Download and install both Vagrant and VirtualBox.

Simplicity: For monoliths, Vagrant is great since you'll have a deal with a much smaller subset of commands and problems than you do with docker. It's as simple as downloading vagrant and virtualbox and running vagrant up and vagrant ssh.
Lightweight: Docker containers however are much smaller than vagrant boxes, and mimic the exact build used for production since they are shared and reusable post-build.
Composability: However, Docker is more complex to use and requires having around 5+ verbose commands just to start using it. While it can be difficult to coordinate multiple Docker containers on a development machine, it's the best viable solution for coordinating micro-services and service-oriented architectures.
