Describe Cloud Concepts (20-25%) Flashcards
Which Cloud model best describes “Services are offered over the public internet and available to anyone who wants to purchase them. Cloud resources, such as servers and storage, are owned and operated by a third-party cloud service provider, and delivered over the internet”?
Public Cloud
Which Cloud model “consists of computing resources used exclusively by users from one business or organization. Can be physically located at your organization’s on-site (on-premises) datacenter, or it can be hosted by a third-party service provider.”?
Private Cloud
Which Cloud model “is a computing environment that combines a public cloud and a private cloud by allowing data and applications to be shared between them.”?
Hybrid Cloud
Which BENIFIT of the cloud can be summarized as “Depending on the service-level agreement (SLA) that you choose, your cloud-based apps can provide a continuous user experience with no apparent downtime, even when things go wrong.”
High Availability
Which BENIFIT of the cloud can be summarized as
“increase compute capacity by adding RAM or CPUs to a virtual machine
Scaling vertically
Which BENIFIT of the cloud can be summarized as
“increases compute capacity by adding instances of resources, such as adding VMs to the configuration.”
Scaling Horizontal
Which BENIFIT of the cloud can be summarized as
” cloud-based apps to take advantage of autoscaling, so your apps always have the resources they need”
Elasticity
Which BENIFIT of the cloud can be summarized as
“Deploy and configure cloud-based resources quickly as your app requirements change
Agility
Which BENIFIT of the cloud can be summarized as
“deploy apps and data to regional datacenters around the globe, thereby ensuring that your customers always have the best performance in their region
Geo-distribution
Which BENIFIT of the cloud can be summarized as
“cloud-based backup services, data replication, and geo-distribution, you can deploy your apps with the confidence that comes from knowing that your data is safe in the event of disaster.”
Disaster Recovery
Which Expenditure type is
“up-front spending of money on physical infrastructure, and then deducting that up-front expense over time. The up-front cost of assets has a value that reduces over time.”
Capital Expenditure
Which Expenditure type is
“is spending money on services or products now, and being billed for them now. You can deduct this expense in the same year you spend it. There is no up-front cost, as you pay for a service or product as you use it.”
Operational Expenditure
Cloud service providers operate on a ______ model which means that end users only pay for the resources that they use
consumption
Which Cloud Service model
“is the closest to managing physical servers; a cloud provider will keep the hardware up-to-date, but operating system maintenance and network configuration is up to you as the cloud tenant.”?
Infrastructure as a service (IaaS)
Which Cloud Service Model
“is a managed hosting environment. The cloud provider manages the virtual machines and networking resources, and the cloud tenant deploys their applications into the managed hosting environment”
Platform as a service (PaaS)
