From the article: "Modules which can be easily be deployed independently - when the need arises." I read this to mean that they would always be deployed independently, but now I think I misread it. He actually meant that they should be really easy to split. In practice, I think people with this view underestimate the difficulty in splitting even seemingly unrelated services from a monolith. Its never completely trivial. Its better not to start that way if it is foreseeable as an undesirable end state.
