Q

Platform as a Service (PaaS)

A

Somewhere between SaaS and IaaS. A typical PaaS solution would deploy servers and storage network infrastructure (as per IaaS) but also provide a multi-tier web application/database platform on top.

Q

Desktop as a Service (Daas)

A

Means of provisioning virtual desktop infrastructure (VDI) as a cloud service. VDI allows a client browser to operate an OS desktop plus software apps. This removes the need for an organization to deploy and maintain client PCs and software installs.

Q

Network functions virtualization (NFV)

A
  • A way to virtualize routers, firewalls, and load balancers
  • Extract network functions from hardware they ran on
  • Packaged as virtual machines (VMs)

Q

Virtual Network Function (VNF)

A
  • Run as VMs on standard server platforms.
  • Less epxensive and more flexible than specialized hardware
  • Specifies and deploys instances of each virtual appliance
  • Software implimentations of network functions

Q

Fibre Channel

A

-High speed communications protocol for SANs.
-1 to 128GFC (Gbps)

18
Q

Channel over Ethernet (FCoE)

A

-Fibre Channel packets over Ethernet cabling
-Allowing for a mixed use Ethernet network with LAN and SAN
-Requires special 10/40/100G adapters that combine the function of NIC and HBA,
-San

19
Q

Internet Small Computer System Interface (iSCSI)

A

-SAN
-IP tunneling protocol that enables the transfer of SCSI data over an IP-based network
-Inexpensive alternative to Fibre Channel

20
Q

North-South traffic

A

Traffic that flows into and out of a data center.

21
Q

East-West traffic

A

Communication between the different components of a data center.

22
Q

Private Cloud

A

Systems and users only have access with other devices inside the same private cloud or system

23
Q

Community Cloud

A

Collaborative effort where infrastructure is shared between several organizations from a specific community with common concerns

24
Q

Virtual Machine (VM) Escape

A

Occurs when an attacker breaks out of one of the isolated VMs and begins to directly interact with the underlying hypervisor

25
Q

Infrastructure as Code (IaC)

A

Enables managing and provisioning of infrastructure through code instead of through manual processes

26
Q

Private-Direct Connection

A

Extends preexisting, on-premise data center into the provider’s network to directly connect to your virtual private cloud network.

27
Q

Virtual Network Computing (VNC) Port 5900

A

*Designed for thin client
*Virtual Desktop Infrastructure (VDI)

28
Q
