service Registry solves this problem. You’ll learn how services register themselves, how clients discover healthy instances at runtime, and why service discovery is essential for scalability, resilience, and cloud-native systems. This video is part of an ongoing Microservices Design Patterns series, where each pattern is explained in under 20 minutes with real-world examples and architectural clarity.
