Load Balancing – Hardware Changes That Can Make the Difference
Load balancing is all about hardware expansion because it’s only a matter of time until you will need more than one server for your website. If you make a blueprint of exactly what you need to do or at least make some advanced planning strategies, you’ll find that there is a lot you can do to optimize the performance of your hardware. Simply having one dedicated server to handle an incredibly large workload isn’t enough. There could be surges in traffic or bandwidth requirements that would overload the server. Thinking in advance about what could possibly go wrong will keep your high traffic website safe from the perils of extreme resource requirements.
Among these, an overload of system resource demands can cause a server to malfunction, forcing it to operate at temperatures that are unsustainable in the long term. You should look at what makes hardware perform at its best, which configurations will benefit the overall performance and keeps your site running at optimal levels. In order to give you a better understanding, this article will present a mock scenario that explains the process of load balancing and what it really is.
A business is launched on the Internet. In order to accommodate the online business website, a server is purchased and set into active status. Initially, the business does very well, performing at more than acceptable rates of content delivery, access times and overall performance levels. This is because the initial load on the server is relatively low. As a year goes by, the business becomes increasingly popular, requiring more and more of the current resource levels to be used at all times. After a year and a half, the business reaches “point break”. It can no longer handle the growing influx of customers and the server shut down. This forces the online business to make some pretty complex business decisions. In order to accommodate the growing number of customers and keep their site online, the business opts to create a “server farm”. A server farm is a group of servers that is designed to grow in accordance with resource demand.
Adding a server every time the demand escalates as a collective whole will help the company to stay online at all times and never have to worry about whether or not there are enough resources at its disposal. In order to ascertain whether or not an additional server is needed, a company must gather the resource demand statistics from their website. This can be done through the control panel, in the administrative portion of the software side of server management.
These statistics give the business owners used in our example the raw data they need to decide whether or not adding another server is beneficial and worth the additional cost. When managing high traffic sites on the Internet, servers are everything. Unless you have a college education and certification in the areas of how algorithms used in computing will affect how a server performs, you’re not going to get very far. The internal mechanics of load balancing is usually reserved for technicians and people with a college certification in the area of computer sciences.
Your average business owner is not going to be able to engage in the tweaking and performance areas of the software codes. They can, however, take part in the addition of multiple servers to handle the additional resource demand. Load balancing is pretty simple to perform if you have enough money and the server farms you can build are both economical and an intelligent way of expanding your business.
Making sure your business is able to handle its own popularity is a matter of planning ahead. If a business plans on launching an advertising campaign that is sure to bring a large number of new customers, then adding servers to the “server farm” before the launching of the advertising campaign would be an example of effective load balancing. If the business has an advertising schematic that causes their customer base to grow gradually, then using the raw data accessible from the control panel would be a fantastic idea. Using graphs and charts, gauging how the business is growing and the expectation for increased server demand will prepare the business for the changes to come. Armed with this knowledge, adding servers in accordance with a predictable and gradual increase in demand would be optimal.
In a nutshell, load balancing comes down to thinking ahead, using resources to effectively manage and expand the amount of hardware used to deliver Web content to the masses and staying focused on the financial bottom line.
