What architectural model would you apply for developing a new software product?

The choice of architectural model depends on project requirements, scalability, support, and other factors. For a new software product, the following architectural approaches are often used:

• Layered (n-tier) architecture — separation into layers (presentation, business logic, data access), which simplifies maintenance and development.

• Microservices architecture — breaking the application into independent services, which increases scalability and allows parallel development of components.

• Event-driven architecture — interaction between components through events, suitable for systems with asynchronous processing.

• Clean Architecture — focus on separation of concerns and independence of business logic from external details.

For most new Java applications, a microservices architecture using Spring Boot and containerization (Docker) is often chosen, providing flexibility and scalability.

Example: if the product involves high load and frequent updates of individual modules, microservices are preferable. If the project is small with simple logic, a layered architecture is sufficient.
