In virtualization deployment, we could run multiple VMs on a single server with their own OS.
Virtualization improved server utilization and minimized hardware expenses. Before knowing more about virtualization, we should know about hypervisors.
Hypervisor: A hypervisor, also known as a virtual machine monitor or virtualizer, is a type of computer software, firmware, or hardware that creates and runs virtual machines.
There are two types of hypervisors available:
**Type 1 Hypervisor
**Type 2 Hypervisor
\>> Type 1 Hypervisor \>>
Type 1 hypervisor are run directly on the system server.
** Popular type 1 hypervisors are:
--VMWare ESXI (part of the Vsphere suite)
--Microsoft Hyper-V
--Red Hat KVM
--Oracle VM Server
\>> Type 1 hypervisor virtualization model >>
--Hardware section (CPU, RAM, NIC-network interface card)
--Hypervisor (VMware ESXI)
--VM (virtual machine for different type of server)**
\>> Type 2 Hypervisor >>
Type 2 hypervisors run on top of the host operating system.
Popular type 2 hypervisors are****
--VMWork station (for windows and linux systems)
--Fusion (for MAC OS)
--Virtual Box (windows, linux and Mac-only Intel-based Macs)
\>> Type 2 hypervisor virtualization model >>
--Hardware section (CPU, RAM, NIC-network interface card)
--Desktop Operating system
--Hypervisor (based on local machine’s OS)
--VM (virtual machine for different type of server)
