Powering Development and Testing Environments with Vagrant
Vagrant is a tool that allows developers to easily create and configure consistent development environments. It creates virtual machines that mirror production environments, allowing developers to work locally. Vagrant handles the installation of software, configuration, and provisioning so developers can focus on coding. It ensures environments are consistent across teams by managing environments through files under version control. Vagrant solves problems with traditional development environments by making them repeatable, isolated, and easy to understand.
