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
