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.
Working on Your Own Time: It’s What Freelancing is About (freelance jobs) Do you have a busy life? Do you wish that you could schedule your work around the rest of your priorities? You work to make money so that you can live. You have no choice but to pay for housing and food and other life necessities. Because you need the money, work tends to creep up to the top of the priority list. Other things are more important though. Freelance jobs allow you to put work where it belongs on the list of priorities. You can play with your kids when they’re home, enjoy doing the things you enjoy outdoors while it’s daytime and spend your Sunday mornings at church instead of behind a counter. The work still needs to get done, but you can do it when you have time instead of from nine to five, Monday through Friday or worse, whenever you’re put on the schedule. Kinds of Freelance Jobs Do you have the appropriate skills and abilities to work at freelance jobs? There are many, many different kinds available. Those with professional degrees can consult. While the jobs that result from extensive education generally lead to many hours working for a good salary, your education can lead you in another direction. If you can manage to find the clients, you can work by appointment only, guiding those who do not have the experience or education that you have. If you are not a professional, you may still have the appropriate talents that will get you into freelance jobs. Writing is a very popular freelance opportunity. You live in a world that relies on the written word. You do not go through a single day without reading a considerable amount of text. Someone needs to do all of that writing, and much of it is hired out to freelancers. Actually, any skill that you possess may be suited to freelance work. Check out a few job boards and find out who’s hiring. Tips of the Trade Freelance jobs are out there, but so is the competition. To get yourself to the top of the hiring list, there are a few things you can do. First, use any experience you have to your advantage. Even if a previous job was short term or didn’t seem significant to you, you gained experience there. Let the employers know about everything you can do. Another thing you must do as a freelancer is to be very consistent and organized. An employer will be much more likely to rehire you if you turn out a good product. Everything you turn in should be clear and professional. Always meet deadlines. While most of the freelance jobs are extremely flexible, allowing you to work at your convenience, there are still deadlines. The work needs to be finished when the employer asks for it. Most of the qualities that will get you more freelance jobs only require common sense and a good work ethic. Living on Sparse Paychecks One downside of freelance jobs is that they are not necessarily consistent. Especially if you jump from one job to another, working for different companies, you will not have any guarantee about how much you will get paid each month. The flexibility may or may not be worth the uncertainty of freelancing to you. If you can manage to save effectively, the distance between paychecks won’t matter. If you do get frustrated about always wondering where the next paycheck is coming from, just remind yourself that the trade off is getting to enjoy more precious time not tied to a desk. There are definitely pros and cons when it comes to freelancing. You just need to decide how important it is to you to prioritize your life around what really matters to you. Web Hosting - Unix vs Windows-Based Hosting, Which Is Better? An operating system functions largely out of sight, or at least is supposed to. It doesn't matter to non-geeks how a file gets stored, or how memory is used, or how simultaneous processes share the limited resources available on a computer. These are among the basic functions of any operating system. Yet, you can find very passionate supporters - who offer very detailed lists of pros and cons - for every operating system. Why? Because, though the low-level functions of an operating system do their work out of sight, there are many other features that rise to visibility. Sometimes, they do so when they're not supposed to. Weighing the pros and cons objectively could consume a book. But to select a web host operating system, a manageable level of considerations apply. They can be weighed even by those who don't know a processor queue from a pool cue. Learning Curves For most web site owners, administering the site/server is just overhead. It's not something they take pleasure in doing and they have plenty of other things to worry about. Many wouldn't know how and have no interest in learning (rightly so, given their priorities). Consequently, ease of administration is paramount for such people. Whether a Unix-based site (usually Linux these days) is easier to administer than Windows depends on your current skill set and the type of tools and level of access the web hosting company provides. But in general Linux is more difficult to install and maintain than Windows and the learning curve is steeper. FTP and Control Panels Often, you don't have to care. For many, the operating system is fairly transparent. FTP file transfers to get a new web page up to a Windows server are very much like they are to a Linux-based site. The user/administrator simply doesn't see what's behind the curtain. Many companies provide other utilities that completely mask any awareness of the operating system underneath. When that's the case, the web site owner has no reason to care, until or unless they need or want to go 'inside the black box'. Performance Performance issues can be relevant in selecting which operating system host type to choose. But for the most part, that aspect is outside the web site owner's control. Overall performance can be good or bad on either system, depending on many factors that the publisher will rarely see. The issue is a wash, as far as tipping the scales is concerned. What is more likely to be seen by a web site owner, at some point in their (and their site's) development is the database product that can be used to store information. Databases Microsoft SQL Server is relatively simple to use, yet extremely powerful and can deliver great performance. But it doesn't run on Linux. At least, not without special software to emulate Windows, which usually kills performance. On the other hand, with a bit of time invested, MySQL isn't significantly more difficult to learn than MS SQL Server and there are many free installations. Cost may well outweigh other considerations for most on this issue. Programming Languages Last, but not least, there are differences in programming languages that can be (or at least typically are) used on Windows vs Unix. If you have programmers who are skilled in Visual Basic, ASP and other Microsoft technologies, then a Windows-based host will be your preferred choice. For Perl and PHP programmers, Linux is the more common platform of choice. No single factor can push you to one versus the other operating system. And, in the long run, it isn't the primary consideration, unless you just enjoy playing with operating systems. |
