You’ve probably created a machine image at some point. A base image for AWS that builds upon someone’s work by adding a particular version of Java or Python or a new utility. Did you create the image on AWS using an EC2 instance, login, run some yum or apt-get and then save it? Great, and if someone wants the source code for that image or you want to build a similar image on a different region or provider? Well, Packer is an IaC tool for automating the construction of machine images.
