Web Hosting - Sharing A Server – Things To Think About
You can often get a substantial discount off web hosting fees by sharing a server with other sites. Or, you may have multiple sites of your own on the same system. But, just as sharing a house can have benefits and drawbacks, so too with a server.
The first consideration is availability. Shared servers get re-booted more often than stand alone systems. That can happen for multiple reasons. Another site's software may produce a problem or make a change that requires a re-boot. While that's less common on Unix-based systems than on Windows, it still happens. Be prepared for more scheduled and unplanned outages when you share a server.
Load is the next, and more obvious, issue. A single pickup truck can only haul so much weight. If the truck is already half-loaded with someone else's rocks, it will not haul yours as easily.
Most websites are fairly static. A reader hits a page, then spends some time skimming it before loading another. During that time, the server has capacity to satisfy other requests without affecting you. All the shared resources - CPU, memory, disks, network and other components - can easily handle multiple users (up to a point).
But all servers have inherent capacity limitations. The component that processes software instructions (the CPU) can only do so much. Most large servers will have more than one (some as many as 16), but there are still limits to what they can do. The more requests they receive, the busier they are. At a certain point, your software request (such as accessing a website page) has to wait a bit.
Memory on a server functions in a similar way. It's a shared resource on the server and there is only so much of it. As it gets used up, the system lets one process use some, then another, in turn. But sharing that resource causes delays. The more requests there are, the longer the delays. You may experience that as waiting for a page to appear in the browser or a file to download.
Bottlenecks can appear in other places outside, but connected to, the server itself. Network components get shared among multiple users along with everything else. And, as with those others, the more requests there are (and the longer they tie them up) the longer the delays you notice.
The only way to get an objective look at whether a server and the connected network have enough capacity is to measure and test. All systems are capable of reporting how much of what is being used.
Most can compile that information into some form of statistical report. Reviewing that data allows for a rational assessment of how much capacity is being used and how much is still available. It also allows a knowledgeable person to make projections of how much more sharing is possible with what level of impact.
Request that information and, if necessary, get help in interpreting it. Then you can make a cost-benefit decision based on fact.
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. Yes, There Really is a Freebie Santa Claus If you are a cynic when it comes to offers of free stuff, you are not alone. Everyone has had notions like “there is no such thing as a free lunch” and “if it sounds too good to be true then it probably is” drilled into their heads, and for good reason – these things often hold water. On the flip side, there ARE actually lots of places you can score some decent free stuff, if you know where to look and are willing to devote some time to hunting them down. The key to getting the best free stuff with the least amount of hassle is to stick with that healthy cynicism but to also dipping your toe in the freebie pool little by little. But why would anyone give stuff away for free? It is certainly an obvious question, but if you stop to consider it for a moment, you can see that companies actually have a lot of motivation to give away free stuff. After all, if they give you something for free, you are bound to have a little soft spot for their company, and when you are ready to part with some cash, their product may near the top of your list. Also, by giving away free things, companies can convince people to try new products. You might not want to try a new kind of shampoo if you have to pay for it, but you’d certainly be willing to give a free sample a try. You may end up loving it and switching to that shampoo for good, turning you into a paying customer. Another reason a company might give you free stuff is to complete market research. This is where getting free things can get a little complicated for some people because the products may not cost you money, but the offer may cost you a little time. A company might ask you to take a survey of your buying habits before they give you a free offer, or they may ask you to provide feedback on a regular basis as you try their product for free. Some people balk at the time commitment required here, but for other people, filling out some paperwork is a small price to pay for some free stuff. Of course, to convert you into a customer or to communicate with you about market research, a company will have to contact you, which is complicated area number two for freebie lovers. You will almost always be forced to hand over your email address in order to cash in on a free offer, and that is a recipe for opening your inbox up to a barrage of spam (many companies sell your email address to offset the costs of their free promotions, which means the number of people soliciting you can go through the roof very quickly). If you want to avoid this downside of freebie hunting, set up a special email address specifically for your freebie deals. That way all of your spam goes to this one address and your regular email you use with family and friends remains free and clear. One final note of caution about free stuff online: a lot of scammers have hit on the idea of using pretend freebie offers to solicit personal information about people or to convince people to send them money. Don’t send money, even for postage, to a company you don’t know and never, ever give out personal information online. No reputable company is going to ask for your social security number or bank account details for a freebie offer, so don’t hand them out to anyone. When in doubt, skip it and move to the next freebie. |
