Adoptium

TLDR: Adoptium is a group that makes high-quality software for Java.

Adoptium is a group of companies and organizations that work together to create high-quality software for the Java programming language. They want to make sure that the software they create is free and open-source, which means that anyone can use it and modify it. The main goal of Adoptium is to provide high-quality runtimes and other technology that can be used with Java. They do this by building and providing OpenJDK based binaries, which are like pre-compiled versions of the software that can be easily installed and used. Adoptium also creates an open test suite for these binaries to make sure they work correctly. The group was launched in March 2021 by several companies including Alibaba Cloud, Huawei, IBM, Microsoft, and Red Hat.

One of the main projects of Adoptium is called Eclipse Temurin. This project produces a certified binary build of OpenJDK called Temurin. This build is compatible with Java 8, 11, and 17. The name Temurin is actually an anagram of the word "runtime," which is a term used to describe the environment in which software runs. Since 2023, members of the Adoptium Working Group, such as IBM, Open Elements, and Red Hat, offer commercial support for Temurin.

Adoptium originally started as a project called AdoptOpenJDK in 2017. It provided free and open-source Java runtimes for enterprises. In 2020, it moved to the Eclipse Foundation and became known as Eclipse Adoptium. The group continues to work on creating high-quality software for the Java ecosystem.

As of July 2023, there are 12 members of the Adoptium Working Group, including Alibaba Cloud, Google, IBM, Microsoft, and Red Hat.

In summary, Adoptium is a group that works together to create high-quality software for the Java programming language. They provide free and open-source runtimes and other technology that can be used with Java. Their main project is called Eclipse Temurin, which produces a certified binary build of OpenJDK. The group was launched in 2021 and has several members from different companies and organizations.
