If you are not hitting one of the -- 1) slow rate of deployed changes, 2) app performance is sluggish, or 3) freedom to choose language<->problem issues, 4) poor resource utilization across a fleet of boxes, then I don't see the rush to change anything. In that one of these issues would need to justify the investment to make the switch. Normally people are looking for a solution to one of these really broken/festering issues and they see microservices as a solution. For example, maybe your code deploys are super slow due to developer contention and a competitor is going to kill you -- maybe it's worth a look. Or, maybe you are blowing 100k / month on cloud servers, that if only you could get better utilization, you could save all that money. You get the idea. Here are some pretty good war stories told by people in the trenches. Highly suggest watching these talks by TellApart [1] & Wunderlist [2]. Both talk about the pain points of why they moved to microservices.
