Adoptium
Adoptium is an open-source community and platform that provides high-quality, enterprise-ready builds of the Eclipse Temurin Java Development Kit (JDK) and Java Runtime Environment (JRE). It ensures free, secure, and long-term support for Java distributions, offering binaries for multiple operating systems and architectures. The project is governed by the Eclipse Foundation and focuses on transparency, stability, and compatibility with Java SE standards.
Developers should use Adoptium when they need reliable, free Java distributions for production environments, especially after Oracle changed its licensing model for Java SE. It is ideal for enterprises seeking long-term support (LTS) versions with security updates, such as for server-side applications, microservices, or cloud deployments. Adoptium is also valuable for ensuring compliance with open-source policies and avoiding vendor lock-in in Java-based projects.
