It's way more than "just a configuration". > A function call or a remote call won't change the domain logic Understanding performance and minimizing failure modes and their impact on larger systems makes for a whole career as "SRE". Making remote calls all over a codebase creates behaviors that are practically impossible to debug or optimize. But the blocker is the network impact of large applications and the emergence of cascading failures.
