This repository started as a way to document my journey on getting a better foundational knowledge of "DevOps". It was started on the 1st January 2022 and ran to the 31st March 2022 which is 90 Days!

What started off as a learning in public project has quickly become a structured way of learning the foundations of DevOps principles, processes and tooling. Maybe you can help contribute some resources you have found useful to the project.

This will not cover all things "DevOps" but it will cover some of the areas that will benefit your learning and understanding overall in this space. The encouragement here is to read & watch the content, be curious, provide feedback and discuss within the community your findings.

The project is not a sponsored operation by any vendors and everything is accessible using free, community and open source software.

What is this?A structured learning curriculum for DevOps that grew out of a personal 90-day public learning challenge, now covering principles, processes, tooling, and real-world use cases like Kubernetes, Terraform, and Ansible.
Is this a course, a book, or just an index of links?It is written content organized day-by-day (90 days) plus a DevSecOps extension and a Community Edition with 91 YouTube sessions from community contributors.
Where should a beginner start?Start with the main DevOps section, which is the original 90-day written curriculum covering foundational principles, processes, and tooling, then move on to DevSecOps and the Community Edition videos.
Do I need any accounts or paid tools to follow along?No, everything referenced in the content is free, community, or open source software, with no vendor sponsorship involved.
Does this cover absolutely everything about DevOps?No, the author is upfront that it only covers select areas useful for learning, not the entire DevOps field.
Can I use this content commercially?No, the content is licensed under Creative Commons Attribution-NonCommercial-ShareAlike 4.0, which restricts commercial use.

Is the Community Edition still growing?Yes, it already includes 91 community-contributed YouTube sessions and the project explicitly invites others to contribute resources they find useful.
Why did the author start this project?Michael Cade started it on 1 January 2022 as a personal public-learning challenge to build foundational DevOps knowledge over 90 days, and it evolved into a community resource.
