LATEST UPDATE|ALREADY GRADED A+
IaaS ✔Correct answer-Infrastructure as a Service. A cloud computing technology useful fo r 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 ✔Correct answer-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 ✔Correct answer-Software as a Service. A subscription service where you purchase licenses
for software that expire at a certain date.
CaaS/UCaaS ✔Correct answer-(Unified) Communication as a Service
DBaaS ✔Correct answer-Database as a Service- offers full database functionality to application
developers
DaaS ✔Correct answer-Desktop as a Service
BPaaS ✔Correct answer-Business Process as a Service
XaaS ✔Correct answer-Anything as a Service
What are the four primary cloud delivery models? ✔Correct answer-Public
Private
Community
Hybrid
Public Cloud Delivery Model ✔Correct answer-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 ✔Correct answer-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 ✔Correct answer-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 ✔Correct answer-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 ✔Correct answer-Software that an organization's end users interact with
, Automation ✔Correct answer-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 ✔Correct answer-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 ✔Correct answer-Compute may refer to an IaaS service that lets you provision
virtual machines, storage, and networking resources in the cloud.
Computer FaaS ✔Correct answer-Compute can also refer to what the marketers call serverless
computing and what the technophiles call function-as-a-service (FaaS). In this mo del, the clou d
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. Instea d, the clou d
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 ✔Correct answer-National Institute of Standards and Technology
Colocation (COLO) ✔Correct answer-A data center that leases rack space to the general public
Data Center ✔Correct answer-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) ✔Correct answer-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 ✔Correct answer-A physical server that runs VMs
Machine Virtualization ✔Correct answer-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 (OS) called a guest OS. The software that
creates virtual machines and performs this abstraction is called a hypervisor.
network virtualization ✔Correct answer-Refers to virtual private clouds (VPCs)—isolated private
networks within the cloud that allow connectivity among virtual machines and othe r cloud
resources. There's some overlap with machine virtualization here, because VMs have virtual netwo rk
interfaces that connect to these virtual private clouds.
Hypervisor ✔Correct answer-Software that creates and manages virtual machines on a server or
on a local computer. Also called virtual machine manager (VMM).
