Case Study: Eventbrite achieves automated multi-account AWS governance with HashiCorp Terraform Landing Zone

Terraform Landing Zones for Multi-Account AWS at Eventbrite

Eventbrite, the event technology platform, needed a better way to support its move from a tightly coupled single-AWS-account setup to a multi-account architecture with clear ownership, stronger isolation, and consistent security controls. Working with HashiCorp, the team looked for an infrastructure-as-code approach that could support self-service account creation, governance, and integration with Okta and their broader engineering workflows.

HashiCorp’s AWS Terraform Landing Zone helped Eventbrite build an automated “account vending machine” using Terraform Enterprise, with pull-request-based account requests, standardized baselines, shared networking and security guardrails, and policy-as-code enforcement. The result was a streamlined, repeatable way to provision new AWS accounts and supporting resources for teams, reducing manual toil and enabling Eventbrite to roll out its domain-based multi-account strategy; the talk notes the effort took about two engineers working almost full-time for three months to adapt the accelerator to Eventbrite’s needs.
