google compute engine - Cloud SQL Connection + Auto Scaling -

-

per this, cloud sql requires external ip address of client in order allow connections it. other suggested way sql proxy big disclaimer method may change on time.

question: if auto scaling compute engine vms running webservers, need assign them external ips , go set in cloud sql instance? or missing huge? noob question perhaps, reading through.

the recommended way use cloud sql proxy (but if don't want use need add static ips gce vms , whitelist them on cloud sql instance).
