Canonical Netplan vs. Pulumi

Netplan is a utility for easily configuring networking on a linux system. You simply create a YAML description of the required network interfaces and what each should be configured to do. From this description Netplan will generate all the necessary configuration for your chosen renderer tool.

Pulumi lets you build, deploy, and manage cloud infrastructure in the programming languages you already use, on any cloud. Developers and platform engineers write infrastructure in TypeScript, Python, Go, C#, Java, or YAML, with the same loops, functions, classes, package managers, IDEs, and test frameworks they use everywhere else. No domain-specific language to learn. Application and platform teams work from one codebase and one workflow, whether they're shipping to public, private, hybrid, or multiple clouds.
