What is Vagrant?

Vagrant is an open-source software product for building and maintaining portable virtual software development environments. It simplifies the process of configuring a virtual machine (VM) so that developers can focus on writing code instead of setting up their development environment. Vagrant uses a declarative configuration file to describe all the software and packages required to run an application, allowing teams to easily share and replicate environments across different operating systems and platforms. It's commonly used to create consistent development environments, test environments, and even for deploying applications in a controlled manner.
