Modern websites are complex. A standard site requires 80 files served from 13 different domains. This needs a regular browser numerous round trips, and adds seconds to page loading time.
Amazon Silk is different in a radical new way. If you use Silk, without considering it or doing anything explicit, you’re calling on the computing speed and power with the Amazon Web Services cloud (AWS). We’ve refactored and rebuilt the browser software stack to push items of the computation in the AWS cloud. Allowing Silk do more work, quicker, and immediately. We label this “split browser” architecture.
Silk browser software resides both on Kindle Fire as well as on the massive server fleet that comprises the Amazon Elastic Compute Cloud (Amazon EC2). With each page request, Silk dynamically determines a division of training between the mobile hardware and Amazon EC2 (i.e. which browser sub-components run where) that can into account factors such as network conditions, page complexity and also the location of the cached content.
