Pulumi
An infrastructure-as-code tool where engineers describe cloud infrastructure in ordinary programming languages (TypeScript, Python, Go, C#) instead of a special configuration language. It works across AWS, Azure, GCP and Kubernetes, and is often chosen by teams who want developers, rather than a separate ops team, to own their infrastructure.

Can explain why their team picked it over Terraform and how they tested their infrastructure code.
Ask them
