What are the disadvantages of service layer architecture?

What are the disadvantages of service layer architecture?

Some disadvantages include increased complexity, potential performance overhead, and challenges in debugging.

Can you explain how increased complexity affects development?

Increased complexity can lead to longer development times, more difficult maintenance, and a steeper learning curve for new developers.

What about performance overhead? How significant is it?

Performance overhead can vary, but it often arises from additional network calls and data transformations, which can slow down response times.

Are there any specific scenarios where it's particularly problematic?

Yes, in high-performance applications or real-time systems, the added latency from service layers can be detrimental.

What alternatives do you suggest to mitigate these issues?

Alternatives include using microservices with direct communication or optimizing the service layer to reduce overhead.
