API as a Microservice​

The approach outlined below is built on a core principle: all data extensions and enhancements occur exclusively at the back-end middleware level. This ensures the original API remains a true microservice: simple, stable, and immutable. Clients interact with the API to access core data, but the back-end middleware handles all business logic, data enrichment, and integration with external systems. This setup gives clients the flexibility to adapt and extend data to meet their needs without modifying the API itself.

KEY TAKEAWAY
This architecture emphasizes the principle of loose coupling between components. The API remains unchanged, regardless of changes in client requirements.
  • All extensions and custom logic are handled on the back-end middleware.
  • Middleware is responsible for:
    • Integration with external sources
    • Data enrichment and transformation
  • Each client has the freedom to configure middleware according to their specific needs.
WHY THIS MATTERS
This approach provides developers with full control over the data transformation process. The API stays:
  • Simple: Focused only on providing core data.
  • Reliable: Free from frequent updates or client-driven changes.
  • Independent: Unaffected by unique client-side requirements.

Advantages of API as a Microservice

We have separated the API into an independent microservice to simplify the integration process and enhance client experience:
  • Reducing Technical Burden: We take full responsibility for maintaining and evolving the API, relieving clients from the need to support complex technical solutions.
  • Modular Approach: The API is built using a microservice architecture, ensuring flexibility and ease of scalability.
  • Enhanced Functionality:
    • Analytics tools for data analysis.
    • Advanced statistical capabilities.
    • Regular endpoint updates to meet modern requirements.

​
What Does This Mean for Clients?​

  • Focus on Business Goals: Clients can concentrate on achieving their educational objectives without worrying about technical support.
  • Updatable Features: You gain access to a constantly evolving service that adapts to your needs.
  • Scalability: Easy integration enables seamless expansion of functionality in the future.
