 Application architecture provides a holistic view of mapping software apps to business competencies for critical problem-solving.

Organizations are faced with serious application sprawl and a growing backlog of out-of-date and often unsupported applications; there are too many applications that overlap functionality, too old applications, etc. Application architecture rationalization makes good sense and is informed by understanding the current portfolio via checking whether you have multiple applications doing the same thing in different areas of the business, or whether there are multiple applications providing the same products/services.

Here are some best practices and design patterns for the application architecture layer:

Layered Architecture: Organize the application into distinct layers (presentation, business, data access) to promote separation of concerns, maintainability, and testability.

Model-View-Controller (MVC) or Model-View-Presenter (MVP) Pattern: These patterns help separate the user interface, business logic, and data models, making the application more modular and easier to develop and maintain.

Service-Oriented Architecture (SOA) or Microservices: Consider adopting an SOA or microservices approach, where the application is composed of autonomous, loosely coupled services that communicate through well-defined interfaces. This promotes scalability, flexibility, and independent deployments.

Domain-Driven Design (DDD): Use DDD principles to align the application's architecture with the business domain, ensuring the design reflects the problem the application is trying to solve.

Event-Driven Architecture: Implement an event-driven approach, where components of the application communicate asynchronously through the publication and consumption of events. This can improve scalability and resilience.

Dependency Injection: Use a dependency injection framework to manage the creation and lifecycle of objects, promoting loose coupling and testability.

Application architecture provides a holistic view of mapping software apps to business competencies for critical problem-solving. These best practices and design patterns can help you create a well-structured, scalable, and maintainable application architecture that aligns with the business requirements and technical constraints of your solution.
