Xeround have just informed me that they are discontinuing their public cloud offering and given us 2 weeks to migrate. Our system went live less than 2 months ago and I am now in a panic.
Can anyone recommend an alternative that is likely to be easy to migrate to.
Quick and easy would be to migrate to Amazon RDS. You'll lose some availability (15 minute downtime due to hardware failure vs. none with Xeround), but unless your database is exceptionally large, it should be a fairly painless migration.
Amazon RDS supports MySQL, and has options for read replicas and failover configurations that might mitigate the availability issue.
