## Overview

This repository is a collection of hands-on DevOps/cloud learning projects, rather than one application. The principal user workflow is to choose a project and follow its practical implementation and validation guidance; the README describes projects spanning cloud infrastructure, application deployment, automation, and monitoring. The tree also contains runnable application examples, including quiz, blog, catalog, and storefront software. The graph groups these representative runtime systems; many project internals and the broader project guides were not sampled, so their detailed interactions are omitted.
