Pulumi
In plain terms
An infrastructure-as-code tool using real programming languages.
Going deeper
Pulumi lets you define cloud infrastructure in languages like Python, TypeScript, and Go instead of a custom DSL. It brings general-purpose code to IaC.
Under the hood
Real languages enable loops, functions, and testing; multi-cloud like Terraform but code-first.
Examples
Multi-cloud provisioning, IaC in TypeScript/Python, automated infrastructure.
Think of it like...
Like writing your building plans in a full programming language instead of fill-in-the-blank forms.
