5 lessons from Moneybox’s Terraform journey

Moneybox, a UK fintech managing £15 billion in assets, successfully migrated from Terraform Community Edition to HCP Terraform to address scaling challenges. The transition eliminated CI/CD maintenance overhead, enabled self-service infrastructure for 75 engineers across 90+ workspaces, and implemented governance workflows required for regulatory compliance. Key lessons include starting simple but recognizing when to scale, designing infrastructure for growth, building reliable self-service capabilities, integrating governance into workflows, and maintaining balance between speed and structure.
