To connect to an AWS instance, configure instances and software for your scenario.
| Use Case | Configuration |
|---|---|
| EC2 instances used within the AWS public cloud |
|
| EC2 instances used to connect from the AWS public cloud to an on-premises Teradata system | Configure the software using public IP addresses to connect to the on-premises Teradata system. |
| Before deploying an instance using a public VLAN |
|
| Before deploying an instance using a private VLAN |
|
Instance location determines whether to use internal (private) or external (public) addresses when configuring the following software:
- Teradata Data Mover
- Teradata Query Service
- Teradata Viewpoint
For example, use Vantage private IP addresses in Data Mover job XML and Data Mover portlets if all AWS instances reside in the same VPC. In Data Mover portlets, use the private IP address of the Data Mover instance to connect to a Vantage system. If source and target systems reside outside AWS, such as an on-premises system, use the public IP addresses instead.
Only the software listed previously can connect to an on-premises system if you opened the appropriate inbound ports in the corporate firewall at those locations.
