How would you load balance http requests? Any manuals?
Have you tried that http://library.linode.com/linux-ha/highly-available-load-balancer-ubuntu-10.04 ? I think with this setup only one node is active at a time, isn't it? |

I am aware of linode node balancers, but I see it as a black box, maybe I am wrong.
I was thinking about nginx, apache load balancers....
What do you think? |

Node balancers are easier, I've used them, you basically push a few buttons and poof! You're up and running.
If you want to do it yourself then a Linode 512 running Nginx using the proxy and upstream modules works well (I've done that too). It's the same cost as a node balancer but you have to keep everything up to date yourself.
Node balancers are more cost effective in a time = money world. |

| And how can you monitor the node balancer? |

| Monitor it for what? It monitors your back ends for you using checks you specify (either http or tcp), the balancer itself linode monitor so you don't have to. |

It's the same cost, and if you only have one 512 without an HA configuration, it's also less reliable. You need more than one node to achieve the reliability of a NodeBalancer, making a NB far cheaper if you care about that. |
