Zilla Order is a microservices-based order management system designed for scalability, flexibility, and experimentation with modern tools like Kubernetes, Kafka, and CI/CD pipelines.
This project currently consists of the following microservices:
| Service | Description | Database |
|---|---|---|
Inventory |
Manages product stock availability | PostgreSQL |
Order |
Handles order creation and validation | PostgreSQL |
Product |
Manages product catalog | MongoDB |
All services expose RESTful APIs documented via Swagger.
“In my Zilla Order project, which simulated a microservices-based e-commerce system, I used Kafka and RabbitMQ together, each playing a specific role.
RabbitMQ was responsible for queuing transactional tasks between services — like placing an order or updating inventory — where I needed guaranteed delivery with fast, isolated processing.
On the other hand, Kafka was used as an event backbone to log and monitor distributed events, like OrderCreated, ProductReserved, or PaymentConfirmed, making it easier to trace the entire lifecycle of a request across the system.
I implemented retry logic using Spring Cloud Retry, and for autoscaling, I containerized everything with Docker, orchestrated by Kubernetes, allowing the consumers to scale based on workload.”
