Event-Driven Order Processing System

A microservices-based order processing system developed in Go. The project demonstrates communication between services, retry mechanisms, and Dead Letter Queue (DLQ) handling using Docker.

Architecture

The system consists of three independent services:

• Order Service
• Payment Service
• Notification Service

Features

• Microservice architecture
• Event-driven communication
• Retry mechanism
• Dead Letter Queue (DLQ)
• Docker Compose deployment
• Independent services

Technologies

• Go
• Docker
• Docker Compose
