Forum OpenACS Q&A: Re: How to use/configure Host Node Map

Thank you, Richard. I agree.

Both virtual hosting and host node mapping are important tools in optimizing the greening of operations using OpenACS (which is green to begin with) in that they conserve resources.

Running a reverse proxy in front of a bunch of aolserver instances has worked well for us over the years, but tends to use a little more RAM than other systems. Better performance is to be expected at the cost of more RAM when RAM/storage/processing usage are tracked. Still, we think virtual hosting and host node mapping will provide a way to get the improved performance of OpenACS without any significant offset, ie measurable cost savings.

The separate databases and shared database pools of virtual hosting is optimal for small sites with multiple clients.

Host node mapping seems to be an optimal alternate for sites operated by a single organization that wants to consolidate resources further, and offer a single user account shared between sites.

I want to help make virtual hosting a configuration option of Openacs, once host node mapping is tamed.

cheers,

Torben
