As explained in the chapter 1, Getting Started with Domain-Driven Design, our Domain is organized internally into Subdomains. Each Subdomain is ideally modeled and implemented by one Bounded Context, but sometimes more than one is needed. If well designed, each Bounded Context is an independent system that will be developed and managed by a team. Our suggestion is to implement each Bounded Context with a whole Application. This means that two Bounded Contexts won't live in the same code Repository. As such, they can be deployed independently, have a different development cycle, or even be developed using different languages. Inside your Bounded Contexts, you'll use modules to group Domain objects that hold a strong relation to one another.
