Configuring multiple data centers

Updated on May 17, 2024

This content applies only to On-premises and Client-managed cloud environments

Ensure the continuity of your online services by adding a secondary Cassandra data center.

Configuring your application to take advantage of multiple data centers improves performance and prevents downtime, because you can have multiple copies of data saved across the separate physical locations that host your application servers.
Before you begin:
  • Disable decision services in the primary data center (DC1), and the secondary data center (DC2).
  • Ensure that DC1 and DC2 communicate directly through ports 7000 and 9042.
Follow these steps to add a secondary data center in the active-active configuration. In the active-active configuration, both data centers run the same services simultaneously, to effectively manage the workload across all nodes and minimize application downtime.
