1. Describe Cloud Computing: Unit 5: Define Cloud Models Flashcards
What are cloud models?
Cloud models define the deployment type of cloud resources. The three main cloud models are private, public, and hybrid.
What is a private cloud?
A private cloud is a cloud environment used by a single entity, providing greater control but at a higher cost.
Where can a private cloud be hosted?
A private cloud may be hosted:
On-site in a company’s own datacenter
Offsite in a dedicated third-party datacenter
What is a public cloud?
A public cloud is built, controlled, and maintained by a third-party cloud provider. It is available to anyone who wants to purchase cloud services.
What is the key difference between public and private clouds?
A public cloud is available to the general public, while a private cloud is used by a single entity.
What is a hybrid cloud?
A hybrid cloud is a computing environment that combines public and private clouds in an inter-connected system.
How can a hybrid cloud handle temporary demand surges?
A hybrid cloud allows a private cloud to surge by deploying additional resources from the public cloud when needed.
How can a hybrid cloud enhance security?
A hybrid cloud allows organizations to flexibly choose which services to keep in the public cloud and which to deploy in their private cloud infrastructure.
What is a financial advantage of using a public cloud?
No capital expenditures to scale up; organizations pay only for what they use.
How does a public cloud handle application provisioning?
Applications can be quickly provisioned and deprovisioned.
Do organizations have full control over resources and security in a public cloud?
No, they don’t have complete control over resources and security.
What is a key advantage of a private cloud regarding security?
Organizations have complete control over resources and security.
How is data stored in a private cloud compared to a public cloud?
Data is not collocated with other organizations’ data.
What financial requirement is necessary for a private cloud?
Hardware must be purchased for startup and maintenance.
Who is responsible for hardware maintenance and updates in a private cloud?
The organization using the private cloud.
What is a major advantage of a hybrid cloud?
It provides the most flexibility.
How do organizations determine where to run applications in a hybrid cloud?
Organizations choose where to run their applications based on their needs.
How does a hybrid cloud benefit security, compliance, and legal requirements?
Organizations control security, compliance, or legal requirements.
What is a multi-cloud scenario?
A scenario where multiple public cloud providers are used.
Why might an organization adopt a multi-cloud strategy?
To use different features from different cloud providers or migrate from one provider to another.
What is a key challenge of managing a multi-cloud environment?
Managing resources and security across multiple cloud providers.
What is Azure Arc?
A set of technologies that helps manage cloud environments across public, private, hybrid, and multi-cloud setups.
Can Azure Arc be used in a multi-cloud environment?
Yes, it can manage multiple cloud providers at once.
How does Azure Arc benefit hybrid cloud environments?
It provides unified management for both on-premises and cloud resources.
