Pulumi has introduced Pulumi YAML, a simple, YAML-based interface for its Infrastructure as Code (IaC) platform, expanding the flexibility of cloud infrastructure deployment. While Pulumi traditionally allowed developers to use languages like TypeScript, Python, and Java, Pulumi YAML is designed for smaller-scale use cases where a full-fledged programming language may not be necessary. It provides a straightforward way to define cloud infrastructure, utilizing YAML's widespread recognition in cloud environments like Kubernetes and Docker. Pulumi YAML can interoperate with existing Pulumi languages and access all core features such as native providers, secrets management, and more. It supports the creation of complex infrastructure setups while offering a path to convert to other Pulumi-supported languages if greater complexity is needed. Pulumi's platform capabilities, including policy as code and integration with the Pulumi Service, are fully available to Pulumi YAML users. Additionally, the open-source nature of Pulumi YAML allows for integration with other languages that compile to YAML/JSON, enabling diverse applications and seamless scaling of infrastructure projects.
