A company is evaluating its deployment strategy for two workloads:

- Workload 1: A proprietary database hosted on dedicated physical hardware that the company leases and manages inside a third-party vendor's datacenter. The hardware is not shared with any other tenants.
- Workload 2: A customer portal hosted on shared virtual machines on Microsoft Azure.

The company establishes a secure virtual private network (VPN) connection between the two workloads to allow database queries from the customer portal.

Which cloud model represents the hosted environment of Workload 1, and which cloud model represents the combined architecture of both workloads?

Cevabı ve açıklamayı göster

Cevap: Workload 1 is hosted in a private cloud, and the combined architecture is a hybrid cloud.

Cevap

Workload 1 is hosted in a private cloud, and the combined architecture is a hybrid cloud.
The correct option is the one stating that Workload 1 is hosted in a private cloud and the combined architecture is a hybrid cloud. Workload 1 is a private cloud because it is built on dedicated hardware used exclusively by one organization, regardless of the fact that it is hosted in a third-party datacenter. The combined environment is a hybrid cloud because it establishes network connectivity and data sharing between this private cloud and Microsoft Azure, which is a public cloud.

Adım Adım Çözüm

1
Analyze Workload 1 infrastructure ownership and access model.
Since the physical hardware is dedicated exclusively to one tenant and not shared, it is classified as a private cloud, despite being physically located in a third-party vendor's datacenter.
Private clouds can be hosted either in an on-premises datacenter or by a third-party service provider, as long as the organization has exclusive use of the isolated hardware.
2
Analyze Workload 2 deployment model.
Workload 2 runs on shared virtual machines on Microsoft Azure, which is a public cloud provider.
Public cloud services are owned and operated by a third-party cloud provider and share resources among multiple tenants.
3
Evaluate the combined architecture connecting Workload 1 and Workload 2.
The integration of a private cloud (Workload 1) and a public cloud (Workload 2) via a VPN connection results in a hybrid cloud model.
Hybrid cloud is defined by the combination of public and private cloud models, enabling data and applications to be shared and communicated between them.
