Creating machine images


Creating or baking your own Amazon Machine Images (AMIs) is a key part of systems administration in AWS. Having a pre-baked image helps you provision your servers faster, easier, and more consistently than configuring it by hand.

Packer is the de facto standard tool that helps you make your own AMIs. By automating the launch, configuration, and clean-up of your instances, it makes sure you get a repeatable image every time.
