Web Hosting - Redundancy and Failover
Among the more useful innovations in computing, actually invented decades ago, are the twin ideas of redundancy and failover. These fancy words name very common sense concepts. When one computer (or part) fails, switch to another. Doing that seamlessly and quickly versus slowly with disruption defines one difference between good hosting and bad.
Network redundancy is the most widely used example. The Internet is just that, an inter-connected set of networks. Between and within networks are paths that make possible page requests, file transfers and data movement from one spot (called a 'node') to the next. If you have two or more paths between a user's computer and the server, one becoming unavailable is not much of a problem. Closing one street is not so bad, if you can drive down another just as easily.
Of course, there's the catch: 'just as easily'. When one path fails, the total load (the amount of data requested and by how many within what time frame) doesn't change. Now the same number of 'cars' are using fewer 'roads'. That can lead to traffic jams.
A very different, but related, phenomenon occurs when there suddenly become more 'cars', as happens in a massively widespread virus attack, for example. Then, a large number of useless and destructive programs are running around flooding the network. Making the situation worse, at a certain point, parts of the networks may shut down to prevent further spread, producing more 'cars' on now-fewer 'roads'.
A related form of redundancy and failover can be carried out with servers, which are in essence the 'end-nodes' of a network path.
Servers can fail because of a hard drive failure, motherboard overheating, memory malfunction, operating system bug, web server software overload or any of a hundred other causes. Whatever the cause, when two or more servers are configured so that another can take up the slack from one that's failed, that is redundancy.
That is more difficult to achieve than network redundancy, but it is still very common. Not as common as it should be, since many times a failed server is just re-booted or replaced or repaired with another piece of hardware. But, more sophisticated web hosting companies will have such redundancy in place.
And that's one lesson for anyone considering which web hosting company may offer superior service over another (similarly priced) company. Look at which company can offer competent assistance when things fail, as they always do sooner or later.
One company may have a habit of simply re-booting. Others may have redundant disk arrays. Hardware containing multiple disk drives to which the server has access allows for one or more drives to fail without bringing the system down. The failed drive is replaced and no one but the administrator is even aware there was a problem.
Still other companies may have still more sophisticated systems in place. Failover servers that take up the load of a crashed computer, without the end-user seeing anything are possible. In fact, in better installations, they're the norm. When they're in place, the user has at most only to refresh his or her browser and, bingo, everything is fine.
The more a web site owner knows about redundancy and failover, the better he or she can understand why things go wrong, and what options are available when they do. That knowledge can lead to better choices for a better web site experience.

Copyright infringement insurance coverage Do You Need Copyright Infringement Insurance Coverage? People are creating more content now than ever: eBooks, blogs, web journals, MySpace Pages, Podcasts. Every where, in abundance, you’ll find people sharing their ideas and opinions, and creating entertainment for everyone. However, with all the resources available to us, how can we be sure that we’re not violating copyright law? Should we have copyright infringement insurance coverage? Copyright infringement is the act of using someone else’s copyrighted material – in any form – in our own use without proper allowances. In order to be allowed to use the material, all we may need to do is ask and give the owner royalties, attribution, or some combination thereof. But, occasionally, it’s easy to forget that we need to ask before we use something without rights. You’re allowed to use copyrighted works in a number of forms – educational and instructional uses, parody, commentary, and news are all forms where you don’t need to ask for use – it’s considered fair use under the copyright law. However, even if you’re using the item of copyright in one of these forms, it would still be wise to inform the owner of your intent before using it. Of course, you should contact a copyright lawyer before using anyone else’s work(s), but to keep yourself safe, copyright infringement insurance coverage may be a good bet for you and your colleagues. Should you have copyright infringement insurance coverage? Although this is a new concept, it is one we should look at closely as creators. A well-known adage “there is no completely original idea” comes into play in our current age – while it’s entirely possible for us to have a thought, and act upon the thought – there may be, somewhere, someone who has created close to the same material as we have, without our knowing. Did we create it first? Did they? Would they be able to sue you for copyright infringement? These are the things to ponder as we create our media – should we have copyright infringement insurance coverage? What is copyright infringement insurance coverage? This coverage would be insurance for covering the cost to settle lawsuits brought in regards to copyright infringement – it would be a small amount of coverage. For example, you would only need around $5,000 to cover the court and attorney fees associated with a case, if a suit were brought against a person. Theoretically, you would only pay under $25 per year and would cover up to the five thousand dollar settlement should a case be brought against you. How would you use copyright infringement insurance coverage? Hopefully, you’d never have to use your copyright infringement insurance coverage. But, it would be there in case a charge was ever brought to you on copyright infringement With so many of us – bloggers, columnists, podcasters – creating our own content, it’s in our best interest to consider something such as this. We may not always get the rights we need in order to use a work, either whole or in part. As you can see, it can be critical to have copyright infringement insurance coverage as a blogger, podcaster, columnist, or other content creator. It’s imperative that we know our rights to use something (or to NOT use something) and what we can do to protect yourself. Copyright infringement can carry a serious penalty, and insurance coverage is a good way to insure that you’re protected from hefty fines.
