A personal reference library of technical notes, study guides, and documentation covering IT, Cloud, and DevOps topics — organized by subject and built up over 20+ years in the industry.
This repo started as the content backbone for cloud-master.io and continues to grow as a reference I return to and build on. If it's useful to you too, great.
Post-secondary education in IT is expensive and often outdated before you finish it. Industry certifications are a better path — focused, affordable, and recognized by employers. This library exists to support that path with supplemental notes and pointers to the resources that actually helped me.
Where official documentation or whitepapers cover something better than I can, I say so and link there instead.

I have 20+ years in the computer industry with certifications in Microsoft Windows, Linux, and AWS Cloud. This library reflects the topics I've worked through, studied for, and built on throughout that time.
It's not meant to replace the excellent resources already out there — it's meant to complement them and help you find them faster.
