Linux操作系统由Linus Torvalds于1991年开发。 Linux操作系统以其开源支持和高度灵活性而著称。多年来，Linux OS因其低依赖性，高模块化和广泛分布而在各行业中非常流行。 Linux操作系统用于内核功能，其体系结构也包括两层，分别称为内核层和用户层。
Solaris操作系统由Sun Microsystems于1992年开发。 Solaris操作系统最初以开源软件的形式发布，但随后在Oracle收购Sun Microsystems并将其扩容为Oracle Solaris之后以许可的形式发布。 Oracle Solaris用于服务管理工具，因为它易于更新并提供最佳性能。
