Free to Use: the Microsoft Build of OpenJDK is at no cost to use.

Multi-Environment Support: cloud, local data centers, and user development environments.Multi-OS Support: Windows, macOS, and Linux.Become a leader in providing toolkits for the open-source community: Microsoft has been a sponsor and contributor to the Java open-source community through AdoptOpenJDK projects since 2018, and has contributed to OpenJDK by providing more than 50 patches for OpenJDK in the last 18 months, which includes resolutions for issues in macOS packaging, build, infrastructure, and garbage collection.Support Java devs: Part of Microsoft’s dedication to better support Java developers on Azure.Security & performance improvement: The build may contain backported fixes and enhancements for security and performance, which may not have formally backported upstream.It helps to reduce the overall Azure subscription costs by removing the cost passed to other vendors for JDK licenses. Cost reduction: Java support costs on Azure cloud can be reduced by avoiding commercial licenses for Java.LinkedIn, Minecraft, and Yammer are examples of major internal platforms run on Java.īelow are few critical triggers outside the rise of internal JVM workloads for Microsoft to jump into OpenJDK distribution: Azure has experienced significant growth in Java workloads through Azure Spring Cloud, Azure App Service, Azure Functions, and Azure Kubernetes Service. Microsoft runs more than 500,000 JVMs internally, excluding all Azure services and customer workloads. Microsoft has been deeply involved in the Java ecosystem by offering Java tools for Visual Studio Code, supporting Java on Azure, running several internal platforms, and some Azure infrastructure services on Java Virtual Machine (JVM).

Why Microsoft is Offering JDK Distribution? Microsoft is currently collecting feedback on the packing and installer of the build on various platforms from the users of the preview build and aims to release the GA build by the end of 2021. An early-access release for Java 16 is available for Windows on ARM. The preview build includes the binaries for Java 11 available on 圆4 server and desktop environments on Windows, macOS, and Linux. It’s a no-cost, Long-Term Support (LTS) distribution of OpenJDK currently available for preview.

Microsoft affirms its commitment to the Java ecosystem by offering open-source distribution of Java with the Microsoft Build of OpenJDK™.
