Virtualization Flashcards
Virtualization
Self-contained computers running within a host OS
Virtual Machines
Virtualization
Support multiple VMs
Hypervisors
Virtualization
Hypervisor that runs directly on top of the hardware of an OS
Type 1
Virtualization
Hypervisor that runs as an app in an OS
Type 2
Virtualization
A commonly used hypervisor
VirtualBox
Virtualization
Download and install an OS
in Virtual Machine like ubuntu linux
Virtualization
Modifications to virtual hardware are
Easy
Such as adding a drive
Virtualization
You can connect a VM to the same network and DHCP server as host OS by
Bridging
Virtualization
To put a VM in a unique network ID
Use a NAT
Virtualization
Use a Nat network to put multiple VMs into a single
Network ID
Virtualization
Moves VMs “out there” but they are accessible by IP
Cloud Computing
Virtualization
Cloud computing benefit
rapid elasticity
Virtualization
Cloud computing benefit
On-demand scaling
Virtualization
Cloud computing benefit
Resource pooling
Virtualization
Moves network tasks such as firewalls into the cloud
IaaS
Infrastructure As A Service
Virtualization
Moves machines into the cloud so you can concentrate on apps
PaaS
Platform As A Service
Virtualization
Moves apps to the Cloud such as Google Docs
SaaS
Software As A Service
Virtualization
Cloud owned and used only by a single organization
Private cloud
Virtualization
Clouds that are privately owned but are available for public use
Public cloud
Virtualization
Clouds that have both private and public aspects.
Hybrid cloud
Virtualization
Clouds owned by multiple organizations for their own private use
Community cloud
Virtualization
Enables access to synchronized, saved, files from any device.
Cloud storage
Virtualization
Move management to the Cloud or e-mail and more
Cloud-based applications
Virtualization
Provide a consistent workspace in the Cloud accessible from any device
PVirtual desktops
Virtualization
Provides access to apps without installing them locally.
Virtual application
Virtualization - Quiz
A guest operating system that runs with a host operating system.
Virtual Machine
Virtualization - Quiz
Manages the guest OS and the interface between the guest OS and the shared physical hardware of the host OS.
Hypervisor
Virtualization - Quiz
The hypervisor can create a virtual optical drive from the
guest OS .iso file
Virtualization - Quiz
VM installation trifecta
Hypervisor -- Guest OS .iso file -- Virtual disk
Virtualization - Quiz
Many VMs support 3D technology but with host OS and other VMs
3D performance and resource sharing are limited.
Virtualization - Quiz
Great way to practice administering different OSs, to configure and experiment with virtual networking and experiment with multiple drives - instead of purchasing physical hardware
VMs and virtual disks
Virtualization - Quiz
Cloud services are NOT
hosted locally - they are somewhere in the cloud.
Virtualization - Quiz
Benefit of cloud-based apps is that they are installed on a cloud server
Not locally
