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.

Yes, Freebies are Real! If you tell someone that something is free, they immediately start looking for the catch. After all, the words of wisdom “there is no such thing as a free lunch” have usually been proven true for people time and again throughout life, and so a healthy cynicism towards free stuff usually springs up with good reason. If you are one of these skeptical types, however, you may be missing out on some really great stuff. The truth is that you CAN get free things that are really and truly free, and yes, actually worth having. You just have to know where to look. OK, here is where the caveat comes in. The definition of “free” often depends on the definition of “cost.” As any economist can tell you, cost really doesn’t only come down to how much money you have to hand over to get something. There are additional costs, like inconvenience and time spent doing something. And true, some freebies have these “non monetary” kinds of costs associated with them. You have to balance all of the costs with the value of the free stuff you are getting and decide if it is worth it to you. The two biggest costs associated with freebies? Time and convenience are at the top of the list. Time is a big factor in many free offers. Companies want a bit of your time in exchange for their free products. Indeed, some companies literally want hours of your time. Have you ever taken advantage of one of those “free weekend vacation” offers in which you received free accommodation in a beach house or condo for a weekend in exchange for suffering through a long presentation and intense sales pitch? For some people, they can handle the presentation and have no qualms about refusing to buy anything and the free vacation more than makes up for it. Other people would rather pay any price to avoid having to listen to one of these spiels. So, while these weekends are freebies, for some people, they cost too much. More often, a company wants your time in a less obvious way – they want you to spend time filling out forms. These forms may simply be your name, address and email address, or they may be very lengthy, quizzing you about buying habits and the like. The reason the companies want you to do these forms is often for market research, and they are more than happy to give you a freebie in exchange for this. Many people find the time spent filling out these forms will worth it to get a great free product. Convenience is the other cost involved with many freebies. Time and convenience go hand in hand in some cases – after all, it may not be especially convenient to fill out form after form simply because it is time consuming, but convenience takes another hit from freebies in the form of spam email. Often, signing up for a freebie can land you on a spam email list, and for some people, getting tons of spam is so inconvenient that they would rather pay full price. The truth about all of these costs of freebies is that the freebie is in the eye of the beholder. You have to decide what you are willing to put up with in order to get a free product. Once you know the limits to your freebie costs, than you can cash in on some really great products that don’t cost you a dime. When you spend five minutes filling out a form and get rewarded with a free DVD player that you have been wanting, you will realize that there are free things out there to be had.

Web Hosting - Why Backups Are Essential One thing most web site owners have little time for is... anything! Anything other than focusing on their site content and the business or service it supports and the information it provides, that is. That means that administration often suffers, as it frequently must. There's only so much time in the day. But the one thing that you should never let slide are backups. They are like insurance. You rarely need it (you hope), but when you do you need it very badly. Performing regular backups - and testing them - doesn't have to be a nightmare. A little bit of forethought and effort and they can be automated to a high degree. And, they should be tested from time to time. Even when a backup appears to have gone without a hitch, the only way to know whether it's of any value is to attempt to restore the information. If it can't be restored, the backup is worthless. Even when the web hosting company provides the service, there is still some planning involved for the site owner. Hosting companies often rely on one or both of two methods. They backup everything (called a full backup), then backup anything which has changed since the last full backup (called an incremental backup). Of special interest are any configuration files that have been tailored. If you've modified the default installation of a software package, you want to be able to recapture or reproduce those changes without starting from scratch. Network configuration files, modifications to basic HTML files, CSS style sheets and others fall into the same category. If you have XML files, databases, spreadsheets or other files that carry product or subscriber information - about items purchased, for example, or people who signed up for a newsletter - those should get special attention, too. That's the lifeblood of your business or service. Lose them and you must start over. That can break your site permanently. It should go without saying that all HTML and related web site files that comprise visible pages should be backed up regularly. It isn't necessary to record every trivial change, but you can tailor backup software to exclude files or folders. Usually they're so small it isn't worth the trouble. But in some cases those small changes can add up in scenarios where there are many thousands of them. Here again, the backups are worthless if they can't be used. Even if the hosting company charges for doing so, it's worthwhile to test once or twice a year at least to ensure the data can be restored. That's especially true of database backups, which often involve special software and routines. Database files have a special structure and the information is related in certain ways that require backups be done differently. Developing a backup strategy can be straightforward. Start simply and review your plan from time to time, modifying it as your site changes and grows. But don't neglect the subject entirely. The day will come when a hard drive fails, or you get hacked or attacked by a virus, or you accidentally delete something important. When that day comes, the few minutes or hours you spent developing and executing a backup plan will have saved you days or weeks of effort.
