In traditional web hosting, every piece of technology stands alone: sites live on a single hard drive, inside a single server, connected to the Internet through a single network connection. It's a simple setup with one big problem: if any part fails (say the server crashes or the hard drive dies) the whole system goes down, and all the websites suddenly stop responding. Ouch. That can make clients pretty angry.
Look Impressive? It is:

Technologists would say that common hosting setups are riddled with Single Points of Failure or (SPFs). One failure anywhere can wreak havoc on the entire system. Until recently, it's only been large companies like Amazon.com or Yahoo that have had the resources to develop more stable solutions.

Now, for the first time, Clickable Hosting (powered by Mosso/Rackspace) brings Enterprise-level technologies to web developers and designers everywhere.

To tackle the problems above, we use a radically different approach to hosting, a truly enterprise-level architecture designed from the ground up to be reliable, redundant, and secure. Our proprietary technology deploys each website across entire clusters of servers, all working intelligently together, all poised and ready to instantly reroute web traffic should any component experience failure. That means when a server crashes or a hard drive fails, the other servers in the cluster pick up the slack without a moment of downtime or a byte of lost data.
It All Starts With Storage

Nothing as important as your website should be served from a single hard drive, but you'd be surprised by how many web hosts have little more redundancy than a pair of crossed fingers. We're different--and for good reason. The advanced architecture powering our hosting solution uses groups of high-performance, network attached storage devices to reliably serve every web page, image, and email. Inside each storage device, drives are mirrored to each other in a RAID configuration to create a first level of redundancy. Then, advanced software clusters the storage devices into logical groups, where files are instantly and automatically replicated across each device. And, as a final precautionary measure, all data on the system is automatically backed up continuously.

Cluster Structure

With your content stored securely, the next task is to make sure it's available each and every time it's requested. This is another area where we've taken a decidedly different approach to hosting. Most hosting companies ask, "How can we fit the most websites onto each server?" Sharing a server means an errant script used on a neighboring site can bring your site down as collateral damage. So we decided to turn the question around, asking, "How can we have the most servers respond for each website?"

It took two years and over a million dollars to answer that question, but the results are impressive. Advanced clustering technology routes each site request to not just one server, but through an army of load balanced IIS and Apache webservers. Should any server in the cluster not respond, requests are instantly and intelligently routed to the remaining servers, and the website visitor never experiences a single interruption. Contrast that to the more common approach, where a server crash simply means visitors are turned away until a technician has resolved the problem.

Special Agents

The clusters that power our hosting solution are specialized, too; each one designed and optimized to do a specific task, and to do it extremely well. Once again, intelligent routing software analyzes each request, and sends it to a server cluster that performs the task without emulation and without compromise.

Every piece of your web software, from Microsoft technologies like .Net and MS SQL, to popular open source technologies like PHP, can take advantage of the speed and reliability of an optimized, native environment, built through partnership with the actual companies that develop the software.
