Pulumi, a leading vendor in the infrastructure as code (IaC) space, has expanded its platform to support Java and YAML, providing developers with even more flexibility in managing and provisioning infrastructure. This move aligns with Pulumi’s commitment to enabling software developers to use their preferred programming languages rather than being confined to domain-specific languages or configuration formats. By integrating Java and improving YAML support, Pulumi continues to broaden its appeal among a diverse range of developers and enterprises.
Pulumi’s open-source infrastructure as code SDK has always stood out for its ability to work with mainstream programming languages such as Python, JavaScript, TypeScript, Go, and .NET. With the addition of Java, Pulumi now supports all JVM-based languages, including Scala, Kotlin, Clojure, and Groovy. This development allows enterprise developers who rely on Java and its ecosystem to seamlessly manage cloud infrastructure without having to learn new tools or languages like Bicep. By embracing widely-used programming languages, Pulumi eliminates barriers for developers transitioning to infrastructure as code practices.
Java support has been a highly requested feature, especially as Pulumi gains traction in enterprise environments. “With any language, we tend to wait until demand is deafening, and we reached that stage with Java over the last year,” said Joe Duffy, Pulumi cofounder and CEO. He noted that as Pulumi’s adoption grows among large organizations, Java—long a staple in enterprise software development—has become a frequent request from customers.
In addition to Java, Pulumi has made strides to address pain points associated with YAML, a configuration language often criticized for its limitations. While YAML is commonly used to manage Kubernetes environments, it can quickly become unwieldy for complex tasks. Pulumi’s approach simplifies YAML usage by allowing developers to write in languages like Go or Python and consume those configurations in YAML. When developers encounter YAML’s limitations, they can leverage Pulumi’s “convert” feature to transition to a fully supported programming language. This dual approach combines the simplicity of YAML for basic tasks with the power and flexibility of languages like Python or Java for more complex infrastructure management.
