Difficulty: MediumCloud Deployment Models (Public, Private, Hybrid, Community)

Match each organizational IT infrastructure scenario on the left to its corresponding cloud deployment model on the right.

  • A financial firm maintains on-premises legacy databases while dynamically provisioning scalable web servers in an off-site environment during peak trading hours.Hybrid Cloud
  • An alliance of independent credit unions jointly funds and accesses a shared hosting platform designed specifically to meet mutual banking compliance rules.Community Cloud
  • A tech startup hosts its web services on shared multi-tenant infrastructure owned by a third party and pays strictly based on resource consumption.Public Cloud
  • A defense contractor utilizes dedicated computing hardware hosted at a third-party vendor facility isolated strictly for single-tenant organizational access.Private Cloud

Answer

The financial firm scenario matches Hybrid Cloud; the credit union alliance scenario matches Community Cloud; the tech startup scenario matches Public Cloud; and the defense contractor scenario matches Private Cloud.
Each deployment model is accurately categorized by its governance, ownership, and resource sharing characteristics: combining on-premises and off-site cloud bursting is Hybrid Cloud; joint infrastructure serving peer entities with common regulatory compliance needs is Community Cloud; multi-tenant pay-as-you-go infrastructure is Public Cloud; and dedicated single-tenant infrastructure—even when off-site—is Private Cloud.

Step-by-Step Solution

1
Identify the deployment model for combining private on-premises servers with external dynamic cloud capacity.
Bridging internal hardware with external cloud services forms a hybrid architecture.
A hybrid cloud combines two distinct cloud structures (such as private and public) to share data and applications.
2
Identify the deployment model for joint infrastructure shared by organizations with common regulatory mandates.
Shared infrastructure among specific member institutions with joint requirements constitutes a community deployment.
Community clouds exist specifically for organizations sharing joint goals, regulatory requirements, or security concerns.
3
Identify the deployment model for multi-tenant, pay-as-you-go services operated by a third-party vendor.
Commercial multi-tenant hosting available to general businesses represents a public cloud.
Public clouds render resources over the open internet to multiple tenants who share underlying physical hardware.
4
Identify the deployment model for dedicated, single-tenant off-premises hardware.
Exclusive hardware dedicated solely to one organization represents a private cloud.
A private cloud guarantees single-tenant usage and exclusive ownership of resources, whether located internally or managed externally.
