Spring Boot working as a Technical Lead in the WSIT Wholesale IT Project, focusing on migrating Mule PCF APIs to Spring Boot with KONG Gateway. That’s a significant modernization effort—moving from MuleSoft on PCF to a microservices architecture with Spring Boot and an API gateway like Kong.

Migration Strategy

Assessment Phase

Identify all Mule APIs and their dependencies.

Document integration points, data formats, and security policies.

Check for custom connectors or Mule-specific features that need alternatives in Spring Boot.

Design Phase

Define the new architecture: Spring Boot microservices + Kong Gateway.

Decide on API versioning and routing strategy in Kong.

Plan for authentication/authorization (JWT, OAuth2, etc.) in Kong and Spring Boot.

Implementation Phase

Create Spring Boot services using REST controllers.

Use Spring Cloud for service discovery if needed.

Externalize configurations (Spring Config Server or Kubernetes ConfigMaps).

Gateway Integration

Configure Kong routes, services, and plugins (rate limiting, logging, auth).

Automate Kong configuration using Declarative Config or Kong Ingress Controller if on Kubernetes.

Testing & Validation

Functional and performance testing for APIs.

Validate security policies and error handling.

Compare response times and payloads with Mule APIs.

✅ Key Technical Points

Data Transformation: Mule often handles XML/JSON transformations easily; in Spring Boot, use Jackson or custom converters.

Error Handling: Implement global exception handling using @ControllerAdvice.

Observability: Integrate Spring Boot Actuator, Prometheus, and Grafana for monitoring.

CI/CD: Automate builds with Maven/Gradle and deploy via Jenkins, GitHub Actions, or Azure DevOps.
