Running XtraDB on Amazon Web Services?

I have 3 Servers running PXC on AWS.

I have 1 server running in each Availability Zone.

Amazon say they do maintenance on their boxes once a month and for about 30 minutes the server may go down. I don’t know, I have just started using them.

Has anyone experienced any issues with AWS from running a cluster stand point?

What if the Master goes down for about 30 minutes? What will this really affect.

I’m not too worried about 1 node going down for 30 minutes.


What do you mean by ‘master’? :slight_smile:
All depends on the workload and gcache size set. If the writes that happened in the cluster during these 30 minutes can still fit in gcache - the node that had maintenance will sync with the cluster using IST state transfer and will continue functioning.
