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
