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.
Ten Top Things That Make for a Great Employee If there is one thing that everyone can agree upon in the job market it is that great employees are hard to come by. Whether you are an employee yourself and you feel like you are always pulling the weight of the other people in the office or if you are a boss who is wondering how you can actually get some people on board who can do the job, you know that great employees are at a premium. But what exactly makes an employee great? These ten top things are guides to bosses looking for greatness in a new hire and for employees trying to get noticed in the workplace and be the kind of employee who has the potential to move up in the company chain. The first thing that makes an employee great is that they are always dependable. Great employees do the job they are supposed to do every time, and no one has to worry that they don’t deliver the goods. A great employee can be counted to always have their work done right, when it is supposed to be done – it is a forgone conclusion that they will, and no one else has to spend any time worrying about it. The second thing to look for in a great employee is that they are a team player. A great employee isn’t one who is constantly looking for attention or hogs the spotlight. Instead, a great employee works with everyone else to make sure that the things that need to get done do get done, for the good of the company. The third mark of employee greatness is that they know how to take direction. Great employees know how to take criticism, direction and advice gracefully and make it work for them when doing their job. Fourthly, a great employee can be trusted. They don’t spread office gossip and they don’t dish company dirt. Likewise, they always tell the truth to their employer, even if it lands them in hot water. The fifth sign of greatness in employees is linked to the fourth – a great employee always guards the confidential nature of their business dealings and protects everyone’s privacy. The sixth thing that makes an employee great is that they participate in the day to day life of the office. They don’t bow out of meetings or skip the office birthday celebrations. These things may not be a fun part of working life, and everyone involved knows that everyone else has some place they would rather be – but a great employee wouldn’t be any place else. In seventh place comes the fact that a great employee gets along with other employees. Every office has one person that is in everyone else’s business and talks to loud on the phone and generally stirs things up and gets under everyone’s skin. This kind of employee zaps office morale – a great employee is a good co-worker to everyone. The eighth thing a great employee has is good working skills. It may sound obvious, but a great employee has the abilities needed to do their job, and they constantly seek ways to improve, like going to training seminars or seeking further education. Great workers have great skills. The ninth thing that leads to employee greatness is tact and decorum. If there is a problem in the office, a great employee doesn’t make a scene in front of everyone else. A great employee will deal with such issues with privacy and diplomacy. Further, a great employee doesn’t tell tasteless, political or religious jokes, nor do they send emails that tell these kinds of jokes. Last but not least, a great employee has a great attitude. Bad attitudes bring everyone down. A great employee helps make work great for everyone else by having a good spirit about their job. Web Hosting - Redundancy and Failover Among the more useful innovations in computing, actually invented decades ago, are the twin ideas of redundancy and failover. These fancy words name very common sense concepts. When one computer (or part) fails, switch to another. Doing that seamlessly and quickly versus slowly with disruption defines one difference between good hosting and bad. Network redundancy is the most widely used example. The Internet is just that, an inter-connected set of networks. Between and within networks are paths that make possible page requests, file transfers and data movement from one spot (called a 'node') to the next. If you have two or more paths between a user's computer and the server, one becoming unavailable is not much of a problem. Closing one street is not so bad, if you can drive down another just as easily. Of course, there's the catch: 'just as easily'. When one path fails, the total load (the amount of data requested and by how many within what time frame) doesn't change. Now the same number of 'cars' are using fewer 'roads'. That can lead to traffic jams. A very different, but related, phenomenon occurs when there suddenly become more 'cars', as happens in a massively widespread virus attack, for example. Then, a large number of useless and destructive programs are running around flooding the network. Making the situation worse, at a certain point, parts of the networks may shut down to prevent further spread, producing more 'cars' on now-fewer 'roads'. A related form of redundancy and failover can be carried out with servers, which are in essence the 'end-nodes' of a network path. Servers can fail because of a hard drive failure, motherboard overheating, memory malfunction, operating system bug, web server software overload or any of a hundred other causes. Whatever the cause, when two or more servers are configured so that another can take up the slack from one that's failed, that is redundancy. That is more difficult to achieve than network redundancy, but it is still very common. Not as common as it should be, since many times a failed server is just re-booted or replaced or repaired with another piece of hardware. But, more sophisticated web hosting companies will have such redundancy in place. And that's one lesson for anyone considering which web hosting company may offer superior service over another (similarly priced) company. Look at which company can offer competent assistance when things fail, as they always do sooner or later. One company may have a habit of simply re-booting. Others may have redundant disk arrays. Hardware containing multiple disk drives to which the server has access allows for one or more drives to fail without bringing the system down. The failed drive is replaced and no one but the administrator is even aware there was a problem. Still other companies may have still more sophisticated systems in place. Failover servers that take up the load of a crashed computer, without the end-user seeing anything are possible. In fact, in better installations, they're the norm. When they're in place, the user has at most only to refresh his or her browser and, bingo, everything is fine. The more a web site owner knows about redundancy and failover, the better he or she can understand why things go wrong, and what options are available when they do. That knowledge can lead to better choices for a better web site experience. |
