Master Pulumi with our step-by-step tutorial, detailed feature walkthrough, and expert tips.
Explore the key features that make Pulumi powerful for deployment & hosting workflows.
Pulumi lets you write infrastructure code in general-purpose languages like TypeScript, Python, Go, C#, and Java, while Terraform uses HCL, a domain-specific declarative language. This means Pulumi users get loops, classes, inheritance, package managers (npm, PyPI, NuGet), unit testing, and full IDE support — features customers cite as reducing deployment time from a week to under a day. Pulumi also supports 170+ providers and ships with a first-party AI agent (Neo) and integrated secrets management (ESC), whereas Terraform typically requires combining multiple separate tools. The trade-off is that Pulumi's flexibility requires programming experience, while Terraform's HCL is simpler for pure ops teams.
Pulumi Neo is the company's AI-powered infrastructure engineering agent — described as the first AI agent purpose-built for infrastructure. Neo reads your existing Pulumi code and organizational context, respects your governance policies, and can execute complex provisioning, refactoring, and debugging tasks end-to-end. It can operate with a human in the loop for approval or autonomously for routine changes. This makes it different from generic coding copilots because it understands your specific cloud architecture, secrets configuration, and compliance constraints rather than generating generic snippets.
Pulumi's open-source IaC engine is free and the Pulumi Cloud service offers a free Individual tier with unlimited resources for individual developers and small projects. Paid Team and Enterprise tiers add features like SSO, RBAC, advanced policy as code, Pulumi ESC, Insights, and Pulumi Neo, with pricing based on resource counts and team size. Self-hosting the state backend is also supported for organizations that want to avoid Pulumi Cloud entirely. Specific pricing tiers and resource limits are listed on the Pulumi pricing page.
Pulumi supports 170+ cloud providers and packages through its Registry, including the major hyperscalers (AWS, Azure, Google Cloud), Kubernetes, and dozens of SaaS providers like Snowflake, Datadog, Auth0, Cloudflare, and GitHub. The same Pulumi program can manage resources across multiple clouds and SaaS tools simultaneously, which is one reason customers cite it for multi-cloud and multi-region Kubernetes deployments. Providers are typically generated from upstream APIs, so coverage tends to track the underlying provider's surface area closely.
Yes. Pulumi Cloud is SOC 2 Type II certified, encrypts secrets at rest and in transit, and supports dynamic short-lived credentials via OIDC integrations with AWS, Azure, and GCP. Pulumi ESC centralizes secrets management across Vault, AWS Secrets Manager, Azure Key Vault, and other providers, and the platform provides full audit trails, RBAC, SSO, and policy as code for compliance. Enterprise customers like Mercedes-Benz, Snowflake, and Lemonade use Pulumi in production for regulated workloads, and Pulumi offers professional services for complex implementations.
Now that you know how to use Pulumi, it's time to put this knowledge into practice.
