Hey there,

You can enable private networking on your Managed Database to enable connectivity over the private network instead of the public network! You’d just need to use the private connection string from a Droplet with private networking enabled in the same datacenter as your cluster.

Ok great! So then no communication between the two would be counted against the transfer limit? And the transfer limit would only be counted against when data leaves my droplet outside the private network?

Say a user requests data from my db. He would call my droplet api, my droplet will process the request and query the db, my db will respond to the droplet and my droplet will forward the data to the user.

Since the droplet and the managed db are in a private network, the total transfer would only be counted against one single time, being the moment my droplet sends the data back to the user, correct?

Thanks

Anyone?:)

That’s correct (at least as I understand it), although technically the initial request coming in would count as well as the response. Just not the traffic between the database and the droplet.
