Xen is an open source virtualization technology that is designed to provide virtualization of operating systems and applications on servers and desktops. It is a hypervisor-based platform that runs multiple operating systems on a single physical machine and allows users to manage and deploy virtual machines, or VMs, on their own. Xen is designed to provide a secure and robust environment for running multiple operating systems in a single server or desktop, allowing users to easily manage and provision their own VMs and applications. It can be used to create a virtual private server (VPS) or a cloud computing environment. Xen also provides numerous security features to ensure that the VMs are safe from malicious attacks. Additionally, Xen provides a unified platform for managing multiple VMs and applications, eliminating the need for multiple systems to be running in a data center.
