Hi Athanasios,

I guess you are asking for the lb module in the puppet. Then that lb module
in the puppet will install the Stratos load balancer[1].

Also we have extensions for the HAProxy[2] as well as nginx[3].Those load
balancer extensions can work as a Standalone applications.Please refer the
related documents.
Also we have a sample[4] for use the Stratos LB with tomcat application.I
guess you can do the same thing with nodejs also.
Hope those documentations will helpful for you
