Successfully competing in today’s market is hard enough without having to worry about whether a critical application — your mobile app if you’re a retailer or a bank, or a shipping provider tracking packages and vehicles — will go down. A better approach is deploying your app and database across multiple data centers, then synchronizing the database instances to survive a data center outage.
Replicating a database across regions enables business continuity in case of a disaster by enabling the app to instantly connect with a region that is running.
With Cassandra, it’s possible to specify which data can stay in the country and which data can be replicated elsewhere.
It enables the spinning up of a database with the ability to scale up and down automatically in multiple regions — all with a few clicks — to support disaster recovery, data sovereignty and latency requirements.
