Deploying Teradata Server Management
Teradata Database supports multiple instances of Teradata Server Management (CMICs) in the public cloud to 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.
When you deploy multiple CMICs using AWS CloudFormation, the CMICs are automatically configured to communicate with each other. However, the newly deployed CMICs must be configured manually to manage the existing database and application nodes in the Teradata ecosystem.
