What is Load-balancing and Do I Need It? - Conclusion
(Page 6 of 6 )
That covers the basics about load-balancing: what it is, how it works, and why you would want or need it. There are many resources available on the Internet that can go into more the intricate details of hardware and software solutions.
In addition, the rules for load-balancing may change, depending on exactly what it is you are trying to balance. Our discussion here has focused on the assumption that you will be balancing the load across several web servers. But if we had chosen to load balance servers with other tasks, like a mail server or database server, there are many other considerations that must be taken into account. Not all applications are able to be load-balanced, and this will need to be researched on a case-by-case basis.
Deciding on a load-balancing solution for your website can be a very important decision to your site’s continued success. Be sure to analyze your requirements, and make the best decision to fit your website’s current needs, as well as those into the near future. There is nothing more frustrating than setting up a complete system to ensure the availability of your website, and then having to re-engineering your load-balancing architecture after only a few months, which can be both a disappointing AND expensive proposition.
It is my hope that this article has equipped you with the general information you need to assist you in making an informed decision on when you actually need a load-balancing solution and how best to apply a load-balancing solution to your website.
