LemonLDAP::NG is highly scalable, so easy to insert behind a
|
|
load-balancer:
|
|
|
|
- Portal does not store any data outside the session database, so you
|
|
can have many portal servers using the same HTTP host name
|
|
- All handlers download the whole configuration, so many servers can
|
|
serve the same virtual hosts
|
|
|
|
You can for example set up a fail-over cluster with
|
|
`Heartbeat <http://www.linux-ha.org/wiki/Heartbeat>`__ and
|
|
`HAproxy <http://haproxy.1wt.eu/>`__, like this:

|
You just have to share configuration and sessions databases between
|
|
those servers:
