LemonLDAP::NG est hautement scalable, donc facile à insérer derière un répartisseur de charge :
|
|
</p>
|
|
<ul>
|
|
<li class="level1"><div class="li"> Le portail ne stocke aucune donnée en dehors de la base de données des sessions, ainsi on peut avoir plusieurs serveurs utilisant le même nom d'hôte HTTP</div>
|
|
</li>
|
|
<li class="level1"><div class="li"> Tous les agents téléchargent intégralement la configuration, donc plusieurs serveurs peuvent servir le même hôte virtuel</div>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>
|
|
Par exemple on peut créer un cluster avec <a href="http://www.linux-ha.org/wiki/Heartbeat" class="urlextern" title="http://www.linux-ha.org/wiki/Heartbeat" rel="nofollow">Heartbeat</a> et <a href="http://haproxy.1wt.eu/" class="urlextern" title="http://haproxy.1wt.eu/" rel="nofollow">HAproxy</a> :

|
|
</p>
|
|
|
|
<p>
|

Il faut juste partager les bases de données de configuration et des sessions entre ces serveurs :
