This mono-repository showcases enterprise-level Linux infrastructure engineering capabilities through three comprehensive projects demonstrating DevOps and Platform Engineering best practices.

Projects Overview

1. Enterprise Infrastructure Simulator

A container-based simulation of enterprise Linux infrastructure with Ansible automation for provisioning, patching, hardening, and decommissioning operations. Includes failure simulation and scaling scenarios.

Key Features:

Multi-node Linux simulation using Docker containers
Ansible playbooks for infrastructure lifecycle management
Automated scaling and failure injection scripts
Enterprise-grade inventory and scenario management

2. Migration Validation Framework

A Python CLI tool for validating system migrations by collecting, comparing, and reporting on system state changes. Generates comprehensive before/after snapshots and HTML reports.

Key Features:

Automated system data collection (mounts, services, disk usage)
JSON snapshot generation and comparison
HTML report generation with change visualization
CLI interface for enterprise migration workflows

3. Observability Stack

A complete monitoring and logging stack using ELK (Elasticsearch, Logstash, Kibana) and Grafana for comprehensive infrastructure observability.

Key Features:

Docker Compose deployment of full observability stack
Sample log ingestion and processing pipelines
Alerting rules and incident simulation scenarios
Real-time dashboards and monitoring capabilities

Architecture
