Pulumi adds support for Java and YAML, aiming to provide universal coverage across programming languages and infrastructure types.
Infrastructure as code (IaC) vendor Pulumi is expanding its offerings by adding support for Java and YAML, aiming to give developers the flexibility to use their preferred programming languages to manage and provision infrastructure. This move reflects Pulumi’s commitment to providing universal coverage across different programming languages and infrastructure types.
Pulumi’s core open-source IaC SDK previously allowed developers to manage infrastructure using a variety of languages, including .NET, C#, F#, PowerShell, Node.js, JavaScript, Go, and Python. With the new update, support is extended to include all JVM languages—Java, Scala, Clojure, Groovy, and Kotlin. This extension addresses the increasing demand from enterprise users for Java support, as highlighted by Pulumi co-founder and CEO Joe Duffy. “With any language, we tend to wait until demand is deafening, and we reached that stage with Java over the last year,” Duffy explained. The inclusion of Java aligns with Pulumi’s strategy to cater to a diverse range of development environments and enterprise needs.
In addition to Java, Pulumi is also adding support for YAML, the widely used configuration language in Kubernetes environments. Duffy noted the limitations of YAML and described Pulumi’s approach as a way to simplify adoption while retaining flexibility. “You hit a limit with YAML very quickly,” he said. Pulumi’s solution allows developers to start with YAML for simpler tasks and then transition to more powerful languages like Python when necessary. This “eject” feature is designed to provide a smoother transition for developers as their infrastructure management needs become more complex.
The Pulumi Cloud Engineering Platform now supports reusable multi-language components, enhancing its functionality with secrets management, CI/CD integrations, policy as code, and access to the Pulumi Registry. Earlier this year, Pulumi also introduced a Business Critical edition tailored for enterprise customers with specific requirements, further solidifying its position in the enterprise market.
A key part of Pulumi’s strategy is the open-source CrossCode project, which serves as a translation layer between the chosen programming language and the deployed infrastructure code. “CrossCode is our secret sauce,” Duffy said. “It’s the open-source secret to how we can bring new languages to the platform.” This layer facilitates the integration of new languages into Pulumi’s ecosystem, providing a common framework for translating code across different languages.
Finally, Pulumi is enhancing its platform with 30 new reusable packages, including support for Oracle Cloud, Databricks, and EventStore. These additions aim to broaden Pulumi’s compatibility with various cloud services and data platforms, further supporting developers in creating versatile and scalable infrastructure solutions.
