I run my website from EC2. Due to AWS outages, I am contemplating replicating my setup on Rackspace and switch over from DNS in case of an outage.
I am looking to learn ways to replicate my MySql database across these data centers.
Can someone educate me about the methodology, costs, advantages and pitfalls in this approach?
My site serves around 30K users per day with around 30 GB of Database data.
