The other day I wrote a post, “What Is A CDN?” where I explained what exactly a CDN (Content Delivery Network) is, how it works, and what it does. I’d like to elaborate a bit on the post and go into a few of the things you can do with a CDN, how it could be beneficial to your site (large or small), and how you can do it for a relatively low price.
There are typically a few different types of Zones you can configure with a CDN – push, pull, vod, and live (still relatively new).
Push Zones are built for larger files that rarely change. The data is uploaded to a storage array which is then automatically pushed to all of the servers in the CDN. The files remain until modified or the zone is deleted. (e.g. PDF’s, Installers, E-Books)
In a recent video interview with Google’s Matt Cutt’s, he hints that Google is considering using a site’s speed as part of the algorithm that ranks the order of pages in its search results. To break it down quite simply, fast sites might rank higher, while slower-loading sites might suffer in the results. Of course, that is only the case with no other part of the algorithm in effect. Google’s PageRank algorithm is very complex and includes many factors and variables. By adding loading speed into the algorithm, it will not completely alter the results. Obviously, the point of this would be to improve search quality even further by allowing users to access information faster outside of Google search results.
“…A lot of people within Google think that the web should be fast, it should be a good experience; and so it’s sort of fair to say if you’re a fast site, maybe you should get a little bit of a bonus. Or maybe if you have a really awfully slow site, users don’t want that as much.”, says Cutt’s in the interview with WebProNews. While I have talked about page loading times in the past and why they are important, this new proposal only renforces the idea.
