Pulumi is an open source (Apache 2.0) infrastructure-as-code platform that provisions cloud resources using general-purpose languages -- TypeScript, Python, Go, C#, Java -- or an optional YAML mode, across 170+ registry providers including AWS, Azure, Google Cloud, and Kubernetes. State can be stored in the free hosted Pulumi Cloud backend or in a self-managed backend such as S3, Azure Blob, GCS, or the local filesystem. Paid Pulumi Cloud tiers add SSO/RBAC, policy enforcement, audit logs, and automated drift detection for teams.
Platform and infrastructure engineers who want to define, deploy, and manage cloud infrastructure using general-purpose programming languages instead of a templating DSL, from individual developers up to enterprise platform teams needing SSO, RBAC, and compliance controls.
An Apache-2.0-licensed CLI and language SDKs for TypeScript, JavaScript, Python, Go, .NET, Java, and YAML; access to the Pulumi Registry of 170+ cloud provider packages; and, optionally, the hosted Pulumi Cloud service for state storage, secrets, policy packs, and team collaboration.
A Pulumi program declares desired resources in a supported language; `pulumi preview` computes and displays the diff against the recorded state without changing anything, `pulumi up` applies it, and `pulumi refresh --preview-only` detects drift between recorded and actual cloud state.
