Hypervisors and Virtual Machine Managers.

What is the difference between a hypervisor and a Virtual Machine Manager?

The difference could be nothing and everything. Some people use the term “hypervisor” very broadly to refer to any of the software that is used to manage virtual machines. Others differentiate between the two terms in this way: a hypervisor does not need a host operating system, while a Virtual Machine Manager (VMM) requires a host operating system such as Windows, OS X, or Linux.


Components of virtualization.Virtualization technologies.

Components of virtualization.

– Virtual desktops.» A virtual machine (VM) that functions as a desktop.

• Any modern operating system can be run inside of the VM desktop.

• Multiple virtual desktops may be hosted on, or from, a single host system.

– Virtual servers.» A virtual machine (or machines) that functions as a

server.• Any modern server operating system can be used.• Multiple virtual servers may be hosted on, or from, a

single host system.

– Virtual switches, firewalls, and routers.

» A virtual machine (or machines) that fulfills the functions of a switch, firewall or router.

• Virtual firewalls and routers are particularly effective when combined with virtual network interface controllers (NICs) and virtual switches to create virtual networks.



An important consideration when designing a virtual network is how the virtual network is going to pass traffic to remote networks.

Virtualization, by its nature, leads to either an open and highly scalable network or a closed self-contained system. It is possible to create a completely self-contained network with all of the virtual components and never have the network traffic leave the host machine.

If there is a desire or need for network traffic to pass beyond the host system, then that function needs to be specifically granted. A connection must be created between the host system’s physical NIC and the virtual networking equipment to allow network traffic to pass through.


Software defined networking.Virtualization technologies.

Software defined networking.

Software defined networking (SDN) is the process of allowing the administration and configuration of a network to be done dynamically.

With SDN, the administrator uses a front end program to make adjustments to the network. The program sends the instructions to the networking equipment, which is then reconfigured to perform as desired.

SDN can allow network administrators to dynamically adjust network performance without the need to log into each individual device that needs to be adjusted to achieve the desired performance.

SDN is considered to still be an emerging technology.


What was covered.Virtualization technologies.

Depending on the source, a hypervisor and a VMM may be considered to be the same thing. Others differentiate the two this way: a hypervisor doesn’t require a host operating system in order to function and serve up VMs, while a VMM requires the use of an underlying host operating system in order to function.

Summary

Virtual machines can be created to fulfill almost any function in the modern network (e.g., virtual desktops, servers, routers, and switches). Virtual networks may be completely self contained, or a connection may be created between the host system’s physical NIC and a virtual networking device to allow network traffic to pass through system.


SDN is an emerging technology that is being used to allow network administrators to dynamically adjust network performance from a single interface. This eliminates the need for the administrator to log into each network device that needs to be adjusted in order to achieve the desired performance.
