What is the difference between Vagrant and Terraform?

The difference between Vagrant and Terraform is in their purpose and scope. Vagrant can be used for creating consistent, virtualized development environments locally. Vagrant is normally used in combination with providers like VirtualBox or Docker to help keep environments consistent for all team members. This technology is best suited for local machine-based development and testing.
Terraform is an infrastructure-as-code tool used for provisioning and maintaining cloud resources at scale with providers like AWS, Azure, and Google Cloud. The said technology is used to define and automate cloud infrastructure in production environments, handling resources such as servers and networks. In other words, Vagrant works on local development while Terraform deals with managing cloud infrastructure.
