# Packer

Packer is a tool that allows us to create VM images. In here I will be mainly focusing on craeting AWS AMIs using Packer.

One problem we are facing it that we have to install various applications in out VM images after booting them. However, packer allows us to create custom VM images with preinstalled software. This can speed up the boot time of our VM instances.
