CMIT-326 CLOUD TECHNOLOGIES | STUDY GUIDE
IaaS - Answers - Infrastructure as a Service. A cloud computing technology useful for
heavily utilized systems and networks. Organizations can limit their hardware footprint
and personnel costs by renting access to hardware such as servers. Compare to PaaS
and SaaS.
PaaS - Answers - Platform as a Service. Provides cloud customers with an easy-to-
configure operating system and on-demand computing capabilities. Compare to IaaS
and SaaS.
SaaS - Answers - Software as a Service. A subscription service where you purchase
licenses for software that expire at a certain date.
CaaS/UCaaS - Answers - (Unified) Communication as a Service
DBaaS - Answers - Database as a Service- offers full database functionality to
application developers
DaaS - Answers - Desktop as a Service
BPaaS - Answers - Business Process as a Service
XaaS - Answers - Anything as a Service
What are the four primary cloud delivery models? - Answers - Public
Private
Community
Hybrid
Public Cloud Delivery Model - Answers - The public cloud is designed for use by the
general public. It is the utility-based pay-as-you-go model.
Private Cloud Delivery Model - Answers - A private cloud is for the exclusive use of a
single organization, but it may be used by many units or entities inside a company.
Community Cloud Delivery Model - Answers - Community clouds are offered for a
specific community of interest and shared by companies with similar requirements for
regulatory compliance, security, or policy.
Hybrid Cloud Delivery Model - Answers - A hybrid cloud is what you get when you
connect multiple cloud infrastructures that may or may not be of the same type (public,
private, or community).
, Application - Answers - Software that an organization's end users interact with
Automation - Answers - Automates the deployment and monitoring of cloud resources,
including network, storage, and compute. Automation makes rapid deployment and
teardown possible, and it gives users granular control over their cloud usage.
Compute - Answers - Cloud services that run your applications fall under the category of
compute. Compute may refer to one of two things: IaaS virtual machines, or so-called
serverless computing.
Compute IaaS - Answers - Compute may refer to an IaaS service that lets you provision
virtual machines, storage, and networking resources in the cloud.
Computer FaaS - Answers - Compute can also refer to what the marketers call
serverless computing and what the technophiles call function-as-a-service (FaaS). In
this model, the cloud provider hands you a slick interface into which you can upload
your own application code written in a variety of programming languages, and the cloud
provider executes it on compute infrastructure that they fully manage. This model
obviates the need to provision virtual machines. Instead, the cloud provider handles the
compute infrastructure, so all you have to do is deal with the application code. FaaS is a
type of PaaS offering.
NIST - Answers - National Institute of Standards and Technology
Colocation (COLO) - Answers - A data center that leases rack space to the general
public
Data Center - Answers - A specialized facility designed to hold and protect computer
systems and data. This would include racks, generators, massive HVAC, and internet
connectivity
Cloud Service Provider (CSP) - Answers - In addition to providing and managing the
data center infrastructure, a cloud service provider (or just provider for short) also
handles the IT hardware infrastructure—namely servers, storage, and networking. The
consumer of the cloud services pays fees to use the provider's equipment, and such
fees are typically based on usage and billed monthly. In this lesson, we'll dive further
into the details of how cloud computing works and how an organization might use the
cloud instead of—or in addition to—a traditional data center or colo model.
Virtualized Host - Answers - A physical server that runs VMs
Machine Virtualization - Answers - Also called server virtualization—involves abstracting
the resources of a single physical server into multiple virtual machines (VMs).
Essentially, a VM is a software-emulated computer consisting of virtual CPUs (vCPUs),
memory, storage, and networking. Like a real computer, a VM runs an operating system
