Correct Answer : Hypervisor is a small software layer that enables multiple operating systems to run alongside each other. Hypervisor separates the VMs logically, assigning each its own slice of underlying computing power, memory, and storage. There are 2 types of Hypervisor : Type 1 & Type 2. Hosted is another name given to a Type 2 hypervisor. Type 2 Hypervisors : Run as an application in a host operating system, rather than in place of an operating system ⦿ Create a virtual machine and install a guest operating system on it ⦿ Assign physical resources to a virtual machine and set the amount of processor cores and memory it can use ⦿ Known as “hosted” ⦿ Mostly used for end-user virtualization, less frequently used, higher latency ⦿ Some examples are Oracle VirtualBox and VMware Workstation In-Correct Answers : Virtual Machine : A virtual machine is a virtual representation of physical computer, that behaves like an actual computer. Single Tenant : Sigle tenant means, used by single organization only. Bare metal server are single-tenant physical servers that are dedicated to a single customer. Bare metal servers fulfill the demanding needs of high-performance computing (HPC) and data intense applications. Use cases : Bare metal server are suitable for CPU and I/O intensive workloads.
