 Active-Active databases allow read and write operations in each copy.  Each copy eventually reflects changes made in other copies ([eventual consistency]({{< relref "/glossary#eventual-consistency" >}})).  Conflict-free data types (CRDTs) synchronize read and write operations between copies.  CRDTs ensure consistency and resolve conflicts.
 
+Active-Active databases use TLS to synchronize data between regions.  You can also use TLS to encrypt client connections.  See [Transport Layer Security (TLS)]({{< relref "/operate/rc/security/database-security/tls-ssl.md" >}}) for more information.

 When developing for Active-Active databases, you need to consider some important differences. See [Develop applications with Active-Active databases]({{< relref "/operate/rs/databases/active-active/develop/_index.md" >}}) for related information.

 We strongly recommend enabling TLS for any application transmitting sensitive data across the wire.
