Which Azure service is considered a globally distributed database system?

Azure SQL Database
Azure Storage
Azure Cosmos DB
Azure Recovery Services

The correct answer is: Azure Cosmos DB

Azure Cosmos DB is regarded as a globally distributed database system due to its design and functionality that allows data to be replicated across multiple geographic regions. This service is built from the ground up to offer high availability and low-latency access to data, making it an excellent choice for applications that require global scale. Cosmos DB can automatically replicate your data across any number of Azure regions, which enables multi-region writes, supports multiple data models, and provides strong consistency and availability guarantees. In contrast, while Azure SQL Database is a powerful database service, it is not inherently designed as a globally distributed database system, as it primarily serves a single-region architecture unless you employ additional features like geo-replication. Azure Storage focuses on storing different types of data such as blobs, files, and queues, but it does not provide the database functionalities that Cosmos DB does. Azure Recovery Services is aimed at backup and disaster recovery solutions rather than acting as a database. Therefore, Cosmos DB uniquely meets the needs of applications that require a globally distributed database framework.
