Setting up a Teracloud® Streams basic domain on a single resource

A basic domain has a single Teracloud® Streams resource and user. This type of domain is typically used for test or development environments.

Teracloud® Streams uses the Pluggable Authentication Module (PAM) authentication service for user authentication, and Apache ZooKeeper for managing and storing configuration information. By default, Teracloud® Streams uses an embedded version of ZooKeeper, which is included in the product installation.
