…Implementing Galera Cluster on Amazon EC2 provides several advantages for companies. Multi-master clustering comes out of the box as a default in Galera. Users can read and write from any database providing fast local writes and reads. Galera handles conflicts automatically if your application is writing to the same row. Nodes can be added and deleted on the fly if you need more capacity and elasticity. New nodes can join automatically.
