Identifying the Expenditure Model for Migrating Virtual Machines to Azure
Question
You have 1,000 virtual machines hosted on the Hyper-V hosts in a data center.
You plan to migrate all the virtual machines to an Azure pay-as-you-go subscription.
You need to identify which expenditure model to use for the planned Azure solution.
Which expenditure model should you identify?

One of the major changes that you will face when you move from on-premises cloud to the public cloud is the switch from capital expenditure (buying hardware) to operating expenditure (paying for service as you use it). This switch also requires more careful management of your costs. The benefit of the cloud is that you can fundamentally and positively affect the cost of a service you use by merely shutting down or resizing it when it's not needed.

Explanation: In this scenario, the company plans to migrate 1,000 virtual machines to an Azure pay-as-you-go subscription. Therefore, the expenditure model they should use is the operational expenditure (OpEx) model.
Operational expenditure is the cost incurred in the regular operations of a business, such as the cost of electricity, wages, rent, and other day-to-day expenses. In the context of cloud computing, operational expenditure refers to the cost of using cloud services on a pay-as-you-go basis. This model allows organizations to pay only for what they use and avoid the upfront capital expenditure required for on-premises infrastructure.
On the other hand, capital expenditure (CapEx) refers to the cost incurred in acquiring or upgrading assets such as hardware, software, or real estate. In the context of cloud computing, this would refer to the upfront costs associated with building and maintaining an on-premises data center.
Scalable and elastic expenditure models are not relevant to this question as they refer to the ability of a cloud service to dynamically adjust its resources based on demand. While this is an important feature of cloud services, it is not related to the expenditure model used.
In summary, the best option for the expenditure model in this scenario is the operational expenditure (OpEx) model, as it allows the company to pay for cloud services on a pay-as-you-go basis without incurring upfront capital expenditure.
