With the widespread adoption of cloud services, it has become critical for businesses to accurately estimate the cost of deploying and managing services in the cloud. Microsoft Azure provides two significant tools for estimating these costs: the Pricing Calculator and the Total Cost of Ownership (TCO) Calculator. Both have their unique strengths and approaches to cost estimation.
1. Azure Pricing Calculator:
Microsoft Azure’s Pricing Calculator is an interactive tool that allows potential clients to accurately predict the cost of their usage of various Azure services. The pricing calculator derives costs based on the resources actually used like storage, number of transactions, and outbound data transfers. The calculator also takes into account factors such as region, reserved instances, and Azure Hybrid benefits.
Using the Pricing calculator is quite straightforward. You simply specify the Azure resources you plan to use and configure details specific to the resource. The calculator then provides an estimated monthly cost for the use of the specified resources.
Here is an example of how to use the Azure Pricing Calculator:
- Select the “Products” tab.
- In the search box, type the name of the product, for instance, “App Service.”
- Select the configured product, e.g., “App Service.”
- Specify the appropriate settings, such as region, tier, and instance hours.
- Finally, click “Add to my estimate.” the tool computes and displays a monthly cost figure.
2. Total Cost of Ownership (TCO) Calculator:
While the Pricing Calculator provides estimated costs of using specific Azure services, the TCO Calculator provides a holistic view of the costs of running your entire IT infrastructure on Azure.
This tool compares the cost of running your applications, data, and infrastructure in an on-premises or co-located data center versus running them in the Azure cloud. It takes into account various cost factors, such as server and network hardware, power and cooling, software licenses, and IT labor.
Here is an example of how to use the TCO calculator:
- Select the “Start” button.
- Fill in details about your on-premises infrastructure, such as the number of servers, storage space, and network devices.
- Fill in details about your IT labor costs, such as FTEs and salaries.
- Click “Next” and fill in details about your application, database, and storage costs.
- Click “Next” to get the TCO report. The tool will present a detailed comparison between your current infrastructure costs and projected costs if you migrate to Azure.
Comparing Azure Pricing Calculator and TCO Calculator:
While both the Pricing Calculator and the TCO Calculator are powerful tools for cost estimation, they cater to different needs in the cost estimation landscape. The Pricing Calculator is more appropriate when you have a clear idea of the Azure resources you plan to use and want an accurate estimate of the costs of these resources. On the other hand, the TCO calculator is more effective when you want to compare the cost of migrating your entire IT operations to Azure versus keeping them on-premises.
| Azure Pricing Calculator | Total Cost of Ownership Calculator |
|---|---|
| Resource-specific costs | Holistic IT infrastructure costs |
| Detailed cost estimates of specific Azure resources | Comparison between on-premises and Azure costs |
| Resource usage, region, reserved instances, Azure Hybrid benefits | Hardware, power and cooling, software licenses, IT labor |
In conclusion, both the Pricing Calculator and the TCO Calculator offer crucial insights for businesses planning to adopt or expand their use of Azure. The choice between the two boils down to the specific cost estimation needs of your organization.

Interview Questions
What is a Microsoft Azure regional pair?
A regional pair consists of two Microsoft Azure regions within the same geography (for example, the US, Europe, or Asia). The two regions are at least 300 miles apart and are directly connected by Microsoft’s high-speed, private network to help ensure data residency, sovereignty, compliance, and resiliency.
What are Azure sovereign regions?
Azure sovereign regions are physically isolated instances of Microsoft Azure. These include Azure Government, Azure China 21Vianet, and Azure Germany. They adhere to strict regulations, standards, and policies of their respective government entities.
What is the advantage of using region pairs in Azure?
Region pairs in Azure offer benefits such as data residency, disaster recovery and high availability. If there’s a region-wide service disruption, one region out of every pair is prioritized to ensuring applications that are deployed across paired regions remain available.
How does Azure handle planned maintenance when it comes to regional pairs?
Azure ensures that not both regions in a pair undergo planned maintenance at the same time, thereby minimizing the downtime.
What are Azure regions?
Azure regions are geographically dispersed data centers across the world. They provide high availability, reliability, and scalability to Azure services.
How many Azure regions are there worldwide?
As of November 2021, Azure has 60+ regions worldwide, more than any other cloud provider.
What are Azure geographies?
An Azure geography is a defined area of the world that contains at least one Azure region. They ensure that data residency, sovereignty, compliance, and resiliency requirements are honored within geographical boundaries.
How is data replicated across Azure regions?
Azure Storage Service provides a range of options for replicating data, including locally redundant storage (LRS), zone-redundant storage (ZRS), geo-redundant storage (GRS), and read-access geo-redundant storage (RA-GRS).
Can users select any Azure region for deploying their resources?
Yes, users can generally choose any region for deploying their resources, but availability may depend on the specific Azure services and the user’s subscription type.
How does Azure ensure that data remains within a specific geography?
Azure ensures data residency by not replicating data to other geographies unless users explicitly opt for geo-redundant storage. For sovereign regions, Azure guarantees data will always remain within the borders of that country.
