In the context of building a cross region disaster recovery plan for RDS [MySQL] I read this article .
It states :
- Configure alerts to identify errors in sync between the two regions. Amazon RDS is an excellent resource, but it does fail. Configuring alerts using a service like Amazon SNS will keep you abreast of any issues and enable you to keep a synchronized, operational recovery site.
What would such an alert be?
Would it be the ReplicationLag metric from Cloudwatch?
