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.
Examine the Interior of Publishing Companies (publishing companies) The publishing company can be seen as the backbone of the writing world. Written words seemingly would not have been able to be seen without publishing companies. The publishing company provides a great service to society by publishing and displaying the work of authors. The existence of publishers is obvious, but the interior of the publishing world and its companies is unknown by many people. Publishing is known as an apprenticeship industry, which means that most of the knowledge needed by a publishing professional will be learned with hands-on experience on the job. Generally, information that is learned in one department of a company is useful throughout the publishing house, which gives professionals the opportunity to move between departments. There are many levels to a publishing company and they all have different functions. The administrative level is the first level of any company, and has many responsibilities in the functioning publishing companies. The administrative department is responsible for managing daily operations for publishing executives and management. This responsibility involves interaction with all of the employees from all of the departments, as well as interaction with authors and agents. The administrative employees are required to manage the calendar, maintain organized files, screen/prioritize mail, draft correspondence, make travel arrangements and prepare itineraries, process expense reports, take minutes at meetings and prepare reports. A position as an administrative employee allows a person to have a high-level of understanding of a publishing company, while being visible to executives. Advertising is another division of publishing companies. Most publishing companies have in-house advertising agencies that purchase media space and create and design advertisements. In a publishing company, the advertising department works closely with the marketing directors, editors, and publishers of titles to create an advertising plan that will promote sales of an individual book. Every advertising plan requires research and negotiation to provide the best venues and the most cost-effective methods of advertisement. These employees also work closely with graphic designers, commercial sales representatives, printing presses, and internal staff to facilitate the run of advertisements. The editorial department of a publishing house is one of the most important departments. This department acquires, negotiates, develops, and edits book projects for publication. The daily activities of editorial employees include preparing acquisitions for transmittal to the production department, developing and maintaining relationships with authors, booksellers, and agents, performing general administrative duties, participating in editorial, design and marketing meetings, and reading and evaluating submissions by writing reader’s reports. The editorial department must work closely with all departments. Another division of publishing companies is the marketing department. The marketing department has the responsibility of creating, preparing, and establishing marketing strategies and policies for each title by coordinating the efforts of the publicity, promotion, advertising, online, and sales departments. The marketing department is responsible for preparing all sales presentation materials, audio recordings, fact sheet collation, and promotions, creating and producing additional account-specific presentation materials, researching and establishing relations with new markets, and planning and maintaining sales and marketing schedules. The publisher’s office is also an important department for many publishing companies. The publishers oversee the life cycle of a title from acquisition to production, and onto the sales force. Publishers are responsible for making executive decisions for all titles within assigned imprints while staying within any cost restraints. This department is also responsible for sponsoring book projects, strategies, and initiatives for the publishing company. The subsidiary rights and permissions department is also one of the most important divisions of a publishing company. This department finds additional sources of profit for a given title, including serials, book clubs, and paperback, audio and e-book rights. The daily activities for the subsidiary department include writing submission letters, sending manuscripts, proposals, and books to foreign publishers and agents, coordinating co-productions with other publishers, working with book clubs and sales for special editions, and maintaining relationships with other publishing companies. Publishing companies have many divisions, including, sales, purchasing, publicity, promotion, production, managing editorial, legal contracts Internet development, information technology, human resources, finance, art and design, and audio. Positive Reasons Why Employee Turnover Can Be a Good Thing Employee turnover is the bane of many an organization. If you pick up any business paper, you will find headline after headline screaming about how much turnover is costing companies and how to keep your employees happy and on board to avoid the headaches and hassles of high turnover. The tide, however, is starting to turn. More and more business experts are stepping up and saying turnover doesn’t have to be the end of the world. In fact, in some cases, turnover can be the best thing that ever happened to your company. While some turnover is as bad as traditional wisdom assumes it is, other instances of turnover can be a real positive for your business. How can turnover possibly be a good thing? It all comes down to who is leaving the company, and why. Every office has its workers that are a drag on the business for one reason or another. Maybe the employee is dissatisfied with their job because they have been working it for too long and are overqualified, but they don’t have any room for advancement. Maybe an employee thinks that all of the decisions you are making about the business are the wrong ones and are constantly critical. Maybe the employee just has a personality conflict with the other people in the company and you and other works simply don’t like them very much. When these kinds of employees leave your company, it can be a shot of life into the business. Suddenly, everyone feels hopeful and re-energized because the negative energy in the air is gone. Negative vibes in the office can have a very damaging effect on the staff, and by extension, your business. When the person causing the bad feeling heads for the highway, they take with them all of the problems they created. Not only does the departure of an employee who was causing trouble in the office boost morale for the employees who are left behind because the bad feelings are gone, but it also boosts morale because it creates a job opening within company. If the person who left was a superior to many people in the office, there is now an instant opportunity for advancement. Your workers will step up with their games as they vie for the position, creating new business opportunities for you and generally keeping the spirit high in the office. If you decide to promote from within whenever possible after a turnover, your employees will work harder with the knowledge that they have a chance of moving up. These turnover positives hold true whether the employee in question quit the job or was fired. Who they were in the company and why they left are often much more important in determining whether the turnover was positive or negative. While losing an employee who is bringing everyone else down is a positive thing for your business, losing an employee who was an integral part of the corporation is another. Of course, there are costs involved in a turnover – you have to re-train an employee, and if you hire from outside of the company, you have the costs of advertising the job and the cost of the time spent interviewing candidates. If you are losing employee after employee, and the employees you are losing are the ones who were holding things together at the office, then you need to consider things you can do to reverse the turnover trend. Despite the potential negative side, turnover doesn’t have to be a bad thing for your company. If you manage it properly and if you are dropping employees who have been bringing your business down, turnover could be just the thing to turn your fortunes around. |
