This repository started out as a learning in public project for myself and has now become a structured learning map for many in the community. We have 3 years under our belt covering all things DevOps, including Principles, Processes, Tooling and Use Cases surrounding this vast topic.

90DaysOfDevOps
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.
- DevOps - Written content by myself but then translated and corrected and enhanced by the community
- DevSecOps - Focus on Security and other topics we did not get to in 2022, Perspectives from communinty subject matter experts.
- Community Edition - Community Sessions by the community, 91 Sessions shared on YouTube. Different Media with intent to build out resources here as well.
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.
DevOps - This is where we start, 90Days, 110k words!
DevSecOps - Continues... Some help from my friends
