CDN

Cloudfront can be simply defined as a CDN (Content Delivery Network), caching your static assets in a datacenter nearer to your viewers. But Cloudfront is a lot more complex and versatile than this simple definition. Cloudfront is a “pull” CDN, which means that you don’t push your content to the CDN. The content is pulled into the CDN Edge from the origin at the first request of any piece of content.

You built a new web application, you are serving it using Cloudfront, but you want that only members from your organization can view the pre-release version.

The tech B2B world has changed in the last decade. It used to be sales talks to sales and agree on a product and price. Then give the job to the tech team. In a tech-startup, Geeks are King. They decide what’s useful or usable. If you can’t convince the geek, you won’t get the business. At Spuul, I am on geek-side of the chain, and too often I had to experience the lack of market knowledge from some corporations.

You can highly improve your site display speed by using a CDN. This is also true with Koken. Koken doesn’t provide a “out of the box” way to handle CDN, so I wrote a plugin to allow you to serve your Koken assets through edges closer to your visitors.

While writing about Cloudfront, I came accross another CDN service called Cloudflare. The free entry price made me suspicious, hosting and transport has a price. Since I had nothing to loose and that this domain was new, I decided to give it a try. So far, didn’t find any dirty trick. What is Cloudflare? CDN is one of the features, but in fact, they do more than just delivery. Content Delivery Network They place themselves in the CDN category.
