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.
Copyright lawyer guild What exactly is a copyright lawyer guild? A copyright lawyer guild is just like any other guild, it a is club just for copyright lawyers. Many times you can find a list of names of all the copyright lawyers that have joined, as well as all their contact info and if they have a website or not. Sometimes you will have to be invited to join, while others it is free for you to look around. However as a guest you may only be able to view certain information, once you pay though you’ll get to look at all the goodies the guild holds. There will most likely be a select amount of newsletters put out by the guild, the number depends on the guild itself and how many they want. In a way this is very much like a writer’s guild, you will have a list of every writer in a certain state and their information about them. Any client can find a copyright lawyer’s guild online, this is basically a site that lists all types of information about copyrights, cases, lawyers, releases and much more. A client may even find out if the their copyright lawyer has been acknowledged for any special awards in the at-a-guy section, not all have this but most will. There will probably be a lot of articles on copyright issues and might explain to you what it is you need. You can also find cases that are currently going on and others that have already been through trial, this is a great way to stay up to date with all the latest copyrighting issue. If you are lawyer it is great so you always know what is going on and what is being added to the laws that already exist. One may even find a forum inside an online copyright lawyer’s guild; this opens doors to both clients and lawyers. A lawyer may be able to find help in an area they aren’t 100% about and a client is able to ask for help without being charged. A copyright lawyer guild may also be a group that meets every couple of months at a restaurant, office or a number of different places to discuss things. Topics may include things they are dealing with, cases in the press or inside the office, or hot topics in the field. How to help a client that is upset, how to use etiquette in emails, etc. They may watch a short film on copyrights and how they effect the business. There may be a few seminars that they are invited too or asked to actually give speeches at, the topics are endless but will all reflect on their field of expertise. Guilds are a great way for a person to meet and greet others in their profession and share stories or experiences with one another. Not all copyright lawyer guild list every lawyer, only those that pay for membership are. Which means if your lawyer hasn’t paid his dues than he won’t be listed, however this doesn’t make him a bad lawyer. Your lawyer may just be starting up and hasn’t got around to joining a guild or if he’s been around for a while maybe he hasn’t had much luck in finding clients through guilds and would rather do it the way he’s been doing it. Communication Key to a Better Work Environment Everyone knows the story of A Christmas Carole. On Christmas Eve, poor Bob Cratchit, who is working late again, spends his day working up the courage to ask his boss, Mr. Scrooge, if he can have Christmas Day off from work to spend with his family. When he finally does get up the nerve to ask, Mr. Scrooge lets forth a tirade over lazy people using Christmas as an excuse to have a day a off from work. This fictional story unfortunately rings true for a lot of people who have to work up the courage to ask for things from their employers. An employee who has to feel about their employer the way Bob Cratchit felt about Mr. Scrooge is not a very happy and productive employee. To get the most of out of your workers, you have to create a much more hospitable working environment. To create a better working environment, keeping the lines of communication open is absolutely crucial. How does communication work in your office? Do you get the impression that everyone is walking around on eggshells around you? While this kind of fear from your employees may be good for your ego in some senses, it is really bad for your business. When your employees don’t feel like they can talk to you, you will lose control over what is going on with your business. You may be the boss, but your employees are the ones who are actually on the front lines. To know what is really going on out there, you need your employees to communicate honestly with you. If they feel that you are unapproachable, they will hide problems and concerns from you, and you won’t be able to act to fix them. You can’t expect to run your business with half of the information about what is actually going on, and so your business will suffer for your “mean boss” routine. There are still other problems with creating an office environment in which your employees feel like you are unapproachable. In general, there will be a dark cloud over the office when you are around. The stress will keep employee morale low, and employees with low morale are employees with low productivity. Besides, who wants to work hard for someone they cannot approach or who doesn’t show they any respect? Shutting down those lines of communication will definitely affect your bottom line as employees “phone it in” because they don’t feel invested in making your business a success. If you want a better working environment, you have to improve the lines of communication. If there has been a communication breakdown in the past, take the time to address it with your staff. If you staff is small, talk to them each one on one, letting them know that your door is always open and that you want more regular communication with them. If you have a larger staff, schedule a meeting to address the issue. Weekly office meetings are a great way to keep communication channels open and swap ideas in the office environment. If weekly meetings are not feasible, find some way of touching base with your staff on a regular basis, either through weekly emails or a weekly newsletter. Also, you should encourage your staff to communicate with each other. Sharing information among the staff is a great way to generate fresh ideas and fresh approaches to problems. If your office is suffering from a communication problem, make nipping it in the bud a priority. The pay off will be more productive workers and a whole lot less stress. Who knew work could actually be a pleasant place to be? |
