Need Advice

  • Has anyone ever heard of content delivery network? It’s a service that replicates your blog onto different servers so that when a viewer tries to view your site, he is redirected to a server nearest him. Supposedly, it makes accessing the site faster. Isn’t this the same as caching? What if I update my blog, add a new page or post, do you think the CDN service picks that up instantly and updates the various copies or is it possible someone might end up viewing an old version of your site?

  • A CDN doesn’t hold the pages of your blog. Wlel, not under normal conditions. What it does is holds your external files like images, JavaScript, CSS, etc. It serves those from places closer to the user so that there’s less load on your main server which lets it run faster, and lets the images, etc download faster because they are closer to the user and on a different server.

    This is different to caching becaause caching creates static versions of your dynamic pages, but it’s all of the files are held on the same server.

    I think it is possible that someone might view an old version, but chances are slim. These update pretty quickly I would imagine. Even if you post a new blog post, it won’t be long before people see it.

    Someone can still cache and have CDN’s, because it will cache what is given. While the CDN is physically closer. This of course helps.

    Here is an excerpt from an article
    will periodically pull the files from the origin (that is your server). How often that is, depends on how you have configured headers (particularly the Expires header). It of course also depends on the software driving the CDN — there is no standard in this field.

    Thanks for the feedback. Does anyone actually use this service? Would you recommend it? Or would a regular shared server be just fine for a blog?

    It’s good if you’re site is slow and the server is the bottleneck. If you’re just starting out I’d say to not use it and see how your site goes. You’ll soon find out if it needs a CDN, caching or something more pretty quickly.
