Microsoft has built their own version of OpenJDK.
This build of Open JDK 11 is available on Azure as well as for users to download and install on their local machine.
According to Microsoft’s Dev Blogs:
They rely on Java technologies for a variety of their own internal systems, applications, and workloads to enable well-known public services and products as well as a significant set of mission-critical systems that power Azure infrastructure. They have been working on optimizing their Java-based systems and securing their supply chain to benefit their customers and users.
They have deployed over 500,000 Java Virtual Machines (JVMs) internally – excluding all Azure services and customer workloads – with needs that go from back-end microservices to Big Data systems, message brokers, event streaming services, and gaming servers. More than 140,000 of these JVMs are already based on the Microsoft Build of OpenJDK.
Microsoft uses a variety of open-source Java projects for critical tasks across Azure to support its global infrastructure, as well as for Big Data and log analytics systems. The back-end services of both LinkedIn and Yammer are almost entirely implemented on distributed cloud-native Java microservices. Minecraft Java Edition also remains ubiquitous with a significant ecosystem of mods and a community of enthusiastic modders, and they leverage Java to run the servers behind Minecraft Realms.
Later this year, the Microsoft Build of OpenJDK will become the default distribution for Java 11 across Azure-managed services. Customers won’t have to perform any maintenance tasks, as the transition will be smooth and transparent through application deployments. For all other Azure services, customers can bring their JDK of choice, including Microsoft Build of OpenJDK. They will provide more updates on that in the coming months.
