Go E-Commerce Microservices

Overview#

A cloud-native e-commerce application implementing a microservices architecture in Go. The system demonstrates separation of concerns with optimized data storage per service, distributed caching, and asynchronous communication patterns.

Technical Details#

Service Architecture#

• Cart Service with Redis caching
• Catalog Service with PostgreSQL
• Checkout Service
• Payment Service
• Shipping Service
• Email Notification Service
• API Gateway (KrakenD)

Data Management#

• Redis for shopping cart state
  • Fast data access
  • Distributed caching
  • Session management
• PostgreSQL for product data
  • Full CRUD capabilities
  • Optimized indexing
  • Search functionality

Communication Patterns#

• RabbitMQ message broker
• Asynchronous event handling
• Publish/Subscribe model
• Event-driven workflows
• Service decoupling

Infrastructure#

• Docker Compose orchestration
• API Gateway routing
• Service discovery
• Load balancing
• Container management

Implementation Results#

The system achieved significant milestones:

• Scalable microservices architecture
• Optimized data access patterns
• Reliable event processing
• High availability design
• Maintainable codebase
