Terraform - colonising Azure!
summary
Uses Terraform to build a live multi‑cloud setup: launches two DigitalOcean droplets in Amsterdam (30–40s provisioning), uploads SSH keys, provisions Apache via remote-exec provisioners, then creates Azure VMs in Ireland (about 4 minutes each), and wires AWS Route 53 weighted health‑checked DNS to split traffic 50/50. Shows taint/plan/apply/state workflow, uses a YubiKey via the SSH agent for private key protection, demonstrates failing DigitalOcean and automatic failover to Azure, and the end‑to‑end build succeeds.
