Challenges

SCS describes an architectural approach that is more narrowly defined than microservices. Therefore, SCS cannot be the approach for solving all problems.

Limitation to web applications

The first limitation of SCSs is that they are web applications. Thus, SCSs are not a solution when a web UI is not required.

However, some aspects of SCSs can still be implemented in a scenario that does not involve web applications: the clear separation of domains and the focus on asynchronous communication.

If a system is to be developed that offers only an API, an architecture can be created that provides at least some of the advantages of SCSs.
