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.
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. Copyright music lyrics To Copyright Music Lyrics is to Protect the Wealth of your Future Whether you copyright music lyrics or the notes to a song you have a certain amount of ownership in the song. This is one of the many instances where the copyright affects more than one person and results in being valid until the last remaining person on the project (of course you must be identified in the copyright in order for this to affect you) have been deceased for at least 70 years. The easiest route for musicians is not just to write the notes but also to copyright music lyrics at the same time. This is much better for everyone involved and there is only one registration fee rather than creating a need to register the music and the lyrics as separate entities. For those who are new to the entire process of registering copyrights, owning copyrights and wondering exactly what happens now that you've registered it can seem like either an extremely complicated or confusing process. Many new artists fail to properly protect themselves and their non copyright music lyrics from those who would take advantage of them. If you are hoping to copyright lyrics that you've written for a song, I strongly recommend copyrighting music lyrics and registering them before introducing the lyrics to the music of the song unless you wrote both the lyrics and the music. Doing all of it together is often more difficult, particularly for those who feel more talented or gifted in one area than another but it really does help keep everything together and straight over the long haul. It's also great practice to write your own music rather than focusing only on the righting of words. After all, you had something in mind when you wrote the lyrics (a tune, a melody, something) and only you can truly give the unfinished artwork the justice it deserves. So many people forget how similar creating music is to creating visual art. Both require dedication, visions, purpose, and passion. They require different skills but very similar emotions and qualities in order to do well. Once you've begun to copyright music lyrics there really is no major difference between moving on to the next task, which is actually writing and copyrighting the music to go with those wonderful lyrics. If you're not a great music writer, then it is probably preferable that you find someone who is to work on this project with you. Perhaps your next copyright music lyrics session will lead to some wonderful collaborations and joint ventures. Many times in music the hardest part of any big break is in finding the right partner with whom to work towards your common goals. Most bans fail because they either never shared a common goal or someone in the band changed the goal without consulting anyone else. The vast majority of marriages break up over very similar claims. Perhaps the cruelest point of all to make is that not everyone who can copyright music lyrics will be completely honest about the source of the lyrics or the period of their lives while leading up to that point. The sad news is that we live in a world that isn't going to easily take someone's word that they created those lyrics, particularly if someone else already has a copyright on those very same lyrics. If you aren't the ones writing the lyrics, or the music for that matter be careful that you don't end up trying to pass of copyright music lyrics or notes that aren't your own creation, this could definitely lead to more harm than good in time. More than anything else is extremely dishonest and unbecoming of a musician. |
