A company is considering consolidating a number of physical machines into a virtual infrastructure that will be located at its main office. The company has the following requirements:
High-performance VMs
More secure
Has system independence
Which of the following is the BEST platform for the company to use?
Correct Answer: A
A type 1 hypervisor is what would best meet the requirements of high-performance VMs (Virtual Machines), more secure, and has system independence for a company that wants to move its environment from on premises to the cloud without vendor lock-in. A hypervisor is a software or hardware that allows multiple VMs to run on a single physical host or server. A hypervisor can be classified into two types:
* Type 1 hypervisor: This is a hypervisor that runs directly on the hardware or bare metal of the host or server, without any underlying OS (Operating System). A type 1 hypervisor can provide benefits such as:
* High-performance: A type 1 hypervisor can provide high-performance by eliminating any overhead or interference from an OS, and allowing direct access and control of the hardware resources by the VMs.
* More secure: A type 1 hypervisor can provide more security by reducing the attack surface or exposure of the host or server, and isolating and protecting the VMs from each other and from the hardware.
* System independence: A type 1 hypervisor can provide system independence by allowing
* different types of OSs to run on the VMs, regardless of the hardware or vendor of the host or server.
* Type 2 hypervisor: This is a hypervisor that runs on top of an OS of the host or server, as a software application or program. A type 2 hypervisor can provide benefits such as:
* Ease of installation and use: A type 2 hypervisor can be easily installed and used as a software application or program on an existing OS, without requiring any changes or modifications to the hardware or configuration of the host or server.
* Compatibility and portability: A type 2 hypervisor can be compatible and portable with different types of hardware or devices that support the OS of the host or server, such as laptops, desktops, smartphones, etc.
