This article will walk you through the principles and processes of picking a suitable billing model, thereby contributing to your ability to configure and operate a Hybrid Cloud.
Azure Stack Hub supports two billing models: the Consumption-based model and the Capacity-based model. Your choice between these two will significantly impact how your cloud services are billed and managed.
1. Consumption-based Model:
In a consumption-based model, customers are billed according to their actual usage. This means your costs are directly proportional to the resources you’re using, such as VMs, storage, and networking. Hence, if you are utilizing fewer resources, you will be billed less and vice versa.
This model’s advantage is that it offers large-scale flexibility, allowing users to scale up and down based on their requirements. Paying for what you use also aids in cost optimization. However, it might be tricky to predict costs accurately since it varies with resource usage.
2. Capacity-based Model:
This model charges a fixed fee for Azure Stack Hub that provides unlimited Azure services usage. Whether you utilize resources to their full potential or not, your billing remains constant.
The capacity-based model simplifies cost prediction and budgeting because of its fixed rate. However, it may lead to cost inefficiency if the resources are underutilized.
Making the Choice:
The key to picking between these two models lies in your utilization pattern and business needs. If your usage is predictable and continuous, the capacity-based model may be more cost-efficient. Alternatively, for dynamic needs with significant usage ups and downs, the consumption-based model could be more suitable, as it offers the flexibility to pay for what you use.
For instance, if you are running an e-commerce platform that experiences higher traffic during holiday seasons, the consumption-based model allows you to ramp up resources during high-demand periods and scale down during off-peak times.
In contrast, if you’re operating an organization with constant high-demand like a large-scale IT company, choosing a capacity-based model might be more beneficial.
To configure your chosen billing model in Azure Stack Hub, follow these steps:
- Navigate to the Azure Stack Hub user portal.
- In the left pane, click on ‘Billing’ and select ‘Configuration.’
- Select the desired billing model from the drop-down menu.
The Microsoft Azure Stack Hub offers flexibility and control over your resource utilization and billing. Depending on your business needs and resource usage patterns, you can choose between the capacity or consumption-based model. Familiarity with these billing models forms a key part of your AZ-600 Exam journey. Always ensure to choose the model that aligns best with your organizational goals and budgeting needs.
By granting the ability to select a suitable billing model, Azure Stack Hub provides an optimization tool for managing cloud expenditures. It does not only facilitate cost savings but also allows resources alignment with organizational requirements. Understanding these models helps you navigate cost management more effectively, paving the way for success in the AZ-600 Exam.

Capacity-based model and pay-as-you-use model are two options for Azure Stack Hub deployment: True/False?
– True
– False
Answer: True
Explanation: Azure Stack Hub offers the flexibility of two pricing models – Capacity model that offers fixed fee, suitable for predictable workloads and Pay-as-you-use model for unpredictable or timed workloads.
Microsoft does not provide any assistance on selecting a billing model: True/False?
– True
