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.
Steps on Reinventing yourself to Land a Better Job Having a decent job can greatly improve the quality of your life. You probably spend a fair amount of time at work. With that in mind, you do not want to be miserable when you are at work. If you want a better job, make yourself more attractive to employers. This task may be easier than you think. Start making some simple changes and watch the job offers begin to appear. The number one way to reinvent yourself in order to land a better job is to reform your attitude. Even if you are working at a nightmare of a job at the moment, you need to fight to stay positive. That negativity can be seen a mile away. You may not realize it but your face expression, posture and quality of work give off your frustration. This attitude is the first thing that has to go. Simple ways to change the way you feel about your current job include being on time and in uniform or proper dress code. These are two easy steps that will give you more pride about yourself. If you are out of dress code and late, you are not just making statement about the job. You are making a statement about yourself. Change these aspects of your working environment and you will be on your way to increasing positive energy. Take some classes. Whether you have a degree or not, brushing up on skills is always a good idea. No matter what your schedule is like, you can find time for a class or two. Use the Internet and take online classes if time is a major issue. Work at your own pace and pick up new skills. A degree or a couple of classes will make you more attractive to employers. Move away. If you are tired of dust collecting on your Communications degree while you wait tables, move to a place where your degree is more marketable. Find an area where the job market is fertile. When the economy goes south, certain job types are completely eliminated. If you are eager to find a better job you may have to go somewhere else to do it. Apply for higher positions in the company that you currently work for at the moment. Even if you are not really that thrilled about the current company you work for, while you are there you should make the best of it. Get as much experience as you can so that you will have a nice extensive work history to refer to when you are looking for a new job. If you want a better job, do some networking. Take advantage of the people that you know that have better jobs. Surround yourself with people that are working at jobs that they enjoy or are successful at. This is a great way to pave the way for yourself to get a better job. Figure out what type of job you want before you start looking. Narrow down the search and target the positions that fall in line with the jobs that you are most interested in. If you a constantly saying that you want a better job but don?t have any idea what the better job is, you are not going to be very successful in you search. Have a job in mind before you start your search. Join networking sites. These sites can be used for networking for jobs among other things. Be sure that you take the professional route when you put up your page. Let employers know that you are serious about finding a job. Do not post pictures of yourself at parties or in questionable positions.
