You have an Azure subscription. The subscription contains an app that is hosted in the East US, Central Europe, and East Asia regions.
You need to recommend a data-tier solution for the app. The solution must meet the following requirements:
* Support multiple consistency levels.
* Be able to store at least 1 TB of data.
* Be able to perform read and write operations in the Azure region that is local to the app instance.
What should you include in the recommendation?
Azure Cosmos DB approaches data consistency as a spectrum of choices. This approach includes more options than the two extremes of strong and eventual consistency. You can choose from five well-defined levels on the consistency spectrum.
With Cosmos DB any write into any region must be replicated and committed to all configured regions within the account
