Vagrant is able to define and control multiple guest machines per Vagrantfile. This is known as a “multi-machine” environment.

These machines are generally able to work TOGETHER or are somehow associated with each other. Here are some use-cases people are using multi-machine environments for today:

Accurately modeling a multi-server production topology, such as separating a web and database server.

Modeling a DISTRIBUTED system and how they interact with each other.

Testing an interface, such as an API to a service component.

Disaster-case testing: machines dying, network partitions, slow networks, inconsistent world VIEWS, ETC.
