Vagrant Concepts
Internal
Environment
An environment is identified by an ID. It has a name, a provider, and a directory, and at any moment is in a specific state (for example, "running"). The details of all environments for the logged in user is given by the vagrant global-status command.
The environment ID can be used to control the machine from anywhere on the system, by any command that takes a target machine.

State
Global State
Vagrant maintains state corresponding to all its resources managed for a specific user in ~/.vagrant.d
- relationship between an environment and global state.

Box
Vagrant boxes are prepackaged development environments that are the foundation of Vagrant. In most cases, this is usually just a stripped and naked operating system such as Ubuntu, Debian, or CentOS. Boxes exist with the intention to be provisioned with additional features like Apache and PHP using tools like Chef or Puppet. There are publicly available Vagrant boxes: https://www.vagrantup.com/docs/cli/box.html

Plugin
A plugin extends Vagrant by adding new functionality such as new providers. Plugins extend Vagrant using a stable API. Most of the core Vagrant functionality is implemented using core plugins. Plugins are usually packages as RubyGems.
Plugin Operations
Provider
A provider is the functionality that allows Vagrant to support a specific type of VM. Vagrant ships out of the box with support for VirtualBox, HyperV and Docker. Support for other types of machines can be added via external providers, integrated with Vagrant via plugins. Examples of such providers are AWS provider.
