The Reluctant Sysadmin's Guide to Securing a Linux Server
Overall, I think in an article that focuses on cloud computing (specifically AWS) there's too much time being spent in the local command line of a server.
It's an especially revealing sentence when the authors says that "Most attacks won’t be against what we’ve covered in this guide, but against the applications you install next. Properly done, containers can limit the impact."
If we are running containerized applications and we are already in the cloud, why are we futzing around on the command line of a Linux box? Why are we not using a cload orchestrator that abstracts the OS from the equation entirely?
If we do have a need to be on a bare Linux box, all of this OS configuration is better handled with cloud init [1], a configuration management tool like Ansible, and/or by building an image with Packer.
I know that seems like overkill for a small hobby reluctant sysadmin project type of deal but it's very little extra effort once you get used to the workflow. I would even recommend putting this infrastructure in Terraform even though, again, it seems like overkill at first.
Someone else in the comments mentioned that it's easier to just start with a hardened image from the AWS Marketplace, and I also agree with that idea. Find a free hardened image and make that the base for your system.

Which cloud services should I learn ?
You can just lift and shift an exisiting project into the cloud, but let's say you're using AWS's CFT's to define an EC2 instance. Great! throw in some cloud-init ( https://cloud-init.io/ ) script for your ubuntu cloud image for some automated-ness in provisioning and you're off to the races!
-
And so it begins....
You can run an os that has a cloudinit setup. This will on boot do whatever you have in the cloud init file. Check out https://cloud-init.io/ its becoming a standard in operating systems that aren't desktop oriented.

Here is another post about "which hypervisor to use ?"
Oh, and as a big bonus, Xen Orchestra supports cloud-init which is a really nice way to customize VMs from a baseline.

User_data does not apply on AWS ubuntu images
Since this is the standard Ubuntu image it's presumably cloud-init which is interpreting your user_data, in which case there are two other possible techniques to use to get this key registered.
-
userdata
Most Linux distribution images in EC2 include cloud-init which runs on startup and retrieves the user data. If you are using a standard Linux distribution AMI then it's probably cloud-init that is taking actions based on your user data, and so cloud-init's documentation on User Data Formats is the relevant reference for you.
