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.
Making Effective Web Publishing Content (web publishing content) Web publishing content is important for a successful website. The content of a web site can often make or break that site, and it is important to make the site as attractive as possible, without over doing it. The content of a web site must be updated on a regular basis to keep web surfers coming back. Updated web content not only keep surfers coming back, but is also indexed more frequently by search engines. Fresh material is one of the key aspects of successful web publishing content and may generate fresh faces to a web site. One way to update the content of a web site is to update the existing web pages. Providing new content could include updating the conditions of a service, adding a new product or service, or creating a turnkey solution that will save the customer’s money or time. The web content should reflect the most recent information about a business. It is simple to provide changes to the web content, but many web sites provide updates without providing a notice. So, it is indicative to provide a notice of change each time web publishing content is changed. The announcements should be displayed prominently on the web site so that all surfers are able to see. It is also important to write articles for the web site. Articles can be seen as a valuable source for a web site’s success. The articles can be used to educate visitors on the web site and the business, while showcasing the owner’s expertise. Articles can be posted on the web site or used in a newsletter and submitted to other newsletters and web sites for syndication. This web publishing content can be used by other web site owners, which will provide leverage to the articles while generating publicity for the author and the author’s web site, while exposing them to new audiences. Writing an article seems simple enough, but there are many web site owners who are unable to find topics to write on. However, topics may be more evident than most web content writers may think. Topics for articles can be found in the news, in conversations with clients and colleagues, in networking events that are attended, and even in speeches. Blogging is also an excellent way to expand your list of web publishing content. Most web site owners can benefit from learning to blog, learning to start a blog, learning how to gain readers, and learning to make money from blogs. Blogging is becoming one of the most popular tools for showing new content on a web site. A web log can be used to answer web site visitors’ questions, inform users about new services and products, and to keep them up-to-date on industry news. Blogs are a great resource for sharing opinions and displaying expertise. The blog can be used to help an owner connect with their web site visitors while generating new web site content. Updating web publishing content on a regular basis is vital to the success of a web site and very important for many web site owners. Articles, newsletter, and blogging should be a part of a regular business schedule, and will work perfectly in keeping a web site owner connected to their visitors. The quality of the web content on a web site can make it more attractive to users or can make it very unattractive to users. Owners should use their expertise to provide writing that is interesting and necessary. Visitors will appreciate the extra effort and owners will get the rewards of maintaining good web content for their users. The Makings of a Magazine: Do They Include You? (writing magazine articles) Magazines are everywhere. They are published on nearly every subject you can imagine, in duplicate and triplicate and more. All that a start-up magazine needs is a niche and an audience. While there may be hundreds of cooking magazines out there, a new one could come up if it should cover cooking for your pets. In fact, there may already be such a magazine in existence. The niche is cooking for pets. The audience is those people who want the healthiest foods for their pets and are willing to put the time and effort into making it for them. If you are interested in writing magazine articles, you’ll be sure to find one that is perfectly suited to your interests and abilities as a writer. Because there are so many magazines, it won’t be difficult to find one that you will enjoy becoming a part of. What You Should Know Magazines survive on advertising. The advertisers pay because the content is good enough that readers will invest in the glossy covers again and again. The best way to find a healthy magazine is to look through the racks for thick publications. They will only be full of content if they are full of advertisements. The big magazines can afford to pay their writers more, but they can also afford to pay only the best writers. Even though there is quite a lot of space to fill with content, you may have a hard time getting published in major magazines at first. Smaller magazines do not have quite the readership and so they also do not have quite the advertisement content. The space will be limited and the pay will be lower, but these magazines will be more open to new writing talent nonetheless. The More You Know, the Better When it comes to a writing career, the more you know the better off you will be. It is not hard to figure out that you will have the best chances for publication if you can write on a variety of topics. You should not limit yourself to a small area of expertise. Work to become an expert in every topic you come across. There is no possible way of course to be an expert in every area of human knowledge, but it will help you in writing magazine articles to learn every new piece of information that you can. For example, if you were to send a query to a health and fitness magazine about writing a short piece about general mountain biking tips they may accept it. They may also then request additional information about the pros and cons of using a road bike on mountain trails. If you only know about mountain bikes, you’ll be stuck. If you have worked on broadening your horizons though, you’ll be able to produce the work that the magazine editor requires. Getting On Staff Querying magazines is a way to get published, but if you need a more stable job, you may be interested in getting on staff with a magazine. Writing magazine articles is a talent. If you can consistently bring an editor what he is looking for, you might have a chance. To improve your chances, in addition to writing effectively, it will help to have some significant education behind you. If you are serious about making it to the masthead of your favorite magazine, it’s time to go to school. A degree will help your credibility as a writer and will help you open doors into the magazine publication world. Writing magazine articles takes a special kind of writer. You have to have a feel for what people are interested in reading about. The magazine content will help you understand how to write for a particular magazine and audience. You can also improve your chances of writing accepted articles by improving your knowledge base. Don’t be picky about what you’re willing to learn and you could go very far in the writing business. |
