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.
Writers Block: What Causes it and How to Overcome it (writers block) If you are a writer then you know what I am talking about. You have everything ready, a drink, a snack, the topic, and even reference material. You sit down ready to start typing or writing, which ever you prefer, and it happens. You are stuck, your mind is blank and you have no idea how to fill that blank canvas in front of you. It is a writer’s worse nightmare come true. You have writers block. First you need to figure out what is causing it. There are a multitude of things that can be causing it. Stress is one of the biggest factors that cause writers block. Whether it is stress caused by personal matters, deadline dates, or fearing your article won’t be good enough it can block the words from flowing as easily as the should. Sleep deprivation doesn’t let your mind function to its full potential. Getting a good night’s sleep is imperative to having a clear mind and being able to focus. The project itself could be causing the writers block. A topic you are not interested in can easily turn your normally resourceful mind into jelly. The research on that topic turns into a grueling task. Then trying to put the words on paper that make sense and will peak someone’s interest seem impossible. If a topic has personal meaning to you it can be hard to write objectively about it. A simple informative topic can easily become a personal rant session. Writing because you have to, not because you want to makes it hard to concentrate and focus. Now that the basic causes have been covered, you need to know how to fix it. Writers block is not permanent. Identifying the reason is the hard part. Relax. The world is not going to end if the article isn’t as perfect as you feel it should be. Just because you don’t think it is perfect doesn’t mean someone else won’t. Go and read some of your previous writings. Even if what you read has nothing to do with your current topic, it can be inspirational to you. Don’t burn yourself out on a topic. Try to split up the writing process. Research and brainstorm one day and write the next. This will give you time to think about your topic and figure out the angle you want to write. Talk your way through it. Call a friend or colleague and chat. Tell them the topic you are working on and get their opinions or ideas. They may be able to offer fresh insight and ideas. Work on multiple projects at one time if you can. Bouncing back and forth between a few topics can keep your mind hopping and will keep boredom at bay. Take a break from you current project and write about something that motivates you. Chances are once you get those creative juices flowing they will continue into your next project. Make yourself a schedule and stick to it. If your schedule says 500 words by noon, write your 500 words and stop. Even if you don’t have a project going, by writing daily you will stick to your schedule and keeps your imagination going. If you write from home, which most of freelance writers do, make a quiet time and treat it like a real job. If you have young children at home, write while they nap. Let your answering machine be your secretary. If it is important they will leave a message. Most importantly remember why you started writing in the first place. Even the best of the best have gotten writers block at one time or another. Examine the Interior of Publishing Companies (publishing companies) The publishing company can be seen as the backbone of the writing world. Written words seemingly would not have been able to be seen without publishing companies. The publishing company provides a great service to society by publishing and displaying the work of authors. The existence of publishers is obvious, but the interior of the publishing world and its companies is unknown by many people. Publishing is known as an apprenticeship industry, which means that most of the knowledge needed by a publishing professional will be learned with hands-on experience on the job. Generally, information that is learned in one department of a company is useful throughout the publishing house, which gives professionals the opportunity to move between departments. There are many levels to a publishing company and they all have different functions. The administrative level is the first level of any company, and has many responsibilities in the functioning publishing companies. The administrative department is responsible for managing daily operations for publishing executives and management. This responsibility involves interaction with all of the employees from all of the departments, as well as interaction with authors and agents. The administrative employees are required to manage the calendar, maintain organized files, screen/prioritize mail, draft correspondence, make travel arrangements and prepare itineraries, process expense reports, take minutes at meetings and prepare reports. A position as an administrative employee allows a person to have a high-level of understanding of a publishing company, while being visible to executives. Advertising is another division of publishing companies. Most publishing companies have in-house advertising agencies that purchase media space and create and design advertisements. In a publishing company, the advertising department works closely with the marketing directors, editors, and publishers of titles to create an advertising plan that will promote sales of an individual book. Every advertising plan requires research and negotiation to provide the best venues and the most cost-effective methods of advertisement. These employees also work closely with graphic designers, commercial sales representatives, printing presses, and internal staff to facilitate the run of advertisements. The editorial department of a publishing house is one of the most important departments. This department acquires, negotiates, develops, and edits book projects for publication. The daily activities of editorial employees include preparing acquisitions for transmittal to the production department, developing and maintaining relationships with authors, booksellers, and agents, performing general administrative duties, participating in editorial, design and marketing meetings, and reading and evaluating submissions by writing reader’s reports. The editorial department must work closely with all departments. Another division of publishing companies is the marketing department. The marketing department has the responsibility of creating, preparing, and establishing marketing strategies and policies for each title by coordinating the efforts of the publicity, promotion, advertising, online, and sales departments. The marketing department is responsible for preparing all sales presentation materials, audio recordings, fact sheet collation, and promotions, creating and producing additional account-specific presentation materials, researching and establishing relations with new markets, and planning and maintaining sales and marketing schedules. The publisher’s office is also an important department for many publishing companies. The publishers oversee the life cycle of a title from acquisition to production, and onto the sales force. Publishers are responsible for making executive decisions for all titles within assigned imprints while staying within any cost restraints. This department is also responsible for sponsoring book projects, strategies, and initiatives for the publishing company. The subsidiary rights and permissions department is also one of the most important divisions of a publishing company. This department finds additional sources of profit for a given title, including serials, book clubs, and paperback, audio and e-book rights. The daily activities for the subsidiary department include writing submission letters, sending manuscripts, proposals, and books to foreign publishers and agents, coordinating co-productions with other publishers, working with book clubs and sales for special editions, and maintaining relationships with other publishing companies. Publishing companies have many divisions, including, sales, purchasing, publicity, promotion, production, managing editorial, legal contracts Internet development, information technology, human resources, finance, art and design, and audio. |
