> First you need to learn Packer, or Terraform, or Salt, or Ansible - how do you pick one? You don't. These are complementary tools. Packer builds images. Salt, Ansible, Puppet or Chef _could_ be used as part of this process, but so can shell scripts (and given the immutability of images in modern workflows, they are the best option). Terraform can be used to deploy images as virtual machines, along with the supporting resources in the target deployment environment. |

I don't see the point of your post, and frankly sounds like nitpicking.
Ansible is a tool designed to execute scripts remotely through ssh on a collection of servers, and makes the job of writing those scripts trivially easy by a) offering a DSL to write those scripts as a workflow of idempotent operations, and b) offer a myriad of predefined tasks that you can simply add to your scripts and reuse.
Sure, you can write shell scripts to do the same thing. But that's a far lower level solution to a common problem, and one that is far hardsr and requires far more man*hours to implement and maintain.
With Ansible you only need to write a list of servers, ensure you can ssh into them, and write a high-level description of your workflow as idempotent tasks. It takes you literally a couple of minutes to pull this off. How much time would you take to do the same with your shell scripts?
