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.
Web Hosting - Email Issues When you build a web site, you often provide a means for users to communicate with you. One of the most common 'add-ons' to a web site is the addition of some kind of email access. Email is used to sign users up for newsletters, provide communication for administrative issues and a hundred other uses. But, as everyone sadly knows, email problems can occur. Virus infection is among the most common, though the situation is actually better today than in the past. Huge efforts, and some progress, has been made over the past 10 years to reduce the number and severity of virus attacks. Hackers haven't surrendered, far from it. But they're on the defensive like never before. Many of those viruses were (and are) spread through email, usually in the form of email attachments. That's the source of the now-common advice never to open an attachment from someone you don't know. Professionals will often extend that advice to suggest you never open an attachment that's unexpected, even if it's from someone you know. Well-meaning, but computer-challenged friends often accidentally forward virus infected emails. Spam has taken over the top spot for email annoyances. It's estimated by various different professional sources that 92-97% of all email sent today is spam. While the definition varies, spam is generally regarded as any unwanted commercial email sent by someone whom the recipient doesn't know or have a business relationship with. Spam clutters email inboxes, requires people to sift through to find valid messages, and often contains offensive messages in some form. But, it's a fact of life and isn't going away anytime soon. Even though laws are in place, thousands of spammers continue to risk fines or jail for the chance of making money from that small percentage who will open the unwanted email. Other forms of email problems are even more severe for many web site owners. When the mechanisms fail that they rely on to send and receive messages to and from their users, that's a problem. Dealing with those problems can range from sending an email or instant message to an administrator, to tracking down the right person to get your site removed from a blacklist. Email is the communications vehicle of choice for millions everyday. When the system burps, someone has to take time to do something about it. Often, that means relying on a person who is already overburdened with too many issues to resolve. So, besides pointing out some sad facts or complaining, what's the point? All of the above shows just one more area you should look at when selecting a web host or deciding whether to move to another. Just as with server or network administration, companies vary in their ability to deal with email-related issues. Some are responsive and super-competent. Others, are simply indifferent or worse. And many are in between. Email administration, like server maintenance or network management, is a professional specialty. Skill in one does not necessarily mean quality work in another. Finding a web hosting company and/or system that has few email problems, and solves them quickly when they occur, is an important task. Spend some time researching who provides superior support in email. You'll be happy you did. Being Effective in Your Persuasive Writing (persuasive writing) The goal of persuasive writing is to have the ability to influence or change a persons mind with your words. You encounter these in your normal everyday life. Whether it is a politician trying to convince you to vote for them, a commercial for a company that wants you to buy there product, or from your children trying to explain the reason why they should be allowed to go to that concert, persuasion is all around. You may even use the power of persuasion on yourself, like deciding why or why not you should eat that last piece of pizza or if you really need to buy another white shirt even though it is a really good deal. Everyday you have to decide on whether one choice is better than another and why. To succeed in your persuasive writing venture you need to follow a few simple rules. You must have focus. Decide on what position you are trying to persuade. Are you for or against the topic your writing about? Choose a side and stick with it. Arguing both sides of the fence will be detrimental to your persuasion. There are three techniques that you will need to use to have convincing persuasive writing. Now you need to provide facts and evidence to support your writing. Statistics and examples are used to provide the reason people should choose you position and believe your writings. You can also include facts and evidence that demonstrate why the opposition is wrong. This should be eased into. Remember you are trying to persuade and convince them on why you position is better not offend or alienate them. This is called the logos technique of persuasion writing. Another persuasive writing technique is ethos. This is where you have to prove yourself to be a creditable person. To be able to make your readers believe that they should have confidence in what you are telling them. The best way to prove your credibility is to provide true and undisputable facts, be articulate, and explain why you are capable of proving this information to them. Pathos is the third technique you will use in your writing. This will appeal to the emotions of the readers. This can be the most important technique but also the most critical. It must be used with caution or you can just as easily turn the readers against you as you could bring them with you. Appealing to your readers emotions can be tricky. This must be done subtly To work this effectively you must have the ability to make the reader feel your emotions, the joy, the pain, the hurt whatever the case maybe. You need to pin point your target audience and write to appeal to them. What sounds interesting and persuasive to a teenager most likely will not work with a middle age woman. Whether you are targeting men or women will make a difference in you writings. Identify with your target audience. An example of this would be “only the cool kids will be wearing product XYZ” or “we know as a respectable home owner you will want to…..” By identifying with the intended audience it pulls them into what you are writing and how or why it pertains to them. Persuasive writings can be a challenge. You have to objective and opened minded to other positions of the topic at hand even though sometimes you don’t want too. Remembering you goal is just to persuade them why yours is better. This does not necessarily mean that the opposition is bad or wrong, just that yours is a superior choice. |
