What is Vagrant used for?

Vagrant is used to create and manage virtual development environments, ensuring that developers always have the same setup. Developers specify their configuration in a Vagrantfile, which automates the process of starting the appropriate operating system and installing all necessary tools or libraries. This guarantees that everyone works within the same environment and helps prevent issues that only occur on a single person's machine. Vagrant is mainly used for setting up development and testing environments or automating deployment processes. It frequently integrates with VirtualBox, Docker, and VMware to facilitate virtualisation.
