A cloud computing process is one which staggers multiple networks sometime and mainly unknown to the webmaster into a network or cloud of data. In this example it is IP and Netaddy names to control access lists.
This will prevent predators from exposing your network to lag and other attacks from link farming, often this means many xoops are attacked in occasions which is all the time caught by protector, this way if an attack is in process across a large spectrum of links, your site will down itself to your sourced attack even if it is discovered on a completely unaffiliated site that is link farmed to yours or on a XOOPS User list.
Xortify is a cloud solution to protectors Bad IPs, if someone attempts to hack your site and becomes a bad IP it will then send the IP to the Ban Cloud on Xortify.com and its paired cloud Xortify.chronolabs.coop. It will also poll the server to make sure it has the latest ban list so your website will be aware of malusers before they attack through farming IP from services like Google or bing.
Xortify with the IP Cache has had a dramatic improvement of performance, it only now polls an individual once maybe twice by default every 24 hours, you can adjust this by changing the IP Cache Time.
