Hari Sekhon - Knowledge Base from 20 years in DevOps, Linux, Cloud, Big Data, Security, AWS, GCP etc
Work in progress to gradually migrate my huge private personal knowledge base into this public repo.
Star and watch for updates.
This repo focuses on advanced knowledge, tips & tricks, performance tuning, troubleshooting, debugging, workarounds & fixes.
Much more advanced knowledge is captured in code and code comments. References to my major GitHub Repos are provided throughout where relevant.
References to official docs and some classic books are provided for those who want to thoroughly cover the basics.
Most of these pages are far from fully ported and populated yet from my private knowledge base pages, some are stubs pending migration.
