Server Management Options
Teradata Database supports multiple instances of Teradata Server Management in the public cloud. Multiple instances (CMICs) provide high availability and management of larger database systems. High availability requires at least two CMICs, each of which can manage up to 70 nodes.
You can deploy Teradata Server Management using CloudFormation, either as part of a Teradata Database ecosystem or separately. Both options offer the ability to select multiple CMICs.
