The Investment Case
Implementation cost: 2-3 engineers for 3-6 months ($200-500K). Returns: 80% reduction in provisioning time, 90% fewer configuration errors, 60% faster disaster recovery, 50% reduction in audit preparation time.
Compliance bonus: SOC 2 and ISO 27001 audits are 3-4x faster with IaC because you have a documented, version-controlled audit trail.
