Optimize an Azure Cosmos DB solution

You have an Azure Resource Manager (ARM) template that provisions Azure Cosmos DB accounts and databases. The accounts are deployed in a single Azure region. The databases use provisioned throughput. Template parameters define the region name, the database-throughput type, and the throughput value.

You need to modify some Azure Cosmos DB accounts and databases for these scenarios:

  • Scenario 1: Add a read region and increase database throughput.
  • Scenario 2: Change provisioned database throughput to autoscale.

The solution must minimize administrative effort and the time required for the modifications.

What should you use for each scenario?

Scenario 1:
Scenario 2:
Explanation

An incremental ARM deployment can update the Cosmos DB account's configured locations and the database's manual throughput in one deployment, while preserving resources not declared in the template. Migrating an existing database between manual provisioned throughput and autoscale is not supported by ARM templates; Azure PowerShell supports this throughput migration.
