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.
What is copyright infringement What Is Copyright Infringement? The Layperson's Copyright Primer Copyright laws are constantly changing, and knowing exactly what copyright infringement is, whether you’re creating an eBook, publishing articles, using music as a backtrack to your podcast - or what have you - is essential to selling your online media. Although the laws change from one jurisdiction to another, knowing the basic rules of copyright infringement will ensure you’re following the proper rules of engagement when it comes to creating your works. Before you make any final decisions regarding the use of a work that has been copyrighted, please contact a copyright attorney to ensure you’re following the law – this will keep you from being sued or, even worse, punished in a court of law. What is Copyright Infringement? Copyright infringement, as defined by Wikipedia.org, states: “Copyright infringement (or copyright violation) is the unauthorized use of material that is protected by intellectual property rights law particularly the copyright in a manner that violates one of the original copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works that build upon it. The slang term bootleg (derived from the use of the shank of a boot for the purposes of smuggling) is often used to describe illicitly copied material.” So, what is copyright infringement in plain English? It means that if you’re not allowed to use something, then don’t use it – plain and simple. It can be very simple to get permission to use a work – many times you’ll be able to use a ‘sample’ of music or excerpt of written work for a nominal fee, or small attribution. However, if you do not have the permission of the copyright holder – whether it’s an author or a publishing house – you can be sued for copyright infringement or worse. What is Copyright Infringement in America? In many jurisdictions, such as the United States of America, this act is known as a strict liability crime or tort (a tort is a civil wrong – not a criminal wrong). This means that the person who infringes the copyright - whether intentionally or not - will be responsible for the damage or loss. Also, the prosecutor (in criminal court) or plaintiff (in civil court) must only prove that the act of copying was committed by the defendant – they do not need to prove guilty intent. This means, even if you had no intention of committing copyright fraud or infringement, you can (and in present times, in many cases, WILL) be prosecuted, even if you used the material in good faith. What is Copyright Infringement in action? Many cases of copyright infringement are difficult to see to the layperson, because the violation is not limited to exact copying. In many cases, when something is inspired by another thing – such as in music, when the inspiration of one song is used to create an entirely different song – it’s difficult to see where the new product or ‘thing’ has crossed the line to something illegal. Some works aren’t even protected by copyright, such as compilation of facts that lack the creativity necessary to be covered by copyright, or works that are in the public domain because the copyright has expired. Knowing the difference is often very difficult to see, and because of this we’ve seen a number of copyright infringement cases in recent years, especially in tandem with the music industry. As you can see, copyright infringement is a very difficult, albeit necessary, act to define. However, if you make sure that you’re using works that are in the public domain, or have long since been out of copyright (think Beethoven or Frankenstein) you’ll be safe. Do you fair research, and if you have any questions contact a copyright lawyer and ask ‘what is copyright infringement’ to learn the most up-to-date information for your jurisdiction. Copyright Music Form The Copyright Music Form is your First Step to Protecting your Work Many confuse a copyright music form with an actual copyright. The form is actually what you get from the U. S. Copyright Office when you are ready to register your copyright. It is highly recommended that everyone who writes a piece of music take the time and register their copyright. It is also important to understand that once you've either written or recorded your original music, it is actually copyrighted. In other words you do not actually need to fill out any type of copyright music form in order to have your music copyrighted. While registering is not the act of copyrighting your work it is very necessary if you plan to file suit for copyright infringement. It is also better to fill out the copyright music form they offer earlier in the life of your music rather than later as the timing of the registration of your copyright can have an impact on the actual awards you can receive should you win your lawsuit. There is also something quite satisfying about having your musical works registered with the copyright office. I can't explain the feeling as it will be different for everyone but if you've written music, you really should see for yourself. You can find the copyright music form from the U. S. Copyright Office online quite easily. There is more involved than simply filling out the paperwork in order to register your copyright. You must also pay a fee, the actual fee changes so you should make sure you are aware of what the current fee is before sending in your work. An insufficient fee can result in delays. You also must send an actual copy of the music you are registering the copyright on. Your copy may either be the written or recorded music you wish to register but must include everything you wish the registration to cover. When filling out the copyright music form it is important to provide as many accurate details as possible. While your registration is active the day your application is received you may not actually receive your certificate for several months. Really and truly, as far as government agencies go, this is one of the easier ones to deal with as far as red tape. The procedure in addition to the copyright music form is straight forward and not designed in a manner that would be too easily confusing. The copyright music form is only one step in the process of registering your music's copyright. While it is an important step if you forget the other steps there will be delays in the registration process. Read the form completely before filling it out and if you are printing your form from the computer, I highly recommend printing more than one copyright music form to insure that you have extras if you make a mistake and in order to register your future musical copyrights. Your first copyright registration will be the most nerve wracking. This makes perfect sense when you consider that trying anything new requires some degree of 'anticipation'. It is also likely to be your most thrilling. Even in this particular piece of music ends up being the worst piece you've ever written (most of our first endeavors are our worst) there is a lot to be said about the fact that you've actually taken the steps to insure your future is a great feeling. If your first piece of music sells and is someday published that is wonderful. If not, you are still ready for the next piece and have gone through the process of filling out a music copyright form before so you know what to expect. |
