Verify Prerequisites

Verify the following cloud platform and domain prerequisites.

Cloud Platform Prerequisites

Verify the following prerequisites for the cloud platform:

•Create a user account with administrator permissions on the cloud platform.
•Create a resource on the cloud platform where you can create clusters.

- On AWS, create a Virtual Private Cloud (VPC)
- On Azure, create a Virtual Network (vnet)

The Informatica domain and the cluster the workflow creates must be located on this resource.

•If the Informatica domain is installed on-premises, enable DNS resolution.

Domain Prerequisites

Verify the following prerequisites for the Informatica domain:

•An Informatica domain must be installed. The domain can reside on an instance on the Amazon or Microsoft Azure cloud platform, or on an on-premises machine. If the Informatica instance is installed on-premises, you must configure the VPN to connect to the AWS VPC or Azure vnet where the cluster runs.
•You must have permissions to create connections on the domain.
•To create clusters on AWS, the AWS administrator must open the required ports for the security group to use in the VPC where you want to create the cluster.

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 Big Data Management 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 Big Data Management 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;
};
