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 - Is a Dedicated Server Worth What You Pay? In reviewing web hosting plans, many web site owners are faced at some point with the decision of whether or not to pay for a dedicated server. A dedicated server is one which holds your site(s) exclusively. It's not shared with other sites. You then have the option to put one site or many on that piece of hardware. But the decision is never easy. There are multiple considerations to take into account, far beyond just the higher dollar outlay that inevitably accompanies a dedicated server option. Performance is (or should be) a prime consideration for the majority of site owners. Studies show that when a page doesn't load within about 10 seconds or less, almost everyone will give up and go elsewhere. The delay may be caused at any of a hundred different points in the chain between the server and the user. But often, it's the server itself. In any case, it's important to eliminate the server as a possible bottleneck, since it's one of the few points over which the site owner can exercise some control. That need for control extends further than just performance, however. Other aspects of the user experience can benefit or suffer from server behavior. Security is a prime example. With the continuing prevalence of spam and viruses, a server can easily get infected. Having only your site(s) on a single server makes that issue much easier to deal with. With fewer sites on a server, there is less likelihood of getting infected in the first place. Also, since you will place a higher value on security than many others, it's easier to keep a dedicated server clean and your site well protected. You can use best practices in security to fortify your site. Having other sites on the server that you don't control raises the odds that your efforts are for nothing. One way your efforts can get watered down is through IP address sharing. Less sophisticated hosting services will often assign a single IP address to a single server and multipe sites. That means your site is sharing the same IP address with other domains. That leaves you vulnerable in several ways. Virus or spam attacks may target a particular IP address. If you have the same one as another site, one that is more likely to attract hostile intentions, you suffer for and with someone else. In other cases an IP address range is assigned to the server, with each site receiving its own address from within that range. Though better than the one IP:server scenario, this still presents a vulnerability. Many attacks try a range of IP addresses, not just a single one. But even legitimate sources can give you trouble when you share an IP address or a range. If another site engages in behavior that gets it banned, you can suffer the same fate if they ban the address or range. If the miscreant that shares your server/IP address or range is himself a spammer for example, and gets blacklisted, you can inadvertently be banned along with him. Using a dedicated server can overcome that problem. There's a certain comfort level in knowing what is installed on the server you use, and knowing that you alone put it there. But a dedicated server option may require increased administration on your part. If you're not prepared to deal with that, you may have to pay still more to have your dedicated server managed by someone else. All these factors have to be weighed carefully when considering a dedicated server plan. Making Effective Web Publishing Content (web publishing content) Web publishing content is important for a successful website. The content of a web site can often make or break that site, and it is important to make the site as attractive as possible, without over doing it. The content of a web site must be updated on a regular basis to keep web surfers coming back. Updated web content not only keep surfers coming back, but is also indexed more frequently by search engines. Fresh material is one of the key aspects of successful web publishing content and may generate fresh faces to a web site. One way to update the content of a web site is to update the existing web pages. Providing new content could include updating the conditions of a service, adding a new product or service, or creating a turnkey solution that will save the customer?s money or time. The web content should reflect the most recent information about a business. It is simple to provide changes to the web content, but many web sites provide updates without providing a notice. So, it is indicative to provide a notice of change each time web publishing content is changed. The announcements should be displayed prominently on the web site so that all surfers are able to see. It is also important to write articles for the web site. Articles can be seen as a valuable source for a web site?s success. The articles can be used to educate visitors on the web site and the business, while showcasing the owner?s expertise. Articles can be posted on the web site or used in a newsletter and submitted to other newsletters and web sites for syndication. This web publishing content can be used by other web site owners, which will provide leverage to the articles while generating publicity for the author and the author?s web site, while exposing them to new audiences. Writing an article seems simple enough, but there are many web site owners who are unable to find topics to write on. However, topics may be more evident than most web content writers may think. Topics for articles can be found in the news, in conversations with clients and colleagues, in networking events that are attended, and even in speeches. Blogging is also an excellent way to expand your list of web publishing content. Most web site owners can benefit from learning to blog, learning to start a blog, learning how to gain readers, and learning to make money from blogs. Blogging is becoming one of the most popular tools for showing new content on a web site. A web log can be used to answer web site visitors? questions, inform users about new services and products, and to keep them up-to-date on industry news. Blogs are a great resource for sharing opinions and displaying expertise. The blog can be used to help an owner connect with their web site visitors while generating new web site content. Updating web publishing content on a regular basis is vital to the success of a web site and very important for many web site owners. Articles, newsletter, and blogging should be a part of a regular business schedule, and will work perfectly in keeping a web site owner connected to their visitors. The quality of the web content on a web site can make it more attractive to users or can make it very unattractive to users. Owners should use their expertise to provide writing that is interesting and necessary. Visitors will appreciate the extra effort and owners will get the rewards of maintaining good web content for their users. |
