My team owns an API monolith that hosts several completely unrelated endpoints. I keep thinking this would be a good candidate for breaking into microservices, but I do wonder if I'm buying into the hype.
That assuming they are big enough to warrant that in the first place.
IMO if it is a dozen unrelated endpoints but all of that still takes less than dev/month to manage it's probably entirely wasted effort to "fix it"
And if any of them grows to warrant dev/month or more.... separate that one and only that one out of that.
My biggest grief with microservices is the fact that it's effectively become a war on having a coherent logical normalized relational data model inside an organization.
I think it's actually quite rare for companies to have data so actually autonomous and unrelated that it does not logically relate to anything else in the organization.
