OpenIndiana

OpenIndiana is an open-source operating system based on the Solaris (originally Sun Microsystems) platform. It provides a robust, enterprise-grade environment suitable for servers and advanced computing tasks, emphasizing stability, security, and scalability. Built on the Illumos kernel, it supports modern hardware and features like ZFS storage, making it reliable for data management. OpenIndiana is often used by developers and IT professionals to run applications, manage networks, or serve as a free alternative to commercial Unix systems, enabling users to deploy a powerful, Unix-like system without licensing costs.
