Operational Scenarios Catalog

This section hosts the practical execution layer of the portfolio. Each entry is structured as a Standard Operating Procedure (SOP), simulating real-world infrastructure tickets requiring configuration, troubleshooting, and validation in a live environment.

The objective is to demonstrate resolution capabilities under technical constraints aligned with industry standards (LFCS/RHCSA).

🏗️ Environment Topology (Standard Operating Environment)

All scenarios run on a standardized 7-node cluster. This topology simulates a three-tier architecture (Web, App, Data) with nested virtualization capabilities.

Node Inventory

Role	Hostname	Function / Business Context
Management	`terminal`	Operations Controller (Bastion Host) and main CLI.
Web Tier	`web-srv1`	SSL Termination, Reverse Proxy, and HTTP Server.
App Tier	`app-srv1`	Business logic execution and internal APIs.
Data Tier	`data-001/002`	Persistence, databases, and raw block storage.
Virtualization	`kvm-001`	Libvirt hypervisor for server consolidation.
Containers	`docker-001`	Runtime for microservices and lightweight orchestration.
