3 methods for microservice communication

Microservice architecture involves building applications through a collection of loosely coupled, maintainable, and testable services that can be independently deployed, each solving or supporting a business problem. This architecture promotes productivity, speed, and autonomy among teams, contributing to its growing popularity. However, communication between microservices presents challenges that can undermine its benefits if not properly managed. The article explores three communication patterns: synchronous HTTP communication, which introduces coupling; asynchronous HTTP communication, which maintains loose coupling but adds complexity; and message-based communication, which uses a message broker to facilitate indirect service interactions. Additionally, an event-driven approach further reduces service coupling by having services react to events rather than direct messages, promoting even greater autonomy. While these patterns highlight the trade-offs between synchronous and asynchronous communication, they also emphasize the importance of considering coupling and development complexities in microservice architecture.
