Web Hosting - Bandwidth and Server Load, What's That?
Two key performance metrics will impact every web site owner sooner or later: bandwidth and server load.
Bandwidth is the amount of network capacity available, and the term actually covers two different aspects. 'Bandwidth' can mean the measure of network capacity for web traffic back and forth at a given time. Or, it sometimes is used to mean the amount that is allowed for some interval, such as one month. Both are important.
As files are transferred, emails sent and received, and web pages accessed, network bandwidth is being used. If you want to send water through a pipe, you have to have a pipe. Those pipes can vary in size and the amount of water going through them at any time can also vary.
Total monthly bandwidth is a cap that hosting companies place on sites in order to share fairly a limited resource. Companies monitor sites in order to keep one site from accidentally or deliberately consuming all the network capacity. Similar considerations apply to instantaneous bandwidth, though companies usually have such large network 'pipes' that it's much less common for heavy use by one user to be a problem.
Server load is a more generic concept.
It often refers, in more technical discussions, solely to CPU utilization. The CPU (central processing unit) is the component in a computer that processes instructions from programs, ordering memory to be used a certain way, moving files from one place to the next and more.
Every function you perform consumes some CPU and its role is so central (hence the name) that it has come to be used as a synonym for the computer itself. People point to their case and say 'That is the CPU'. But, the computer actually has memory, disk drive(s) and several other features required in order to do its job.
Server load refers, in more general circumstances, to the amount of use of each of those other components in total.
Disk drives can be busy fetching files which they do in pieces, which are then assembled in memory and presented on the monitor, all controlled by instructions managed by the CPU.
Memory capacity is limited. It's often the case that not all programs can use as much as they need at the same time. Special operating system routines control who gets how much, when and for how long, sharing the total 'pool' among competing processes.
So, how 'loaded' the server is at any given time or over time is a matter of how heavily used any one, or all, of these components are.
Why should you care?
Because every web site owner will want to understand why a server becomes slow or unresponsive, and be able to optimize their use of it.
When you share a server with other sites, which is extremely common, the traffic other sites receive creates load on the server that can affect your site. There's a limited amount you can do to influence that situation. But if you're aware of it, you can request the company move you to a less heavily loaded server. Or, if the other site (which you generally have no visibility to) is misbehaving, it's possible to get them moved or banned.
But when you have a dedicated server, you have much more control over load issues. You can optimize your own site's HTML pages and programs, tune a database and carry out other activities that maximize throughput. Your users will see that as quicker page accesses and a more enjoyable user experience.
Web Hosting - Why Backups Are Essential One thing most web site owners have little time for is... anything! Anything other than focusing on their site content and the business or service it supports and the information it provides, that is. That means that administration often suffers, as it frequently must. There's only so much time in the day. But the one thing that you should never let slide are backups. They are like insurance. You rarely need it (you hope), but when you do you need it very badly. Performing regular backups - and testing them - doesn't have to be a nightmare. A little bit of forethought and effort and they can be automated to a high degree. And, they should be tested from time to time. Even when a backup appears to have gone without a hitch, the only way to know whether it's of any value is to attempt to restore the information. If it can't be restored, the backup is worthless. Even when the web hosting company provides the service, there is still some planning involved for the site owner. Hosting companies often rely on one or both of two methods. They backup everything (called a full backup), then backup anything which has changed since the last full backup (called an incremental backup). Of special interest are any configuration files that have been tailored. If you've modified the default installation of a software package, you want to be able to recapture or reproduce those changes without starting from scratch. Network configuration files, modifications to basic HTML files, CSS style sheets and others fall into the same category. If you have XML files, databases, spreadsheets or other files that carry product or subscriber information - about items purchased, for example, or people who signed up for a newsletter - those should get special attention, too. That's the lifeblood of your business or service. Lose them and you must start over. That can break your site permanently. It should go without saying that all HTML and related web site files that comprise visible pages should be backed up regularly. It isn't necessary to record every trivial change, but you can tailor backup software to exclude files or folders. Usually they're so small it isn't worth the trouble. But in some cases those small changes can add up in scenarios where there are many thousands of them. Here again, the backups are worthless if they can't be used. Even if the hosting company charges for doing so, it's worthwhile to test once or twice a year at least to ensure the data can be restored. That's especially true of database backups, which often involve special software and routines. Database files have a special structure and the information is related in certain ways that require backups be done differently. Developing a backup strategy can be straightforward. Start simply and review your plan from time to time, modifying it as your site changes and grows. But don't neglect the subject entirely. The day will come when a hard drive fails, or you get hacked or attacked by a virus, or you accidentally delete something important. When that day comes, the few minutes or hours you spent developing and executing a backup plan will have saved you days or weeks of effort. Writing Tips for all Styles of Writing (writing tips) Most writing tips you will come across are usually geared towards certain writing topics. You can find fiction writing tips, short story tips, and poetry tips among the different ones. These tips are suitable for any style writer. Setting aside a time to write: You have to choose which is best for you. Some writers prefer having a set schedule. They schedule their days as if they are working a 9-5 job. Or some write in the fly and impulsively. Neither way is right or wrong. It is just a matter of choosing the one that fits your lifestyle and writing techniques. Know how to prevent writers block. It often helps keep your mind fresh and writers block at bay when you write about more that one topic at a time. This can keep the creative juices moving and the brain actively thinking about what the next lines are going to be. Writing about topics you know about or have a desire to know about also help the words continue to flow onto your canvas. Writing daily keeps your imagination open and always running. If the words start to become difficult to create, take a break and change the scenery before they are lost. It is easier to add to ideas already in your head than it is to try and start from scratch again. Another great writing tip is to keep a notebook and pen with you at all times. How frustrating it is when you have this fantastic idea but you forget what it is before you can find a pen and paper to write it down. Or you have a dream and wake up thinking that a great story could come of it and then in a flash it is gone. Set daily goals for yourself. Whether you are on a schedule or an impulsive writer setting daily goals will make sure you reach your intended outcome. Daily goals are usually much easier to obtain than weekly goals. If you do not have an education in writing but love to write it will help your career to learn writing basics. Understanding the different writing techniques and styles or basic grammar are imperative parts in a writers career. There are low cost and even free online course that will lead you in the right direction. Another helpful writing tip is to have a proofreader. This can be a family member, a colleague, or a friend. Every writer proofreads there on work over and over but a proofreader will often pick up things that we miss. The writer of a story knows what they want to say; therefore it is to miss an out of place word because you often read what you know it should say instead of what it really says. A proofreader will read the actual words and let you know whether they make sense or need changed. The research you do for an article needs to be accurate and update. A topic with information can be detrimental to your career. It shows lack of responsibility to find correct information. It shows apathetic writing abilities and reflects poorly on your character. The most important tip that you should know is to know what you are trying to achieve with your writing and knowing what its purpose it. By knowing this you will be able to keep focus on the point of your writing. Whether you are writing a story and try to keep reader enthralled with your characters or a late breaking news article by remember the purpose of your story will help you stay focused and on the right track. |
