Scale Out with Load Balancer (adding a node)
I am searching whole the day, but found nearly nothing.
I need a load balancer with the option to balance some nodes, like apache or nginx can do. But at a specific threshold (i.e. 100 connection), the load balancer should use another node/ip. (im my case: an elastic ip from amazon ec2).
I cannot find a configuration option in nginx or apache mod_proxy.
I am not forced to use one of these two. If you have other, please feel free to mention. :-)
It would be great if someone has an idea for this issue.
