What was the reason for abandoning the chosen architectural model?

Refusal of the chosen architectural model usually occurs due to several reasons:

• Low scalability: the architecture cannot cope with the growth of load or functionality.
• Support complexity: the code becomes difficult to maintain and develop due to a tangled structure.
• Performance issues: the architecture leads to redundant calls, delays, or excessive resource consumption.
• Lack of flexibility: it is difficult to implement new requirements or integrate with other systems.
• Technical debt: accumulation of outdated solutions that hinder development.

For example, abandoning monolithic architecture in favor of microservices is often associated with the need to improve scalability and component independence.
