Microsoft Azure Fundamentals
Where there is not a common pool to share among different companies as there is in a public cloud, what is the disadvantage of a private cloud
Increased cost
A private cloud consists of cloud computing resources used
*exclusively* by one business or organization
*Ease*—transitioning to the cloud doesn't have to be overwhelming because you can migrate
*gradually*—phasing in workloads over time.
*More scalability*—private clouds often offer more scalability compared to
*on-premises* infrastructure
The private cloud can be located/hosted where? (2)
*physically* at your organization's *on-site* datacenter *hosted* by a *third-party* service provider.
*Control*—your organization can maintain a
*private infrastructure* for sensitive assets or workloads that require *low latency*
The most common type of cloud computing deployment
*public* clouds
With public clouds, the cloud resources (like servers and storage) are owned and operated by a
*third-party* cloud service provider and delivered over the internet
A hybrid cloud platform gives organizations many advantages—such as... (5)
- greater flexibility - more deployment options - security - compliance - getting more value from their existing infrastructure.
*Four* Advantages of the Hybrid Cloud
Control Flexibility Latency Ease
A private cloud can make it easier for an organization to customize its resources to meet specific
IT requirements
*Four* Advantages of Public Clouds
Lower costs No maintenance Near-unlimited scalability High reliability
*Three* Advantages of a Private Cloud
More flexibility More control More scalability
*Cloud Model Comparison* (contrast) Public Cloud: • • • Private Clouds: • • • Hybrid Clouds: • • •
Public: • No capital expenditures to scale up. • Applications can be quickly provisioned and deprovisioned. • Orgs pay for only what they use. Private: • Hardware must be purchased for start-up & maintenance. • Orgs have complete control over resources & security. • Orgs are responsible for hardware maintenance & updates. Hybrid: • Provides the most flexibility. • Orgs determine where to run their applications. • Orgs control security, compliance, and legal requirements.
Hybrid cloud computing
combines on-premises infrastructure—or a private cloud—with a public cloud. Hybrid clouds allow data and apps to move between the two environments.
Microsoft Azure is an example of a ........ cloud, and Microsoft is a cloud what?
public service provider
*Flexibility*—you can take advantage of additional
resources in the public cloud *when you need them*
Edge computing brings the computing power of the cloud to IoT devices—closer to where the
data resides.
In a private cloud, the hardware and software are
dedicated solely to your organization.
The hybrid cloud is evolving to include ______ workloads as well.
edge
Public cloud deployments are frequently used to provide web-based..... (4) environments.
email online office applications storage testing & development
*No maintenance*—your .............. provides the maintenance.
ervice provider
*Cost-Effectiveness*—with the ability to scale to the public cloud, you pay for
extra computing power *only when needed*
*High reliability*—a vast network of servers ensures against
failure
Organizations gain the _________ & _________ the public cloud provides by running certain workloads in the cloud while keeping highly sensitive data..... (where?)
flexibility and innovation in their own datacenter to meet client needs or regulatory requirements.
In a public cloud, you share the same (what 3 things?) with other organizations or cloud "tenants"
hardware storage network devices
*Lower costs*—no need to purchase .... or ...., and you pay only for
hardware or software the service you use.
*More control*—resources are not shared with others, so
higher levels of *control and privacy* are possible
By moving workloads to the edge, devices spend less time communicating with the cloud, reducing _______, and they are even able to operate reliably in extended ______ _______.
latency offline periods
Hybrid cloud computing also eliminates the need to make *massive capital expenditures to handle short-term spikes in demand*, as well as when the business needs to free up.....
local resources for more sensitive data or applications
*More flexibility*—your organization can customize its cloud environment to
meet specific business needs
Cloud computing is a model for enabling ........... access to a ......... ......... of configurable computing resources, such as servers, networking, storage and apps and services.
on demand shared pool
*Near-unlimited scalability*— ............ resources are available to meet your business needs.
on-demand
In a private cloud, the services and infrastructure are always maintained on a
private network
When computing and processing demand fluctuates, hybrid cloud computing gives businesses the ability to seamlessly..... without giving third-party datacenters.....
scale up their on-premises infrastructure to the public cloud to handle any overflow access to the entirety of their data.
With a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by
the cloud provider
Cloud Computing
the delivery of computing services over the internet, enabling faster innovation, flexible resources, and economies of scale.
Another disadvantage of a private cloud if that not nearly all the services that are available in a public cloud like Azure are available since in a private cloud
the isolated company must provide all that.
In a public cloud, you access services and manage your account using a
