==== Functionnal architecture of Rudder

|
||
Rudder contains several functionnaly independant components, illustrated in the diagram below:
|
||
|
||
* Inventory database
|
||
* Configuration policies database
|
||
* Compliance database
|
||
* Event logs database
|
||
* User interface: Web and REST API
|
||
* Node interface: inventory reception, state reports reception, configuration policy sharing
|
||
* Relay server to centralize networks flows of an isolated network zone
|

||
==== Network architecture in client/server mode
|
||
|
||
The Rudder server listens for incoming connections from the agents installed on the nodes to manage,
|
||
and communicates with them. The connection frequency from nodes to server is configurable, from several
|
||
minutes to several hours.
|
||
|
||
The following schema shows the network architecture of a Rudder installation:

|
||
|
||
You can see that relay server allow separating some network areas (for example a DMZ,
|
||
a specific datacenter or remote site) using a local server for each area to distribute
|
||
configuration policies and centralize agent reports and inventories.
|
||
|
||
==== Agents
|
||
|
||
TODO
|
||
Agents can be installed using a simple software package (`.exe`, `.deb` or `.rpm`).
|
||
|
||
The agent has a very small memory footprint (< 20MB), and is very fast applying configurations
|
||
(complete runtime below 10 seconds for hundreds of configuration components).
|
||
It requires at most 500MB of free disk space.
|
||
|
||
Rudder is currently supported on all major Linux distributions (Red Hat Enterprise Linux and derivatives
|
||
like CentOS and Scientific Linux, Debian, Ubuntu, SUSE Linux Enterprise, etc.) for all supported versions,
|
||
but also for older unsupported ones, Windows for desktops and servers (Server 2008 R2 or newer),
|
||
AIX (5.3 or newer). Experimental builds for Selorais, FreeBSD, Android and Mac OS X alsoe xist,
|
||
as well as a version for ARM architecture.
