What is the advantage of using multi-region replication with Azure Cosmos DB?

Using multi-region replication with Azure Cosmos DB significantly enhances availability, which is a critical feature for modern applications. When data is replicated across multiple regions, it ensures that there is a consistent copy of data available in various geographical locations. This means that even if one region experiences downtime or network issues, the application can continue to operate normally by accessing data from another region.

Furthermore, by leveraging multi-region replication, you can also achieve lower latency for users since they can connect to the nearest replica of the database. This is especially important for global applications where user experience is contingent on quick access to data. Thus, the primary advantage of using multi-region replication is that it provides high availability and resilience, safeguarding applications against outages and promoting uninterrupted services.
