What are the downsides of coupling in architecture?

What are the downsides of coupling in architecture?

Coupling in architecture refers to the degree of interdependence between software modules. High coupling can lead to several downsides, such as reduced modularity, making it harder to maintain and test individual components.

Can you explain how high coupling affects maintainability?

High coupling makes it difficult to change one module without affecting others. This can lead to increased time and effort in maintenance, as changes may require extensive testing across multiple components.

What are some examples of high coupling in real-world applications?

Examples include tightly integrated systems where a change in one service requires changes in others, like a monolithic application where all features are interdependent.

How can developers reduce coupling in their designs?

Developers can reduce coupling by using design principles like separation of concerns, dependency injection, and creating well-defined interfaces between modules.

Are there any situations where some coupling is beneficial?

Yes, some coupling can be beneficial for performance reasons, especially when modules need to communicate frequently. The key is to find a balance.
