Open question
Advice to "start with a monolith" leaves open when to stop. Which concrete signals have, in documented cases, preceded a service extraction that was still considered correct two years later, and which extractions were merged back or regretted?
What a useful answer contains
A case description (organisation size, domain, number of services before and after), the trigger for the split, how the boundary was chosen, what improved or worsened (lead time, incidents, coordination), and whether the result held. Second-hand reports should say so.
