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.
The Many Faces of The Ghostwriting Professional (ghostwriting) Ghostwriting may seem distasteful to some writers, but it is the preferred profession for many writers. Some writers are more satisfied with the act of writing than have their name known by consumers. A ghostwriter is a writer who is paid to write books, articles, stories, and reports that are credited to another person. Ghostwriters have been used by many professionals, including celebrities, executives, and political leader. The writers are usually hired to draft or edit autobiographies, magazine articles, speeches, and other material. The ghostwriter is not always left out; they may sometimes be acknowledged by the author or publisher for assisting in creating the finished product. Ghostwriters have a very important role in the world, and there are many different types of ghostwriters, including nonfiction, fiction, political, medical, blog, and academic writers. Ghostwriters provide an important service to many of their clients. Some people hire ghostwriters to polish and edit a rough draft of their articles and books. If a ghostwriter is used to edit a book or article, most of the language in the finished product will be that of the credited author. Although, some books and articles could not be finished with the help provided by ghostwriting. Typically, ghostwriters are hired to write most of the work, using concepts and stories provided by the author who receives credit. A writer, who writes most or all of the work, will do extensive research on the client or their area of expertise. Ghostwriters always prepare a book or article with input from their client, and the credited authors may provide a basic framework of ideas at the outset, or may provide comments on the final draft of a project. Autobiographies are a common project offered to writers in the field of ghostwriting. When writing an autobiography, ghostwriters typically interview the client, their colleagues, their friends and family, and may also find interviews, articles and video footage relating to the client they are writing for. Ghostwriting may be needed for several reasons and may be needed by many types of people. In most cases, a ghostwriter is needed for a celebrity or public figure who does not have the time, discipline, or writing skills required to write and research an autobiography or other types of books. Publishers to increase the number of books that can be published each year by a well-known author may also recruit the writers. There are many types of ghostwriters, including the nonfiction ghostwriter. In ghostwriting, the nonfiction writer is used by celebrities and public figures that want autobiographies or memoirs published. Nonfiction ghostwriters may also be used to write “how-to” books, or used to write books for professionals in a certain field. Fiction ghostwriters are another type of ghostwriter, which are usually employed by fiction publishers. Political ghostwriters provide their ghostwriting services to public officials and politicians. These political figures employ ghostwriters to respond to the large volume of correspondence they receive. The writers typically draft response letters for the correspondence that is received. Medical ghostwriters are often hired by pharmaceutical companies to produce papers in medical and scientific journals on the outcomes of medications. Some physicians and scientists from academia may also be paid for the use of their name, which enhances credibility of the study. Many professionals have criticized the use of medical ghostwriting, but it is a common practice that seems to have no decrease in action. A web log or blog ghostwriter is one of the newest types of ghostwriters. Many blog operators use ghostwriters to help generate interest in their blog site. These ghostwriters are hired to post comments to their blog, while posing as others by using pseudonyms. This practice is used to generate more traffic and encourage more real posts. Academic ghostwriters are often used by university and college students, and are hired through essay mills to write entrance essays, term paper, and theses and dissertations. Ghostwriting is not desirable for many writers, but ghostwriters seem to provide a much needed service to the writing community.
