Difficulty: MediumCloud Models (Public, Private, Hybrid, Multi-cloud)

A municipal transit agency manages its core scheduling software on physical servers located in its local data center. The agency plans to build a new real-time bus tracking application on Microsoft Azure to handle sudden spikes in passenger queries. The tracking application must retrieve schedule updates from the local servers. Which cloud deployment model is represented by this scenario?

  1. A
    Private cloud
  2. Hybrid cloudAnswer
  3. C
    Public cloud
  4. D
    Platform as a Service (PaaS)

Answer

Hybrid cloud
A hybrid cloud model combines on-premises infrastructure (or a private cloud) with a public cloud (such as Microsoft Azure), allowing data and applications to be shared between them. In this scenario, the agency keeps its core scheduling software on physical local servers while running its public tracking application on Microsoft Azure.

Step-by-Step Solution

1
Analyze the infrastructure components described in the scenario.
The agency uses both physical servers in its local data center (on-premises/private) and Microsoft Azure (public cloud) to host its systems.
Determining where resources are located is the first step to identifying the cloud deployment model.
2
Evaluate the interaction between the environments.
The public tracking application hosted on Azure must retrieve data from the physical local servers, demonstrating integration and data sharing between the environments.
A deployment that connects private on-premises infrastructure with a public cloud is classified as a hybrid cloud model.
