We are such a totalitarian part of the species. Someone writes about microservices and my next project I'm building services for each feature because some manager heard it increases reliability. The fact is its always science. If you don't want your inconsistent dataset from somewhere else in the corporation taking down your application then chunk a part of the application into your own container to manage calls rather than allowing the event loop to block up. It doesn't have to be 'micro', it has to exist for some reason, if not it is just your developers trying to be cool.
