AWS Aurora Global Database vs Azure Cosmos DB Multi-Region Failover

When building cloud-native applications requiring low latency across continents, choosing between AWS Aurora Global Database (Relational SQL) and Azure Cosmos DB (NoSQL / Multi-Model) depends on write traffic requirements and consistency guarantees.
