Phase 1: Linux Bash and Networking fundamentals
How does this phase apply to Cloud?
The cloud is a bunch of Linux Servers networked together. Learning the fundamentals of how networking works, and how to interact with these servers via commands, and automating those commands via a script, is what this phase is about. If you're already a Linux admin or network engineer, you can apply your skills to the cloud.
How to break down this phase
I would suggest spending time on these three topics and this timeline:
|1||Introduction to Bash Commands|
|2||Introduction to Bash Scripting|
|3||Introduction to Networking|
Of course feel free to spend as much time as you'd like, people have asked for a timeline and breakdown so I've added it.
|Bash||Linux Basics for Hackers||This book made learning Linux FUN! It's pretty easy to follow and take a chapter day by day.||You don't need to read the whole thing, the first 9 chapters cover most of what you need to know.|
|Bash for Beginners||YouTube Video Series||An introduction to Bash!||A 20 part YouTube series covering the fundamentals of Bash.|
|Networking||Fundamentals of computer networking||You'll learn the fundamental principles of computer networking to prepare you for the Azure admin and developer learning paths.||Read this after the previous video.|
Here are some projects to reinforce what you've learned in this phase. I recommend blogging or creating video content on your projects.
|Deploy a Linux VM using a CLI to any Cloud Platform||Ubuntu on public clouds|
|Setup a LAMP server||Configure the VM deployed previous to be a LAMP server|
|Convert video files||Checkout ffmpeg use it to write a script that converts a .mov file to mp4|
|Test your Bash skills with OverTheWire!||Bandit|

Certifications you might want to look into
There are several Linux certifications and you can chose to study for any of them, but a lot of them cover WAY more than what you need to know for a solid foundation and are more focused on Linux administration.
There are also TONS of networking certifications out there, and similar to the Linux ones, they are more focused on giving you a lot of knowledge so you can become a networking engineer/specialist, again at an introductory level, it's a little overkill. If you did want to get one, take a look at the Cisco certifications which are pretty much industry standard and/or Comptia Network+
At the end of the day, if you want to take them, go for it :)
