WSO2 Micro Integrator

Build Status License

WSO2 Micro integrator is a open-source, lightweight, fast, scalable, and distributed microservice integration layer which is the cloud-native distribution of WSO2 Enterprise Integration (EI)


Why Micro Integrator?

WSO2 Micro Integrator is built for developers who would like to integrate microservices and cloud native architectures using a configuration-driven approach. The Micro Integrator gives developers the best possible experience for developing, testing, and deploying integrations and tooling.

The Micro integrator developer experience is especially tuned for,

  • Integration developers who prefer config driven approach.
  • People who are looking for a solution to make their brownfield (ie. legacy systems) integrated into their new microservices based solutions.
  • Existing WSO2 EI and integration middleware users who want to move into cloud native or Micro services architecture.

The Micro Integrator also provides an enhanced experience for those using a container-based architecture and works natively on the Kubernetes ecosystem and it makes deployment with Docker a simple process. Following are the main design objectives for developing the Micro Integrator.

  • Lightweight and optimized runtime based on the same integration runtime of EI.
  • Native support for Docker and Kubernetes.
  • Flawless developer experience for developing, testing and deploying integrations and tooling.
  • Integrate natively with cloud native ecosystem projects.
  • Building a runtime suitable for hybrid integration requirements (integration cloud).
