Pulumi lets you write code in languages you already know-such as TypeScript, Python, Go, C# or Java-to create and manage cloud infrastructure on platforms like AWS, Microsoft Azure, Google Cloud and Kubernetes. The platform provides IDE support, type checking, code reuse and an experience similar to application development.

One strength of Pulumi is that you avoid using a domain-specific infrastructure language and instead can use full-featured programming languages-making it easier to handle complex logic, test your code and integrate with CI/CD pipelines. Pulumi also offers an open-source project (Apache 2.0 license) and a cloud-hosted backend for state, secrets and team collaboration.

For those with basic technical experience who want to treat infrastructure as software, Pulumi is an attractive option: you’ll become familiar with concepts like stacks, code-based components and reusable infrastructure libraries-while retaining software engineering practices such as testing, refactoring and versioning. Be aware that the learning curve can be steeper than with some simpler DSL tools, especially if the team’s members are not used to writing code for cloud infrastructure.
