Web Hosting - How To Select A Web Host
As with many purchases, our first impulse when selecting a web hosting company is to go with the cheapest. Hey, they're all alike, why pay more? Au contraire.
There are a number of objective criteria that separates one web hosting company from another and money is only one of them. And not the most important one. Selecting a company based on price alone is equivalent to selecting an auto mechanic on price alone. Sure, he may maintain or fix your car cheaper. But will the car spend all the time in the shop and none on the road?
The first consideration is 'horsepower'. Do they have the capacity to carry your load and deliver decent performance? Most hosting companies will advertise that they have huge bandwidth and hundreds of servers. They're usually telling the truth.
But there's a difference between existing capacity and usable capacity. If they also have thousands of sites with millions of visitors per day the available or free capacity will be much lower. A big pickup truck may be able to tow 5,000 lbs. But not if it's already carrying 4,999.
Be sure to ask about available capacity, and have the prospective company back it up with reliable numbers. If you can't interpret the information they provide, find someone to help you do so.
Next, and a very close second, is reliability. A lot of power is worthless if it's cut often. Outages are a normal part of business. Even Google and Microsoft go down from time to time. The difference is, it happens rarely and they have failover plans. That means, if their site/system does go down it's either up again in a flash, or you never see the outage because a backup system kicks in automatically and seamlessly.
Be sure to grill the company closely about their up time. They'll often tout 99.6%, or some such figure. But, like the on-time figures of the airlines, those numbers can be shaded by adjusting the definition of 'up time'. What matters to you is whether your visitors will be able to reach your site at any time of the day or night they might want to.
Find out what systems, both technical and human, they have in place to deal with failures of all sorts. Servers can go down, networks can fail, hard disks can become defective and lose data even when the other components continue to work fine. The result is YOUR site is unavailable, which is all that matters to you. The web hosting company should be able to deal with all of that and have you up again very quickly.
Last, but not least, is security. With the continuing prevalence of viruses and spam, you need to know that the web hosting company you select has an array of methods for dealing with them. That means a good technical plan and staff who are knowledgeable in dealing with those issues. The old saying: 'an ounce of prevention is worth a pound of cure' is more true here than anywhere else.
All these issues are central to finding a web hosting company that can deliver the services you need. After those criteria are satisfied by a number of candidates, then you can start narrowing them down by price.
The Job Interview ? How to Handle Getting Around a Negatively Asked Question Many dread that day that they have to go for an interview. Looking professionally dressed, acting professional and displaying the knowledge is all important. Employers and interviewers test you for anything and everything that you can think about--from your likes and dislikes to the actual experiences with this type of work to the facts. Most of these questions you can dodge and answer safely and securely. But how about those negatively asked questions, how could you professionally dodge those questions? Often times a reaction to a negative question is what can make or break the deal. Sometimes employers ask these questions on purpose to see what your reaction might be and to be able to determine first of all your character and second of all, if the negative event in your life is related to a good or bad character. So how can you master these questions and possibly pass the tests? One of the most important factors when getting prepared to dodge difficult questions is to be secure and knowledgeable about any points on your résumé and in your life. If you have a good answer prepared for difficult situations that happened in your life, it will be an ease for you to get around negatively asked questions. Whenever an interviewer asks you a negative question, make sure you stay calm and do not answer hastily. Sometimes it is enough to give a very short answer and it does not necessarily need a complete explanation that might get you stuck. The longer the answer you try to make up, the easier you might stumble over something and then fall hard. When trying to get around a negatively asked question, besides that fact that you need to stay calm and give a short answer, try to get to a different topic. Strike up a conversation about your more positive skills and accomplishments and therefore get around that question that might have bothered you otherwise. In some instances, depending on the content of the question, it might even be best to answer truthfully. What if you were asked about staying home for no obvious reason? At least according to your résumé there is no job, no new degree or similar mentioned. Maybe it was for a sick relative or the birth of a baby? Why not use the truth in these cases as an answer. When answering difficult questions you might have to decide often on the spot how to answer. In any case, it will almost never help you to make up a lie for a negatively asked question. A lie can get you into a situation you cannot get out of, but the truth can never get you in a worth situation than you are in by answering the questions truthfully. If you do not want to answer truthfully because you think it can hurt your image, sometimes it then is better not to answer the questions. Try to divert the attention successfully to another more positive topic such as your achievements, earlier project or similar other experiences that led to a positive result. Keep in mind that the interviewer is testing to see if you are a good fit for the company and they do not exactly know you. They know a few facts about you, but the do not know the whole picture and especially not about the more negative things they might want to find moiré information about. So when going for a an interview and trying to get around a negatively question, make sure to be honest or to not get into details if you do not want to discuss the issue, but mainly make sure that you stay calm, do not get excited about it. A calm confident person can easily answer any and all questions that might be posed to him or her.
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.
