Q

Cloud Computing Components

A

Resource Allocation
Rapid Elasticity
Resource Pooling
On-demand Self-service
Measured Service

17
Q

Rapid Elasticity

A

Refers to the systems ability to handle changes in demand in real-time.

18
Q

Measured Service

A

A providers (Microsoft, Amazon etc) ability to control and bill a customers use of resources.

19
Q

Common Cloud Models

A

Private Cloud (On-Premise, hosted by companies themselves)

Public Cloud (Azure, AWS.. You share the providers resources with other companies)

Community Cloud (Where multiple tenants share a private pool of resources; Dentists of America etc)

Hybrid Cloud (Private/Public combined)

20
Q

IaaS

A

Infrastructure as a Service

A cloud model wherein the client makes use of a providers hardware to establish their own virtual network, spinning up servers/data centres etc.

Eg; Microsoft Azure, AWS, GoDaddy, WordPress

21
Q

SaaS

A

Software as a Service

A cloud model wherein the client makes use of a providers software for use in their enterprise environment

Eg; Office 365, DropBox, Gmail, SalesForce

22
Q

PaaS

A

Platform as a Service

A cloud model wherein the client utilizes fully pre-configured systems from the provider, and passes the maintenance responsiblities to the provider.

Eg; Microsoft Azure, AWS

23
Q

IaaS Components

A

Server, Storage, Network.

Used by Infrastructure Architects

24
Q

SaaS Components

A

Server, Storage, Network, OS & Middleware, Packaged Software

Used by End-Users

25
Q

PaaS Components

A

Server, Storage, Network, OS & Middleware

Used by Software Developers

26
Q

Cloud Providers

A

Microsoft Azure
AWS
Google Cloud
IBM Cloud
Oracle Cloud Infrastructure

27
Q

VDI

A

Virtual Desktop Infrastructure

Using a VM as a way to provision and manage corporate desktops

28
Q

VDE

A

Virtual Desktop Environment

The virtual desktop/workspace used by end-users

29
Q

Thin Client

A

Low-spec PC intended for remote access to a VM for use by employees / end users

30
Q

Application Virtualization

A

Instead of running the entire end-user desktop in a VM, they access an application hosted on a server or stream the app.

31
Q

Virtual Application Streaming

A

Just enough of the program is installed on the end-user device to utilize both the external hardware, and the desktops own.

32
Q

Container Virtualization

A

Enforces separation at the application & resource use level by creating separate instances of OS’s for use by end-users.

33
Q

SDN

A

Software Defined Networking

A software based network environment that can imitate hardware networks in a virtual infrastructure.

Utilizes Data & Control planes to virtualise NAT, packet analysis etc…

34
Q

Planes of Operation in Network Devices (Routers, Switches etc…)

A

Data, Control & Management

35
Q

Application Layer / Management Plane

A
  • Configure and manage the device
  • SSH, API, Browser…
36
Q

Control Layer / Control Plane

A

The part of a network that controls how data is forwarded, while the data plane or forwarding plane is the actual forwarding process.

  • Manages the actions of the Infrastructure Layer / Data Plane
  • Routing tables, session tables, NAT
  • Used in SDN (Software Defined Networking)
37
Q

Control Layer / Control Plane

A

The part of a network that controls how data is forwarded, while the data plane or forwarding plane is the actual forwarding process.

  • Manages the actions of the Infrastructure Layer / Data Plane
  • Routing tables, session tables, NAT
  • Dynamic routing protocol updates
  • Part of Software Defined Networking (SDN)
38
Q

Infrastructure Layer / Data Plane

A

The infrastructure layer enables a software system to interact with external systems by receiving, storing and providing data when requested.

  • Processes the network frames & packets
  • Forwarding, trunking, encryption & NAT
  • Part of SDN (Software Defined Networking)
