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
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.
