Deploying Galera Clusters across WAN environments might lead to concerns around data privacy and security - especially as more organisations are having to comply with national and international regulations. You would not want hackers eavesdropping or intercepting replication traffic. Encrypted replication hides what is sent between the Galera nodes, and makes sure each node is only communicating to the ones it trusts. But how expensive is encryption?
In this blog, we will show you how to encrypt the replication traffic between your Galera nodes. We will also look into the performance impact of this encryption.

Galera supports SSL for the encryption of replication traffic. When encryption is enabled, Galera group communication and Incremental State Transfer (IST) happens over an SSL-encrypted …
