SmartOS

SmartOS is an open-source operating system designed for running cloud and data center applications efficiently. It combines the stability of traditional UNIX systems with cloud-native features, relying on technologies like Solaris, zones (lightweight virtual machines), and Docker containers for flexible and secure resource management. SmartOS allows multiple isolated environments to run on a single physical server, optimizing hardware usage and simplifying maintenance. It is popular for hosting virtual servers and large-scale applications, providing a streamlined, scalable platform for modern computing needs.
