Pulumi itself (https://www.pulumi.com/) is a Modern Infrastructure as Code tool much like Terraform - but focused on modern cloud workloads like containers, serverless and Kubernetes - and using programming languages like Python, TypeScript, Go and .NET instead of constrained DSLs to bring improved software engineering capabilities into cloud infrastructure projects.

The Pulumi Kubernetes Operator (https://github.com/pulumi/pulumi-kubernetes-operator) is a new project that provides a Kubernetes-native way to continuously deliver cloud infrastructure defined using Pulumi into AWS, Azure, GCP or a Kubernetes cluster.
