Load Balancing AWS RDS MySQL read traffic using Route53 Weighted Routing
Randika Rathugamage

Hi! I tried using this method, but our php containers in ECS kept getting random connection errors, where the connection could not get established.

I apologise for not being able to to provide any substantial “proof” that this what was caused by this type of read load balancing, but problem was resolved by addressing the read replica directly in our application.s
