Cloud Computing Flashcards
On-Demand, self service, resource pooling, elastic, accessible and measurable are accepted characteristics of what?
Cloud computing
The on demand nature of what provides IT professionals the means to provision new servers, applications and other resources in a self service manner often within minutes of the request
Cloud computing
Blank, such as Amazon web services (AWS), Microsoft Azure, and GCP, purchase and manage vast quantities of computer storage and networking resources around the world
Cloud providers
Blank, often referred to as scalability, allows you to leverage cloud provider resources during busy months and recede back to your own data center for the rest of the year.
Elasticity
Services in the cloud must be what, which alludes to the way you pay for services in the cloud. You are charged for what you consume.
Measurable
Name three types of cloud service models
IaaS, PaaS, SaaS
Blank refers to the physical servers, storage, and networking that is required to exist before you can create any virtual servers or install any applications
Infrastructure
In the IaaS, who owns and maintains the underlying infrastructure.
Cloud provider
The three cornerstones of IaaS are?
Server virtualization, Storage virtualization, and network virtualization
In the IaaS model, who manages VM configuration, its operating system, and all the patches.
You do
In the IaaS model, who manages the hypervisor and the underlying hardware?
Cloud provider
Cloud providers are able to create what for each of their customers to keep networks isolated from each other?
Virtual Private Cloud (VPC) networks
In the PaaS model, the blank is responsible for the virtual servers and in some cases the servers that run on top of them.
Cloud provider
One example of PaaS is what?
Simple web hosting
What term is means that the consumer of the service typically is not even aware of the number of servers in the backend to run the application?
Serverless computing
PaaS solutions are attractive to who because it allows them to deploy their code to an application runtime environment that is backed by an ambiguous pool of computer resources
Application developers
What model of cloud service could represent nearly anything you consume over the internet?
SaaS
The differentiating factor in cloud deployment models is what?
Responsibility
What cloud deployment model is associated with equipment hosted within a single company’s on-premises data center?
Private
In the private cloud deployment model, if a failure occurs who is responsible for repairing the problem themselves?
The company
What is the term for a private cloud that is not hosted within the company’s data center?
Co-locating or Co-Lo solution
The ownership and control that a company has over the equipment is the primary advantage of what cloud deployment model?
Private
What cloud deployment model refers to the ownership and maintenance of the underlying infrastructure and facilities by a cloud service provider?
Public
What concept in public clouds means that multiple tenants share the same physical resources?
Multi-tenancy
What cloud deployment model is uncommon in the commercial sector, but may be found in universities and government agencies?
Community cloud
What cloud deployment model is most commonly associated with companies that extend their apps and services between their data center and that of a public cloud provider.
Hybrid Cloud
What cloud deployment model leverages the services of multiple cloud providers?
Multi-cloud
In the hybrid cloud deployment model, what is needed between the on-premises data center and the public cloud provider’s data center?
Virtual Private Network (VPN) Connection
