Why Abp Framework with projects using Microservice, with each Service having a No Layer structure instead of using an N Layer structure?

    In ABP Framework microservice projects, each service often uses a "no layer" (single-layer) structure instead of a traditional N-layer (multi-layer) structure for several reasons:

    1. Microservice Simplicity: Each microservice is designed to be small, focused, and independently deployable. Adding multiple layers (like Application, Domain, Infrastructure, etc.) can introduce unnecessary complexity for services that handle a limited scope.

    2. Reduced Overhead: Many microservices are simple CRUD or integration endpoints. The overhead of maintaining strict layering is not justified for such straightforward logic.

    3. Faster Development: A single-layer structure allows for faster iteration and easier maintenance, especially when the service is not expected to grow significantly in complexity.

    4. Deployment Independence: Microservices are independently deployed and versioned. The boundaries enforced by N-layer architecture in monoliths are less critical when each service is already isolated by process and API.

    5. ABP Support: ABP provides both layered and single-layer templates. For microservices, the single-layer template is recommended to avoid boilerplate and keep the service lightweight.

    6. Best Practice in Microservices: Industry best practices suggest keeping microservices as simple as possible. Layered architectures are more beneficial in large, monolithic applications where separation of concerns is critical.

    If a microservice grows in complexity, you can still refactor it into a layered structure as needed.

    hi

    Microservices are applications, not a DDD module.

    THanks.
