Question

A retail company runs a globally distributed order-processing application backed by Azure Cosmos DB. The business requires that the application continue accepting new orders (writes) with near-zero downtime even if an entire Azure region becomes unavailable, and they cannot tolerate any manual failover steps that delay write availability. Which Cosmos DB configuration best meets these requirements?

Accepted Answer

Configure the account with multiple write regions (multi-region writes) across the regions where the application is deployed.

Answer

Configure a single-region write account with a second read region and enable automatic failover.

Answer

Configure a single-region account and rely on periodic Cosmos DB backups restored to a paired region during an outage.

Answer

Configure a single-region write account and use Azure Traffic Manager to route write traffic to a read replica.
