Which hypervisor is used with almost all collaboration applications?
- Sun xVM Server
- VirtualBox
- Xen
- VMware ESXi (vSphere)
Explanation: VMware ESXi (vSphere) is the hypervisor used with almost all collaboration applications. It is a software package consisting of a lightweight operating system and additional software designed to create and manage virtual environments.
Cisco Unified Communications applications began supporting virtualization with VMware ESXi 4.0, and most current versions of collaboration applications require at least ESXi version 5.0. While other hypervisors exist, the sources explicitly note that applications such as Microsoft Hyper-V, Citrix Zen (Xen), and Red Hat KVM are not currently supported for these specific collaboration workloads. The hypervisor acts as an abstraction layer between the physical hardware and the virtual machines, managing resources like CPU cores, memory, and networking to ensure that multiple independent operating systems can run simultaneously on a single physical server.
