The cost of storing 10 TB of data in Azure will depend on several factors, including the type of storage account you are using, the region where the data is stored, and the amount of data transfer required.
Assuming that you are using Azure Blob Storage for your cache storage account and DR region, the cost of storing 10 TB of data will depend on the type of storage account you choose. There are two types of Blob Storage accounts: Hot and Cool. Hot storage is designed for frequently accessed data, while Cool storage is designed for infrequently accessed data.
The cost of storing 10 TB of data in a Hot Blob Storage account will be higher than the cost of storing the same amount of data in a Cool Blob Storage account. As of September 2021, the cost of storing 10 TB of data in a Hot Blob Storage account in the US East region is $245/month, while the cost of storing the same amount of data in a Cool Blob Storage account is $105/month.
In addition to storage costs, there may be additional costs associated with data transfer between regions. The cost of data transfer will depend on the amount of data being transferred and the region where the data is being transferred to.
To get a more accurate estimate of the cost of storing 10 TB of data in Azure, you can use the Azure Pricing Calculator. This tool allows you to estimate the cost of various Azure services based on your specific usage patterns and requirements.
It will be determined based on what storage account type are you going to use, if you choose Premium, then the cost will be based on the provisioning capacity, while the standard is based on the consumption, more can be found here: https://learn.microsoft.com/en-us/azure/storage/files/understanding-billing
