Datomic runs in a private VPC. To allow access from outside the Datomic VPC
(e.g. for developers), you must add an inbound rule to the
access gateway security group.
NOTE Access gateway instances are secured by a
keypair that is accessible to Datomic administrators. If you want to
further restrict access by IP also, you can enter a specific IP address or range
of addresses for Source in the instructions below.
