plexus2 Server Packs

plexus2 can be used to power web sites and/or databases for Internet (World Wide Web, or external) sites and intranet (internal) sites.

If you need to power an intranet site, or deliver information from your own servers, your best option is to purchase a plexus2 Server Pack and host it yourself. If you have more typical web site requirements, and don't need to operate your own server, you may prefer to purchase a plexus2 Hosting Pack. Further information on plexus2 Hosting Packs can be found under Purchase Options.
