Microsoft customers that want to run an open source implementation of Java in its Azure cloud will have a new OpenJDK for Windows Server on Azure to choose from.
Microsoft's Open Technologies subsidiary and its partner Azul, maker of the Zing Java runtime for enterprise, plan to release a newly-built OpenJDK for Windows Server on Azure by the end of the year.
The OpenJDK for Windows on Azure will be freely distributed and licensed by Azul under the GNU GPLv2. Azul will also certify the OpenJDK will be compliant with the Java SE specification.
The companies announced the plans at the O'Reilly Open Source Convention on Wednesday.
"This partnership will enable developers and IT professionals to ensure their mission-critical apps deploy and run smoothly on Windows Azure, using the open source Java environment they prefer," MS Open Tech president Jean Paoli said in a statement.
The new open Java partnership follows the tie-up between Microsoft and Oracle to add greater support for a range of Oracle software running in Azure, including Oracle's Java. Microsoft is offering a fully licensed and supported Java offered in Windows Azure while Oracle is providing certification and support for Oracle applications, middleware, database, and Oracle Linux on Windows Server Hyper-V and Azure.
