Bring Your Own License

The optional bring your own license (BYOL) feature allows you to use a license purchased directly from Teradata in the public cloud. See Obtaining Teradata Licensing Information for BYOL. You can bring your own license for the following products:
  • Teradata Database (Base, Advanced, or Enterprise license tier only)
  • Teradata IntelliSphere

The quantity of licenses is expressed in TCores, for which the value is based on the instance type and I/O capacity. Adding more nodes increases the required number of TCores. Fewer TCores means fewer virtual CPUs. More TCores allow you to deploy more virtual CPUs. In this way, the quantity of TCores affects the performance capabilities of the system.

TCores can be activated, revoked, and redeployed on public cloud platforms where Teradata Database is offered. They are portable between public cloud platforms. If you want your TCores to be portable between a public cloud platform and Teradata IntelliCloud or an on-premises systems, contact your Teradata Account Team.

An entitlement provides you the right to use Teradata software. The Teradata EMS server ( enables you to view and manage your entitlements. See the Teradata Entitlement Management System (EMS) Customer User Guide. When launching a Teradata ecosystem or Teradata Database using CloudFormation, each Teradata Database instance automatically requests a license activation from the Teradata EMS server. If additional TCores are needed to properly license the software, contact your Teradata Account Team.

To use BYOL, you must first subscribe to the software on AWS, then launch Teradata Database, with or without a Teradata Database ecosystem. After launching Teradata Database, you can launch additional Teradata software products separately if desired. See Subscribing to Teradata Software.

BYOL requires the following:
  • Internet access while the instance is running.
  • VPC with access to the AWS endpoints.
  • Port 443 is open to access the Teradata EMS server. See Security Groups and Ports.
  • For inbound and outbound ports, open a protocol for All only for internal communication between the instances (not external). See Security Groups and Ports.

To renew a license, contact your Teradata Account Team.

After a license expires, warnings are sent to the AWS CloudWatch logs (look for log group Teradata/DBS/stack-name and log stream telm_stack-name). The warnings are followed by periodic database restarts and eventually the database is disabled.
