Case Study: Instacart achieves consistent management of 50+ AWS RDS PostgreSQL instances with HashiCorp Terraform

How Instacart Uses Terraform For Its AWS-Managed Postgresql Databases

Instacart used HashiCorp’s Terraform on AWS to manage a rapidly growing database environment, including more than 50 AWS RDS PostgreSQL instances and PGBouncers. As the company expanded, its infrastructure team faced the challenge of keeping dozens of hand-crafted database resources consistent and well-documented while maintaining standards across the stack.

With HashiCorp Terraform, Instacart automated the creation, update, and deletion of RDS Postgres instances, parameter groups, and EC2 instances running PGBouncers through reusable modules. Over two years, the team refined their Terraform-based management approach and achieved greater consistency and control across their database infrastructure, successfully standardizing the management of 50+ RDS instances.
