What is Pulumi?
Pulumi is an open-source infrastructure-as-code platform that lets engineers define cloud resources in general-purpose languages (Python, TypeScript, JavaScript, Go, C#/.NET, Java, or YAML) instead of a DSL like HCL. Pulumi was founded in 2017 and is based in Seattle, USA. The core SDK and CLI are open source (Apache 2.0); state and collaboration are handled by Pulumi Cloud or a self-managed backend.

PulumiInfrastructure as CodeInfrastructure as code using general-purpose programming languages
Key capabilities
- Multi-language SDKs: Define infrastructure in Python, TypeScript, Go, .NET, Java or YAML across 150+ providers.
- State & collaboration: Pulumi Cloud manages state, history and RBAC, or bring your own backend (S3, Azure Blob, self-managed).
- Policy as code: CrossGuard enforces compliance rules before infrastructure changes apply.
Where Pulumi fits
Infrastructure as code, cloud provisioning and policy-as-code across AWS, Azure, GCP and Kubernetes are the primary use cases.
Positioning and limitations
Shortlist Pulumi when your team wants to write infrastructure in the same language as your application code and reuse existing testing, linting and package-management tooling. Compare it against Terraform/OpenTofu if your team is already fluent in HCL, or against cloud-native IaC (CloudFormation, ARM/Bicep) if you're single-cloud.
A trial should provision a real stack end-to-end and confirm your team's preferred language, state backend, and CI/CD integration work together before standardizing on Pulumi.
