Enterprise Infrastructure Portfolio

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
