8. Virtualization Flashcards
What virtualization solution runs applications on servers in a centralized location?
Server-based (Terminal services)
What virtualization solution allows an application to be packaged up and streamed directly to a user’s PC?
Client-based (Application streaming)
What type of virtualization is applied by aa host OS to provision an isolated execution environment for an application?
Containerization
What happens in containerization when a physical server crashes?
All the organizations hosted on that same server are affected
What three things should containerized virtual servers in the cloud be properly set up with, especially when multiple organizations share a server?
Failover, redundancy, and elasticity
What three things should be secured to reduce risk of exploitation of hosting all VMs on the same type of hypervisor?
Proper configurations, patched and up-to-date hypervisor, tight access control
Which tool has the purpose of managing the distribution of a server’s physical resources to the VMs?
Hypervisor
Why does container-based virtualization have less resources?
It doesn’t require each individual container to have its own copy of the OS
What virtualization infrastructure allows for the full integration of storage, network, and servers without hardware changes?
Hyperconverged
What type of virtualization encapsulates computer programs from the underlying OS on which they are executed?
Application Virtualization

Second Level Address Translation (SLAT)

ARM
How much space does a barebones Windows installation take up?
