# Ecommerce Microservices Application in Kotlin
## Architecture Diagram
## Microservices Architecture Design Patterns
In this project, I have implemented several design patterns commonly used in microservices architecture
| Design Pattern | Tools | Description |
|-----------------------------------|----------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------|
| **Service Discovery** | [Spring Cloud Netflix](https://spring.io/projects/spring-cloud-netflix) | Service discovery automatically detects services for communication without relying on hardcoded addresses. |
| **API Gateway** | [Spring Cloud Gateway](https://spring.io/projects/spring-cloud-gateway) | Single entry for managing, routing, and securing requests between clients and services. |
| **Circuit Breaker** | [Resilience4j](https://resilience4j.readme.io/docs) | Prevents cascading failures by stopping repeated requests to a failing service and allowing it to recover. |
| **Distributed Messaging System** | [Apache Kafka](https://kafka.apache.org/) | Asynchronous communication between services in microservices environment. |
| **Transactional Outbox Pattern** | [Scheduler](https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/Scheduled.html) | Resolves the dual write problem by storing messages in an outbox table, ensuring consistency with business data. |
| **Event Inbox Pattern** | [Inbox Database Table](https://softwaremill.com/microservices-101/#inbox-pattern) | Processes incoming events by storing them in an inbox table, ensuring idempotency and consistency. |
| **Distributed Scheduler Locking** | [ShedLock](https://github.com/lukas-krecan/ShedLock) | Ensures only one instance of a scheduled task runs across multiple parallel application instances. |
## Security Testing Topics
I have implemented below security testing automation pipelines
| Security Topic | Tools | Implemented Pipeline |
|--------------------------------------|-----------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------|
| Static Application Security Testing | [OWASP dependency-check](https://jeremylong.github.io/DependencyCheck/index.html) | [Service Vulnerability Scanner](.github/workflows/service-vulnerability-scanner.yaml) |
| Static Application Security Testing | [Trivy Docker Image Scanner](https://trivy.dev/) | [Service Docker Image Scanner](.github/workflows/service-image-vulnerability-scanner.yaml) |
| Static Application Security Testing | [Kubescape](https://github.com/marketplace/actions/kubescape) | [Kubernetes Security Scan](.github/workflows/kubernetes-security-scan.yaml) |
| Dynamic Application Security Testing | [OWASP ZAP Scanner](https://www.zaproxy.org/) | [Service DAST Scanner](.github/workflows/service-dast-scanner.yaml) |
