Packer vs Vagrant

Difference between Packer and Vagrant.

 Packer uses provisioners to set up a base image, while Vagrant uses provisioners to set up a dev environment on top of such an base image. For example, in a company, there are two different dev teams working on two different applications, and they are required to make their apps running in the same technology stack (let's say, Java7 + Tomcat7 + CentOS6). In this case, the company may ship a base image containing Java7+Tomcat7+CentOS6 using Packer, and the two dev teams can do some further customization using Vagrant provisioning capability for each dev environment.

Very simple and to the point
