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.
Communication Key to a Better Work Environment Everyone knows the story of A Christmas Carole. On Christmas Eve, poor Bob Cratchit, who is working late again, spends his day working up the courage to ask his boss, Mr. Scrooge, if he can have Christmas Day off from work to spend with his family. When he finally does get up the nerve to ask, Mr. Scrooge lets forth a tirade over lazy people using Christmas as an excuse to have a day a off from work. This fictional story unfortunately rings true for a lot of people who have to work up the courage to ask for things from their employers. An employee who has to feel about their employer the way Bob Cratchit felt about Mr. Scrooge is not a very happy and productive employee. To get the most of out of your workers, you have to create a much more hospitable working environment. To create a better working environment, keeping the lines of communication open is absolutely crucial. How does communication work in your office? Do you get the impression that everyone is walking around on eggshells around you? While this kind of fear from your employees may be good for your ego in some senses, it is really bad for your business. When your employees don’t feel like they can talk to you, you will lose control over what is going on with your business. You may be the boss, but your employees are the ones who are actually on the front lines. To know what is really going on out there, you need your employees to communicate honestly with you. If they feel that you are unapproachable, they will hide problems and concerns from you, and you won’t be able to act to fix them. You can’t expect to run your business with half of the information about what is actually going on, and so your business will suffer for your “mean boss” routine. There are still other problems with creating an office environment in which your employees feel like you are unapproachable. In general, there will be a dark cloud over the office when you are around. The stress will keep employee morale low, and employees with low morale are employees with low productivity. Besides, who wants to work hard for someone they cannot approach or who doesn’t show they any respect? Shutting down those lines of communication will definitely affect your bottom line as employees “phone it in” because they don’t feel invested in making your business a success. If you want a better working environment, you have to improve the lines of communication. If there has been a communication breakdown in the past, take the time to address it with your staff. If you staff is small, talk to them each one on one, letting them know that your door is always open and that you want more regular communication with them. If you have a larger staff, schedule a meeting to address the issue. Weekly office meetings are a great way to keep communication channels open and swap ideas in the office environment. If weekly meetings are not feasible, find some way of touching base with your staff on a regular basis, either through weekly emails or a weekly newsletter. Also, you should encourage your staff to communicate with each other. Sharing information among the staff is a great way to generate fresh ideas and fresh approaches to problems. If your office is suffering from a communication problem, make nipping it in the bud a priority. The pay off will be more productive workers and a whole lot less stress. Who knew work could actually be a pleasant place to be? The Road to Riches – Or at Least Success - In writing (how to become a published author) Getting published is the first step on the road to becoming a writer. It’s an exciting day when you receive your first paycheck for something you wrote. It’s a stamp of approval on your ability to write the meaning of the everyday for the general public. If you want to know how to become a published author, read on. It can be a difficult and frustrating road, but the destination is well worth the journey. Starting Small The first thing to remember when wondering how to become a published author is that beginning should look like a beginning. Don’t expect instant recognition or huge payment for your first efforts in the writing world. You will learn as you continue to write and get feedback. Don’t always expect feedback either. You will have to become your own critic to some extent. The following list includes great opportunities for publication as you improve your writing skills. Newsletters As you learn how to become a published author, your first lesson may be that you won’t always get paid. When you are first starting out, your best opportunities may be with free publications that only accept donated work. Many newsletters are created by non-profit organizations. They need donated time from several sources in order to keep the public informed about their work. You could start your practice there. You can also start the process towards name recognition. Newspapers Newspapers are also a good place to begin your publications. Reporting jobs are difficult to land and may not be worth the time and effort that they require, but you can start with letters to the editor for great practice. You’ll see your name in print if you can write a clear letter addressing relevant topics. That could lead you to a relationship with the editor so that you can move into a few freelance jobs. Magazines As you query magazines for possible publication opportunities, you will do well to include some of your already published work. Whether you’ve been compensated or not, your name in print along with some representative writing will help you get an interview with a magazine editor. Now we can talk about how to become a published author for money. Magazines start writers at low wages with the opportunity to increase. Online Publications Online publications work in much the same way. You will probably find job postings on job boards. If you can demonstrate that you have been published somewhere before your chances of landing a paid job will increase. Anthologies As your skills improve, you will be able to step into jobs with books. Anthologies are filled with skillfully written pieces along some subject line. You will need to use all of your capabilities you have learned so far as in writing for an audience and creating a tone acceptable to the publication. If you can do that, you will start to enter into the world of books. You may want to stop there, or you may want to take your work further. Books Writing your own book will take time and work. As you think about how to become a published author, remember that you do not necessarily have to become a book author. Writers work in all fields, and some are limited to one or two. If you have enough motivation and capability, book writing can be a lucrative field to enter into. If you’d rather stick to short term projects though, stick with the magazines and other similar publications. If you need more information about how to become a published author, check out specific information about any of the above genres. The internet is a great source, but you can also support other writers monetarily by visiting your local book store. |
