Specifically, Conga provides:

A single web interface for all cluster and storage management tasks

Automated deployment of cluster data and supporting packages

Easy integration with existing clusters

Integration of cluster status and logs

Fine-grained control over user permissions

We’ll take a look at each of these features as we walk through some basic Conga tasks later in this article. To start, let’s take a look at just how Conga works.

Architecture overview: When Luci met Ricci

The following diagram illustrates the Conga architecture.

Fig.1. The Conga architecture.

The elements of this architecture are:

luci is an application server which serves as a central point for managing mulitple clusters.. luci maintains a database of node and user information. Once a system running ricci authenticates with a luci server, it will never have to re-authenticate unless the certificate used is revoked. You’ll typically have only one luci server for your clusters.

ricci is an agent that is installed on all servers being managed.

the web client is typically a browser, like Firefox, running on a machine in your network.

The interaction is as follows. Your web client securely logs into the luci server. Using the web interface, the administrator issues commands which are then forwarded to the ricci agents on the nodes being managed.
