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.

Keeping your Career Intact During Maternity Leave Since, for the most part, maternity leave in this country is not paid, the reality of returning to work after having a baby comes much sooner than it does in most countries. No one wants to return to absolute chaos after they have the baby. Cut down on the stress of going back to work by being prepared. The length of your maternity leave can determine the amount of stress you return to. If you are willing and able it is a good idea to work as long as possible. Of course, everyone is not willing and able. For those that need a longer leave, they should put some plans in place to make the transition back to work smoother. How long you are on maternity leave varies. However, if you plan on returning after you have the baby, you do not want to return to a totally chaotic situation. That means that you want to have the needs of your career in tact before you take your maternity leave. Nothing should interfere with your new addition to the family. While you are bonding and spending time with your newborn you do not want the stress of the office hanging over your head. Lay the ground work so that you do not have to worry about the office while you are away. If you are the boss, you have a lot more stress to manage. It is important that you leave a responsible and capable person in charge of things in your absence. Start training that person to deal with the aspects of your job that they will have to handle as soon as you know you are pregnant. Nothing is more annoying than getting “How do I…” phone calls when you are on maternity leave. If your job is massive, split the responsibilities between two employees. You do not want to split up the tasks among too many people because this can lead to confusion. Two should be the maximum. Be sure to leave things in order. If you are not the most organized person, get that way when you find out you are pregnant. While you are on maternity leave anyone should be able to walk into your office and find what they are looking for in a very short amount of time. If things are messy there is more of a chance for things to go wrong. If you are one of those women that needs to have an extended maternity leave because of pregnancy complications, don’t fret. Enjoy your time offer and relax but also, if you can, try to stay on top of what is happening in your career field. Take an online class and brush up on skills. If you are not sure you want to return to your 9-5, research a new career. The Internet has made working from home a very real and popular option. Search for a job that will allow you to stay at home but also bring in some income. Some jobs, such as Computer Programming, can fetch a pretty penny. Do some research and find out what will suit you best. Work part time until you are ready to have the baby. While some women are eager to take their maternity leave, others are not so excited about it. If that is the case, talk to your employer about working part time until you are due. Some women work until they go into labor. There is no need to do that if you are uncomfortable but if you are having an uneventful pregnancy and love your job, why not?
