Explanation

Azure Cosmos DB is a multi-model globally distributed NoSQL database. Cosmos DB stores data in atom-record-sequence (ARS) format. It unites under one roof several data management systems and exposes them as APIs. You can select between the Core (SQL) API and MongoDB API (document model), Cassandra API (column-oriented model), Gremlin API (graph model), and Table API (key-value model). Azure CosmosDB provides high availability in two primary ways: replication data across regions and storing four copies of the data in a region. By default, Azure CosmosDB is distributed in all Azure regions. You can change the number of regions in your CosmosDB account. Suppose you associate five Azure regions with your data, and every region will have four copies of the data. There will be twenty copies of your data available to use. https://docs.microsoft.com/en-us/azure/cosmos-db/high-availability
