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 - When Changing Web Hosts Nearly everyone will want to change to a new web host at some point. It may involve just changing out old hardware for new. It usually means finding an entirely new web hosting company. When faced with that decision there are a number of issues to be considered. Swapping hardware and/or software is a fairly straightforward decision. There are two possible scenarios. Either you maintain your own hardware and software at a facility managed by others, or you are considering upgrading to newer (usually more expensive) systems maintained by others. In either case, it's simply a matter of estimating the cost and the short-term impact versus the long-term benefits. If the system(s) you currently use are short on capacity, sooner or later you'll be sufficiently motivated to make the change. Either the hardware will become unreliable or loaded to the point you'll be forced to migrate, or your needs will expand enough to justify the effort and expense of moving. Similar considerations apply to the scenario in which you rely on the web hosting company for everything, and want to find someone else to rely on. Regrettably, that's a very common situation. Many web hosting companies provide systems and staff that sooner or later fall below an acceptable level. Most people make the decision to change based on emotion. That's not entirely bad. Emotions incent you to take action. But you need to keep a cool head, too, in order to calculate your long-range self-interest. Bearing some minor inconveniences from time to time is usually worth the trade off. When it begins to affect your site to the point you're losing visitors, it's time to make a change. To get a more objective handle on when that point is reached, reach for some numbers. Maintain, or get from the hosting company, a factual report about availability and current usage. If the server is down so much, or so heavily loaded, that it drives your visitors away, it's time to take action. There are other less easily quantifiable but equally important factors, as well. You will at some point need to communicate with one or more persons who help maintain your site. Even if you do all your own server, database and web site maintenance, someone behind the scenes is helping to keep things running smoothly. That's called 'infrastructure'. If the road you drive on has potholes, it's not enough that you can fix your own car. In terms of network bandwidth and availability, server capacity, disk space, security and a whole array of other aspects, the web hosting company has to have competent people who care (and are allowed) to do the job well. When the company's people fall down - because of incompetence, lack of resources or absence of a culture of excellence - or for any other reason - your web site suffers. This issue more than any other is what drives people to seek another web hosting company. Even if you choose well at the outset, things can change. Management changes, staff changes and companies are taken over by other companies. Sometimes, it isn't simply a matter of swapping out an unreliable piece of hardware or software. When it's time to swap out people, you look for the same aspect: doing the job required. How to Use a Sample Written Proposal (sample written proposal) Writing a proposal is not an easy feat. For many, it is one of the most difficult things they will ever do in their entire lives. However, there is help for those who are confused about the proposal writing process. A sample written proposal can be used as a guide for the confused writer, and can help them with the process of writing their own proposal. Proposals usually have seven components, which include the Table of Contents, Mission Statement, Abstract, Statement of Need, Project Rationale Incorporating Literature Review, Project Narrative, and Attachments. All of these features can be found in sample proposals, which provide writers with an example of how these sections should be organized. A table of contents is used to provide a comprehensive guide to the proposal, so that readers are able to find what they need and find areas of importance within the proposal. A sample written proposal is an excellent guide to writing a mission statement. A mission statement should be 50 words or less, and states the mission of the project. The statement is used to clarify and state the project’s primary goal, and allows the reader to instantly understand what the writer is proposing without reading the entire proposal. The second section of a proposal is the abstract. It is vital to a proposal that an abstract is well-written, and initial proposal reviews or “first cuts” are often based on the abstract. The abstract of a proposal should be written after the mission statement, and should be changed over time, as the proposal develops further. Most proposal drafters will see that abstracts should be clear and understandable to all readers, including lay readers, and should be suitable for publication. Proposal abstracts should be written in third person, and should include objectives, methods to be employed, and the possible impact of the proposed project. Statement of need is the next part of a proposal. Many writers could benefit from a sample proposal when writing this section, because some drafters tend to write about more than one problem, or present their problem incorrectly. The Statement of need is the section where the drafter presents the problem that must be solved. In this section, drafters should avoid circular logic in the development of their statement of need, as it decrees that the lack of a solution is the problem. It is important to use logical progression in the statement of need, and the proposer must prove that they have an understanding of the problem. The statement should be closed with a discussion of what else is being done to solve the problem, and lead into the narrative with a description of how your idea is different and essentially better than all others. The Project Rationale Incorporating Literature Review is the next section of a proposal. All samples written proposals will have this section, as proposals must incorporate a theoretical basis with a discussion of literature. The rationale for the project should come from evidence found in the relevant literature. A sample written proposal will show drafters how to develop this section and show them how all proposals should incorporate current research into their projects. The project narrative is the sixth section of the proposal, which has six main sections. Some organizations require different proposal narratives, so in this aspect, it may be better to obtain sample proposals from several different organizations. The six sections of the project narrative section of a proposal include goals and objectives, proposed activities, facilities, resources, and project management, evaluation, outreach and dissemination, and sustainability. The final section of a proposal is the attachments’ section. Generally, attachments include the bibliography, letters of support/endorsement, and letters of publication. Drafters can also benefit from a sample written proposal when creating this section, as it will provide an example of how the section should be organized and incorporated in the overall proposal. Writing a proposal is an extensive project, and sample proposals can be used to reduce pressure while providing the proper form needed for an excellent proposal. |
