Virtualization and Cloud Computing Flashcards
A Hypervisor is a specialized software that enables virtualization to occur and emulates the physical hardware, this is also called a _________________.
Virtual Machine Monitor
VMWare’s _________________, Microsofts _________________, Virtual Box, and VMWARE _________________ are all popular hypervisors.
ESXi
Hyper-V
Workstation
There are two different types of Hypervisors, _________________ and _________________.
Type 1
Type 2
_________________ hypervisors have the OS sitting on top of the hypervisor which is sitting on top of the hardware.
Type 1
_________________ hypervisors have a hosted environment, you have an operating system sitting on top of hardware, and the hypervisor is sitting on top of this OS.
Type 2
A Type _________________ is better for servers.
1
The two types of virtual storage solutions are _________________ and _________________ .
Network Attached Storage Device (NAS)
Storage Area Network (SAN)
_________________ is a disk storage that is deliverd as a service over TCP/IP.
NAS
A _________________ is a specialized LAN designed for data transfer/storage. It transfers data at block level with special protocols. Most use special fiber-optic cables, used for heavy service area.
SAN
_________________ SAN is special purpose hardware that supplies 1-16 Gbps of storage area network speed.
Fibre Channel (FC)
_________________ is a SAN that removes the need for specialized hardware and runs your SAN over your Ethernet networks.
Fibre Channel over Ethernet (FCoE)
_________________ lowers the SAN cost and is built using Ethernet switches (<10 Gbps). It relies on configuration allowing jumbo frames (bigger than 1500 MTU’s) over the network.
iSCSI (IP Small Computer System Interface)
_________________ is a newer virtualized storage option using switched fabric topology for high-performance computing which comes with very hight throughput (>600 Gbps) and very low latencty (0.5 micro sectonds). Very expensivive, used in very large enterprise storage solutions.
Infiniband
_________________ overcomes the problem of all virtual servers being on one broadcast domain. Layer 2 control provides VLANs and trucking and provides Quality of Service and security.
Virtual Switches
_________________ is when a user’s desktop computer is run on a browser. These can be used from the web, laptop, tablet, or phone and is easier for the admins to secure and upgrade.
Virtual Desktops
_________________ provides the administrator with an easy to use front end to configure physical and virtual devices through the network. Lets you manage several switches or network devices from one central point.
Software-Defined Networking (SDN)
_________________ digitizes voice traffic so that it can be treated like other data on the network.
VoIP (Voice over IP)
VoIP uses _________________ to setup, maintain, and tear down calls.
SIP (Session Initiated Protocol)
VoIP can save a company money and provide enhanced services over a traditional phone system. Traditional phone systema are often referred to as _________________.
PBX or POTS
_________________ gives the ability to outsource your telephone system. Utilizes VoIP to send all data to a provider anywhere in the world, then the provider connects it to a telephone system.
Virtual Private Branch Exchange (PBX and VoIP)
VoIP is uses to setup, terminate, and tear-down the call using _________________, once the call is setup and being maintained, the actual voice traffic goes through the _________________.
SIP
RTP
