List Three Categories of Cloud Service Models? | Infrastructure as a Service (IaaS) |
Define Private Direct Connection? | They are private direct links between a Network and a Cloud Provider. |
Discuss how Classic Networking relates to Classic Computing? | The follow the same paradigm where a dedicated computing device with a dedicated Operating System performs each Netowrk function. |
Explain Desktop Virtualization and Virtual Desktop Infrastructure? | Desktop Virtualization requires Direct Access to a systems local desktop environment with a client that can access an OS running in a VM. |
What is the role of a Hypervisor? | The program used to create, run, and maintain the Virtual Machines. |
Describe Platform as a Service (PaaS)? | Gives some form of Infrastructure, but gets specific by building a Platform - a complete deployment and management system to handle every aspect of meeting some goal. |
Compare a Virtual NIC to a Physical NIC? | There's no difference once they are properly configured - They both have MAC Addresses, and you setup a vNIC as you would a pNIC. One is just Virtual and the other is a Hardware Card. |
Explain how Virtualization gives individual VMs valid IP Addresses by bridging the NIC? | Each bridge is a software connection that passes traffic from the real NIC to a vNIC. The bridge works at Layer 2 of the OSI Model, so each vNIC gets a legitimate unique MAC Address just as a pNIC would. |

Briefly describe why Service is the key to understanding the cloud? | We use the Servers and Networks of the Cloud through Layers of software that add great value (A Service) to the underlying hardware by making it simple to perform complex tasks or manage powerful hardware - without End Users needing to be responsible for maintaining it. |
Explain some scaling problems that occur as networked applications and services grow and mature? | As Services grow, you need more Programmers, and having tons of Programmers means they step on each others toes by making incompatible changes.
