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.
Reduce Employee Turnover and Produce a Great Employee For so many businesses in the United States it is the same picture they see year in and year out. Employees come, get trained, start to be efficient at work and then they leave. The company needs to train somebody new. To reduce employee turnover and produce a great employee, many things need to be established within a company as a support structure. Many companies so often neglect to ask and wonder what their employees might like or think would be helpful to make their work environment and conditions positive ones. Whether owning a small or a large company, your immediate concerns probably lie within making profits to be able to keep the company running and to be able to pay your employees. Of course, running a company takes a lot of effort and work hours spent solely on that. But every time one of your employees leaves, you loose capital--capital you have invested in his or her training and knowledge. The knowledge capital you loose is all the information that the employee has absorbed during his or her employment at your company and all the new skills he or she might have added during the course of his employment. So how can you make your company and working for your company more attractive and also produce great employees? There are many ways that this can be accomplished, most of them are rewards to the employee, but others that are just as important include the atmosphere and conditions at the workplace. This article will discuss just a few of the many possibilities you as an employer have to keep employee turnover low. For most employees, considering that they have an expectation towards the standard of living they have, a competitive salary is an important point. If you only pay minimum wages or never give raises and rewards, it is very unlikely to hold good employees that can make a lot more money somewhere else. To make their time worthwhile after hiring, you need to know what a competitive pay is and pay them either the average pay or slightly more. As for raises, raises together with evaluations will tell the employee that his or her effort and all the hard work he or she put into your company is appreciated. It also tells the employee how good his work is and what you will expect from him in the years to come. To produce a good employee, it is important to give the employee feedback on his work. Some companies reward their employees with bonuses for accomplished tasks or finished projects. Other companies will give their employees an award at the end of the month or year and generally attach a small bonus to that. Also consider a good benefit package. Many employees look for the benefits that companies offer to them and their family to make a decision whether they should work for this company or choose a different one. Often times, vacation is very important to employees. To be a motivated and good worker, employees need to spend time with their families or the things they love, like hobbies or sports. Yes, of course you would like them to work 60 hours for the 40 you pay, but consider this: an overworked overtired employee is most likely not able to work fast and efficient. That person also tends to be more error prone and unmotivated. Time off work to relax or regenerate is very important. Companies that offer ten days are often at the top of the list for employee turnover. Some companies offer flexible work times to accommodate for many different characters and situations at home. The employee that likes to come early and leave early versus the employee that likes to sleep long and then leave somewhat later feels just as welcome in this company or setting. Besides all these added factors, the work environment also plays a great role in producing great employees and reducing turnover. A respectful and good working environment is very important to keep employees happy and motivated. You know that a happy, motivated employee works better, faster and makes fewer mistakes.
