How often in your team you had a conversation about this or that technology to adopt? How often the conversation became a massive argument that led to a sort of religious war?

If I would have to summarise in a single attribute what microservice adoption can give you, I would probably say, that the most important benefit of microservices is agility. Agility today is the number one priority for business who want to stay ahead of their competitors. That's why businesses are investing on microservices, not just to have happy hipsters around ;-).
