Gates and Guard Dogs: Safeguarding Your Data the Right Way

We talked earlier about the importance of redundancy. Naturally, an equally critical concern is security, both of the data itself and the servers that host it. After all, if you choose the wrong web hosting provider, your e-commerce site might end up stored in their basement or garage.

Host Duplex spares no expense when it comes to protection. Steadfast's Chicago data center houses the majority of our servers in the Equinix building, renowned throughout the industry as a fortress to be reckoned with. (Just getting into the building requires a background check, for starters.) There, each server has two power supplies, each with its own feed, battery backup, and diesel generator capable of running each machine for hours. Beyond even that, Steadfast has a contract with a local fuel provider to bring in extra diesel fuel immediately should any major outage ever occur. Not to be outdone, we have our own large stock of parts stored at our facility, ready to remedy any hardware issues at a moment's notice.

On the software side of the occasion, our automated monitoring system keeps a constant watch for exploits, vulnerabilities, and any suspicious behavior, keeping our live staff alert around the clock. Our management service, should a client choose to make use of it, also installs and configures the client's firewalls, while at the same time optimizing server performance, running updates, and performing weekly checks across all systems. (Clients always have the option of installing and configuring their own firewalls, of course.)

Together with some of the industry's brightest minds and strongest facilities, Host Duplex ensures that your data is as safe and rock-solid as it possibly can be.

What is Redundancy and Why is it Important?

In the world of web hosting, there's plenty of terms that get used without companies providing adequate definitions.  I wanted to take some time and share a few words with you about Redundancy.

Redundancy is in layman's terms backup.  There are also several different types of redundancy: Network, Hardware, Power, and Geographic. A solid web hosting company will have multiple layers of Redundancy to ensure that your data is safe and to maximize your uptime.

Network Redundancy:

This backup is simply for the network a web hosting company uses to get you online.  Reliable proviers have multiple internet carriers that their servers use to ensure that your website never goes down.

Hardware Redundancy:

This backup is for the physical pieces of server hardware.   For instance one layer of redundancy is for the hard drives.  Here at Host Duplex, if a hard drive fails in our Dell PowerEdge servers, your site will not go offline, we have hot spares in place so our RAID arrays are immediately rebuilt.  We have a similar system for our sticks of RAM.

Power Redundancy:

These are the backups for the power that keeps your servers and data center running.  All of our servers have redundant power supply units.  Each PSU has a feed from a different utility company.  Each feed is also connected to it's own UPS (uninterrupted power supply) which hold 3 hours of battery backup should the data center lose power, which is also connected to diesel generators should a power outage last longer than 3 hours.  So if an entire feed fails, including the feed's UPS and generator, there is still a second feed from a separate electric provider with its own UPS and generator to keep your site online.

Geographic Redundancy

Finally there is geographic redundancy.  Host Duplex provides geographic redundancy services so that in the case of a complete datacenter failure, your site can be rerouted to a different datacenter.  I'm proud to say our data center is protected like Fort Knox and has enough redundancy to remain operational through natural disasters.  However, should the apocalypse take down our data center, Host Duplex offers services to have your site working non-stop in our Denver datacenter.

Hopefully this clears up any confusion or questions regarding Redundancy.  If you have further questions, feel free to comment, or shoot us an email directly.
