Arnoud Vermeer developed a Terraform-based example for provisioning PostgreSQL Database as a Service on Exoscale, contributing to the exoscale/terraform-provider-exoscale repository. He focused on automating and streamlining DBaaS deployments by leveraging Infrastructure as Code principles with Terraform and HCL, enabling reproducible and secure configuration management. The example included provider configuration, variable definitions, and settings for database name, plan, type, zone, admin credentials, and IP filtering, supporting self-service provisioning across environments. Arnoud also updated documentation to facilitate onboarding and adoption, demonstrating depth in cloud infrastructure and DBaaS while emphasizing reliability, security, and reduced manual intervention in deployment workflows.
