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. Examine the Interior of Publishing Companies (publishing companies) The publishing company can be seen as the backbone of the writing world. Written words seemingly would not have been able to be seen without publishing companies. The publishing company provides a great service to society by publishing and displaying the work of authors. The existence of publishers is obvious, but the interior of the publishing world and its companies is unknown by many people. Publishing is known as an apprenticeship industry, which means that most of the knowledge needed by a publishing professional will be learned with hands-on experience on the job. Generally, information that is learned in one department of a company is useful throughout the publishing house, which gives professionals the opportunity to move between departments. There are many levels to a publishing company and they all have different functions. The administrative level is the first level of any company, and has many responsibilities in the functioning publishing companies. The administrative department is responsible for managing daily operations for publishing executives and management. This responsibility involves interaction with all of the employees from all of the departments, as well as interaction with authors and agents. The administrative employees are required to manage the calendar, maintain organized files, screen/prioritize mail, draft correspondence, make travel arrangements and prepare itineraries, process expense reports, take minutes at meetings and prepare reports. A position as an administrative employee allows a person to have a high-level of understanding of a publishing company, while being visible to executives. Advertising is another division of publishing companies. Most publishing companies have in-house advertising agencies that purchase media space and create and design advertisements. In a publishing company, the advertising department works closely with the marketing directors, editors, and publishers of titles to create an advertising plan that will promote sales of an individual book. Every advertising plan requires research and negotiation to provide the best venues and the most cost-effective methods of advertisement. These employees also work closely with graphic designers, commercial sales representatives, printing presses, and internal staff to facilitate the run of advertisements. The editorial department of a publishing house is one of the most important departments. This department acquires, negotiates, develops, and edits book projects for publication. The daily activities of editorial employees include preparing acquisitions for transmittal to the production department, developing and maintaining relationships with authors, booksellers, and agents, performing general administrative duties, participating in editorial, design and marketing meetings, and reading and evaluating submissions by writing reader’s reports. The editorial department must work closely with all departments. Another division of publishing companies is the marketing department. The marketing department has the responsibility of creating, preparing, and establishing marketing strategies and policies for each title by coordinating the efforts of the publicity, promotion, advertising, online, and sales departments. The marketing department is responsible for preparing all sales presentation materials, audio recordings, fact sheet collation, and promotions, creating and producing additional account-specific presentation materials, researching and establishing relations with new markets, and planning and maintaining sales and marketing schedules. The publisher’s office is also an important department for many publishing companies. The publishers oversee the life cycle of a title from acquisition to production, and onto the sales force. Publishers are responsible for making executive decisions for all titles within assigned imprints while staying within any cost restraints. This department is also responsible for sponsoring book projects, strategies, and initiatives for the publishing company. The subsidiary rights and permissions department is also one of the most important divisions of a publishing company. This department finds additional sources of profit for a given title, including serials, book clubs, and paperback, audio and e-book rights. The daily activities for the subsidiary department include writing submission letters, sending manuscripts, proposals, and books to foreign publishers and agents, coordinating co-productions with other publishers, working with book clubs and sales for special editions, and maintaining relationships with other publishing companies. Publishing companies have many divisions, including, sales, purchasing, publicity, promotion, production, managing editorial, legal contracts Internet development, information technology, human resources, finance, art and design, and audio. |
