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.
Free Copyright Music Free Copyright Music Means Deeper Well for Artist Inspiration Free copyright music is often mistaken with domain free music or music in which the copyright has expired. A copyright is in place for the lifetime of the author plus 70 years. If there are more than one writer's for the music, the copyright will be in effect for 70 years after the death of the last surviving contributor. While this rule was set in place in order to ensure that the heirs of the author would also benefit from the royalties after the music's writer or composer was no longer living it is important to remember that these laws are the current laws and music written at different points in time are most likely subject to different copyright laws. When searching for free copyright music it is always a good idea to search through music that is very old rather than focusing your search on more recent musical selections as they will most likely still be under copyright protection. It is important to remember when using free copyright music or public domain music that you must be certain the copy you are using is within the copyright period. Any music that was published before 1922 is public domain music. This does not however include derivatives or new versions of that music which may still be under copyright protection. Finding a copy of the music with the copyright date included, if that date is prior to 1922 is the best route to ensure that you are in compliance with current copyright laws and not infringing on someone else's copyright. It is also important to keep in mind that written music is protected differently than recorded music. Almost every sound recording that has been copyrighted in the United States is protected until 2067. If you absolutely need a sound recording you should either purchase one or make one of your own. There are some free copyright music that will allow free use of the music whether written or recorded, you must be thorough in your search for this music however as it quite rare. Another thing to consider is that copyright laws in the United States are different than they are in other countries and if you wish to use music that is or was under copyright in another country you must follow the laws that apply to the particular piece of music you wish to perform. Free copyright music is available in almost every country and many genres; the trick is in finding great sources where you can easily find this music. There is a project called Mutopia, which operates like project Gutenberg. Mutopia provides free copyright music rather than books however. The Gutenberg project also has a section that is devoted to free sheet music in addition to its wonderful resources for books. Each of these projects provides excellent resources for those who find themselves in need of free copyright music for whatever reason. Whether you are a musician who is seeking inspiration from the music of old or hoping to find a composition, which you can rearrange and make your own, there are many ways in which you can go about achieving your goals that will not violate current copyrights. The key is in learning the laws both where you live and in any countries in which the music you seek to modify. By choosing selectively and listening to your options with an open mind and seeing things with a creative eye, you will find a huge world of opportunity available to you as a musician. Isn't it amazing how free copyright music can have such an effect on your ability to create music that you may someday copyright? 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. |
