AZ-900: Microsoft Azure Fundamentals
You plan to implement an Azure database solution.
You need to implement a database solution that meets the following requirements:
- Can add data concurrently from multiple regions
- Can store JSON documents
Azure Cosmos DB
Azure SQL
Azure Database for MySQL servers
Azure Database for PostgreSQL servers
SQL elastic pools
SQL Server stretch databases
Answer is Azure Cosmos DB
Azure Cosmos DB is Microsoft's globally distributed, multi-model database service. With a click of a button, Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure regions worldwide.
Azure Cosmos DB is a great way to store unstructured and JSON data. Combined with Azure Functions, Cosmos DB makes storing data quick and easy with much less code than required for storing data in a relational database.
