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.
A Top Notch Cover Letter Can Get your Foot in the Door If you have ever looked for a job, then you know that it is tough out there. Competition is always fierce, especially for those “dream job” type of positions – great company, great benefits, and great pay. If you want your resume to rise to the top of the pile in the Human Resources department and you want to get that call for an interview, then you need something to make your resume stand out from the rest. The best way to draw attention to everything you have to offer is to have a cover letter that jumps right off the page and grabs the attention of the reader. The cover letter is your first chance to make an impression, so make sure your cover letter makes you the one potential hire that is definitely going to be getting a call. Before you can get into the content of your cover letter, you have to cover your basics. You should never, ever have a “form” cover letter that you use with every resume you send. Tailor your cover letter specifically to each individual employer, mentioning their company and the position for which you want to be considered. Address the letter to the correct person – if you’re not sure who will be doing the hiring, call the company and ask. Don’t assume you can address your letter to the HR department and have that be close enough. Taking the time to write a personal cover letter to each company lets your potential employer know you pay attention to detail right off the bat. Of course, you should also make sure that your cover letter is grammatically correct and free of typos. A sloppy cover letter is a one way ticket to the trash can for your resume. Once you have your basics in order, you can turn your attention to what you are actually going to write in the cover letter. Your cover letter is your sales pitch to the company; you need to let them know why they should bet on your when they hire for the position. One great way to sell yourself is to show off how much you already know about the company. Let them know why you want to work there by specifically mentioning projects the company has been involved in that you admire or talking about the position of the company within the field. As you show off how much you know about the company, draw attention to the ways you can actively help the company grow and succeed by drawing parallels between your experience and their work. After you have shown that you have done your homework and know about the company, go into some detail about the unique aspects of your work history. Draw attention to any special achievements or awards and any educational background you have that makes you a good candidate for the job. Remember, your resume will be attached to the cover letter, so you don’t have to go into great detail. Just pick out the highlights that will make the reader want to turn the page and delve into your resume. How you close your cover letter makes as much difference has how you open it. State again exactly what job you want to be considered for, and suggest that you come in for an interview. You can also suggest a few dates and time for an interview to show that you are eager to move on to the next step. You should also give a time and date that you will call to follow up on your resume. A pleasant closing and your signature seal the deal on your winning cover letter. Software company patent A Software Company Patent is the Door to a World of Confusion There is no universal understanding of exactly what a software company patent is. In general, owning a patent allows a company certain rights (or exclusivity) for a prescribed amount of time. Individuals or corporations seeking a patent must apply for a patent in each and every country in which they wish to have one. Unlike copyrights, patents are not automatically granted to applicants and can take quite a while in order to be approved. Another thing to remember, particularly with a software company patent, is that a patent may issue in one or more of the countries in which you've applied but not all of them. The real problem lies in the fact that there really is no central agreement about what a software company patent actually grants among any of the nations so those who are awarded patents may not be getting exactly what they think they are getting in the process. With no universal agreement there really can't be universal enforcement about the laws and the rights surrounding a software company patent. The growth of Internet business and e-commerce in general has led to many patent applications for software, particularly software that was designed for specific business applications. The problem is that while the cases are granted and successfully tried and defended in some countries, other countries offer no enforcement or legal recourse for those who do not honor the software company patent even if the patents were granted in those countries. The fine line between nations about what is and isn't patentable is another challenge when it comes to establishing and honoring patents. In other words, the issue of a software company patent is a rather confusing process at best. Patents differ greatly from copyrights, which are issued automatically and recognized and enforced internationally. Copyrights protect the source code of software from being copied and registration is generally not required in order for your work to be protected. Lately there is a new term, copyleft, which is an obvious play on words and represents the rights to not only redistribute the works that are covered by this but also to modify and freely distribute those modifications. This term is very much in the spirit of many open source types of software and music. The catch for copyleft protection is that the newly created work be distributed in the same manner and spirit in which it was received. In other words if you were freely given the software, then you must freely provide the improvements and modifications you made to that software. Of course this is a long way from the idea of a software company patent. It is also important that you are sure you understand exactly what you are applying for as far as your patent goes. Different countries will grant patents for different things and those are closely regulated and carefully regarded when it comes to software-know what you are applying for and understand what you are being granted. A software company patent means different things to different people in different places and it nearly impossible to get other countries to honor a patent that they would not have granted at the same time they shouldn't expect other countries to honor patents based on their decision to do so either. One unfortunate circumstance surrounding patents is that there seems to be an unequal and obvious disparity between the haves and the have not's. Patent enforcement for software, unlike literature and music is largely subjective. In literature and music, it is rather obvious that the copyright has been abused or that the work has been copied, this isn't as simple with software which is one other reason that software company patent is such a hotly debated subject in the software industry. |
