Define Cloud Models
- Cloud models define the deployment type of cloud resources.
- The three main cloud models are: Private Cloud, Public Cloud, and Hybrid Cloud.
Private Cloud
- A Private Cloud is a cloud used by a single entity, offering greater control.
- It can be hosted onsite in a corporate data center or offsite by a third party dedicated to the company.
- Provides higher control but comes with greater cost and fewer benefits than a public cloud.
Public Cloud
- Public Cloud is managed by a third-party provider, accessible to anyone who wants to purchase services.
- The main characteristic is the availability of resources to the general public.
Hybrid Cloud
- Hybrid Cloud integrates both private and public clouds.
- It offers flexibility, allowing organizations to scale up with public cloud resources during high demand.
- Provides extra security by allowing control over where data and applications are deployed (public vs. private).
The following table highlights a few key comparative aspects between the cloud models.
| Public cloud | Private cloud | Hybrid cloud |
|---|---|---|
| No capital expenditures to scale up | Organizations have complete control over resources and security | Provides the most flexibility |
| Applications can be quickly provisioned and deprovisioned | Data is not collocated with other organizations’ data | Organizations determine where to run their applications |
| Organizations pay only for what they use | Hardware must be purchased for startup and maintenance | Organizations control security, compliance, or legal requirements |
| Organizations don’t have complete control over resources and security | Organizations are responsible for hardware maintenance and updates |
Comparative Summary:
- Public Cloud: No capital expenditures, pay-as-you-go, quick provisioning, but lacks full control.
- Private Cloud: Complete control, no data colocation, but high startup costs and maintenance responsibilities.
- Hybrid Cloud: Flexibility to control security, compliance, or legal aspects; mixes public and private benefits.
Multi-cloud
- A Multi-cloud environment uses multiple public cloud providers.
- Allows organizations to benefit from different features across cloud providers.
- Requires management of resources and security across multiple cloud environments.
