Pulumi

Pulumi is an open-source infrastructure as code platform that enables engineers to define, deploy, and manage cloud resources using real programming languages rather than domain-specific languages. Instead of relying on custom DSLs or configuration files, users write infrastructure code in familiar languages such as Node.js (TypeScript/JavaScript), Python, Go, .NET (C#, F#, VB), Java, and even YAML for simpler cases. This approach allows teams to leverage existing IDEs, linters, testing frameworks, and package management workflows directly on their cloud infrastructure definitions. At its core, Pulumi treats infrastructure as code by converting high-level language constructs into API calls against cloud providers like AWS, Azure, Google Cloud, Kubernetes, and over 60 others through a rich ecosystem of providers. The platform supports both declarative and imperative styles, giving users the flexibility to create reusable components, functions, and abstractions that mirror software engineering practices. A key feature is the ability to use loops, conditionals, and error handling directly in infrastructure definitions, reducing the boilerplate common in HCL or YAML-based tools. Pulumi also introduces an agentic infrastructure layer named Neo, an AI-powered engineering agent that can interpret natural language requests to generate, modify, or troubleshoot infrastructure code. Neo integrates with the Pulumi engine to propose changes, preview deployments, and even execute operations under human supervision. This capability targets reducing the learning curve for teams new to cloud infrastructure and speeding up routine tasks for experienced engineers. Beyond code definition, Pulumi provides built-in state management with automatic locking, concurrency control, and remote stor
