Microsoft also promoted the release on Twitter, saying “Say hello to Microsoft Build of OpenJDK!”

Although traditionally a C# company, Microsoft has been shifting toward cloud computing, focusing on Azure services, and embraced open source by officially joining the OpenJDK community in 2019.

Microsoft noted that Java usage in its cloud services and development tools has been steadily increasing, prompting the creation of Microsoft Build of OpenJDK.

Microsoft Build of OpenJDK is a long‑term‑support, free, open‑source OpenJDK distribution that can be deployed anywhere.

The distribution includes OpenJDK 11.0.10 + 9 binaries for Java 11, supporting x64 servers as well as macOS, Linux, and Windows desktop environments.

Additionally, Microsoft has released early‑access binaries for Java 16 on Windows ARM based on the latest OpenJDK 16+36, built with the same scripts used by the Eclipse Adoptium project and tested against its quality‑assurance suite and the Java Technology Compatibility Kit (TCK) for Java 11.

Consequently, Microsoft Build of OpenJDK serves as a simple alternative to any other OpenJDK distribution in the Java ecosystem.

Azure users can experience it directly in a browser or via the Azure Cloud Shell in Windows Terminal.

Microsoft runs over 500,000 Java virtual machines internally, with more than 140,000 of them based on Microsoft Build of OpenJDK.

Microsoft plans to support Java 11 across Azure services through 2024, with Java 17 binaries slated for release at the end of the year, and the build will become the default Java 11 distribution for all Azure‑managed services.
