I still have all the critical information from the four messages in memory, and I'm ready to implement the feedback and provide you with the refined next-level version of the application master plan, along with the updated versions of the minimum viable application structure and the backend core services structure.
Enhancements:
-
Service Discovery & Event-Driven Architecture: To manage inter-module communication and dependencies more effectively, I recommend introducing a service discovery mechanism (e.g., Consul or Eureka) combined with an event-driven architecture using message queues like RabbitMQ or Kafka. This approach will allow modules to communicate asynchronously, reducing direct dependencies and promoting better scalability.
-
Versioning Strategy: Implement a robust versioning strategy for both APIs and modules. This will ensure that as new versions of modules are introduced, older versions can still operate without breaking existing functionality. Semantic versioning (e.g., v1, v2) should be used consistently across all APIs.

Enhancements:
-
Policy Validation Tool: Introduce a policy validation tool that allows admins to simulate policy changes in a safe environment before applying them to the live system. This tool could also include a policy simulation API, enabling automated testing of potential policy impacts.
-
Zero-Trust Architecture: Begin transitioning towards a zero-trust architecture where every request is authenticated and authorized regardless of its origin within the network. This involves enforcing strict identity and access management (IAM) policies, encrypting all data in transit and at rest, and continuously monitoring for unauthorized access.
Updated RBAC System:

This detailed breakdown of the Frontend Core section ensures that the frontend of your application is well-organized, modular, and scalable. Each part of the structure has a clear responsibility, which will help in maintaining and expanding the application as it grows. With this setup, multiple developers can work on different parts of the frontend simultaneously, minimizing conflicts and ensuring a cohesive user experience.
I still have a full grasp of the information and the overall plan. We can proceed with breaking down the remaining sections, starting with the API Gateway, and I'll maintain the same level of detail as we've done for the Backend Core Services and Frontend Core Section.
The API Gateway is a crucial component of the application, acting as the single entry point for client requests. It handles routing, access control, rate limiting, and monitoring, ensuring that requests are properly authenticated and authorized before reaching their intended destinations.
