Hi All,
I have been tasked with configuring a high availability SQL installation for a client app that will connect to the database externally.
I will have no control over the client machines to make changes to DNS/IP's etc.
The SQL connection string for the clients is an external DNS name.
I will be using AlwaysOn to achieve this.
My main query is what happens if there is a loss of connectivity to site A (internet down) and I need to fail over to site B, meaning the DNS name now needs to point to the site B IP. Changes to DNS obviously take too much time to replicate and the changes need to be immediate.
What would be the best solution to get round this?
Thanks!
