Enable DNS Resolution from an On-Premises Informatica Domain

Enable DNS Resolution from an On-Premises Informatica Domain

If the Informatica domain is installed on-premises, you must enable DNS resolution over the VPN that connects the domain and the cloud platform.
You can enable DNS resolution on Amazon AWS or Microsoft Azure.

Amazon AWS

To run mappings from an on-premises deployment of Data Engineering Integration to a cluster on AWS, you must install and configure Unbound on an EC2 instance. Unbound enables DNS resolution from an on-premises network. To read how to install and configure Unbound in the AWS VPC, see the AWS documentation.

Microsoft Azure

To run mappings from an on-premises deployment of Data Engineering Integration to a cluster on Azure, you must use the Bind utility on the Azure virtural network.
Follow the steps in the Microsoft Azure article "DNS Configuration."
The article gives an example of the contents of the
/etc/bind/named.conf.options
file. You can put a list of available IP addresses on the domain network in the goodclients portion of the file. The following excerpt shows an example:
//Add the IP range of the joined network to this list acl goodclients { 1.2.3.0/24; # IP address range of the virtual network 1.2.4.0/24; 1.2.5.0/24; 1.2.6.0/24; 1.2.3.253; 1.2.3.254; localhost; localnets; };
