Running with VPC peering


#1

Has anybody successfully accessed Datomic Cloud across peered VPCs? Our app uses another service that requires VPC peering, and the same procedures do not work when applied to Datomic.


#2

What specific issue(s) are you encountering?

As documented here, you can indeed use VPC peering to connect to a Datomic Cloud instance from another VPC.

There are several bi-directional configurations required. In particular, did you configure the route tables and the security groups in both the Datomic Cloud VPC and your VPC to enable mutual access?


#3

I pretty much followed the instructions as stated, configured datomic-$(SystemName)-entry to allow entry from my app security group. Since it did not specifically say to do the reverse and I had recently been able to configure VPC peering with a managed Kafka service without this step, I did not try that. We are curently running successfully in the Datomic apps SG provided by the install. I will try the bidirectional config on our next iteration of ops configuration.
