# === Types of Automation Services ===
# 1. Infrastructure Automation (IaC)
# Tools: Terraform, Ansible, Pulumi, CloudFormation
# Use cases:
# - Provision servers, databases, networks
# - Configure OS, packages, services
# - Manage cloud resources (AWS, GCP, Azure)
# Terraform Example: Create EC2 instance
