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.

Positive Reasons Why Employee Turnover Can Be a Good Thing Employee turnover is the bane of many an organization. If you pick up any business paper, you will find headline after headline screaming about how much turnover is costing companies and how to keep your employees happy and on board to avoid the headaches and hassles of high turnover. The tide, however, is starting to turn. More and more business experts are stepping up and saying turnover doesn’t have to be the end of the world. In fact, in some cases, turnover can be the best thing that ever happened to your company. While some turnover is as bad as traditional wisdom assumes it is, other instances of turnover can be a real positive for your business. How can turnover possibly be a good thing? It all comes down to who is leaving the company, and why. Every office has its workers that are a drag on the business for one reason or another. Maybe the employee is dissatisfied with their job because they have been working it for too long and are overqualified, but they don’t have any room for advancement. Maybe an employee thinks that all of the decisions you are making about the business are the wrong ones and are constantly critical. Maybe the employee just has a personality conflict with the other people in the company and you and other works simply don’t like them very much. When these kinds of employees leave your company, it can be a shot of life into the business. Suddenly, everyone feels hopeful and re-energized because the negative energy in the air is gone. Negative vibes in the office can have a very damaging effect on the staff, and by extension, your business. When the person causing the bad feeling heads for the highway, they take with them all of the problems they created. Not only does the departure of an employee who was causing trouble in the office boost morale for the employees who are left behind because the bad feelings are gone, but it also boosts morale because it creates a job opening within company. If the person who left was a superior to many people in the office, there is now an instant opportunity for advancement. Your workers will step up with their games as they vie for the position, creating new business opportunities for you and generally keeping the spirit high in the office. If you decide to promote from within whenever possible after a turnover, your employees will work harder with the knowledge that they have a chance of moving up. These turnover positives hold true whether the employee in question quit the job or was fired. Who they were in the company and why they left are often much more important in determining whether the turnover was positive or negative. While losing an employee who is bringing everyone else down is a positive thing for your business, losing an employee who was an integral part of the corporation is another. Of course, there are costs involved in a turnover – you have to re-train an employee, and if you hire from outside of the company, you have the costs of advertising the job and the cost of the time spent interviewing candidates. If you are losing employee after employee, and the employees you are losing are the ones who were holding things together at the office, then you need to consider things you can do to reverse the turnover trend. Despite the potential negative side, turnover doesn’t have to be a bad thing for your company. If you manage it properly and if you are dropping employees who have been bringing your business down, turnover could be just the thing to turn your fortunes around. |
