Published 2014 by John Wiley & Sons, Inc. 1 Abstract view of a CDN. rather than serving each individual request directly from the content provider’s origin server. Nowadays, CDNs are a prerequisite for delivering quality online experience for live, linear, and on-demand delivery of website and media content. They often leverage cloud (compute and storage) infrastructure and services to provide scalability, resiliency, availability, and performance. The reason why a CDN may be used varies depending on the particular enterprise—providing live streaming coverage of major events, distributing training videos to employees, providing fast and efficient software downloads to customers, or enhancing the performance of an e-commerce website.

The user’s browser executes the script, and then displays the document, including any visible output from the script. JavaScript and ActionScript used for DHTML and Flash technologies are examples of client-side scripting. Server-side scripting refers to applications running on the edge server of a CDN to change the content on various Web pages. Such Web pages are often created with the help of server-side languages such as ASP, Perl, PHL, Ruby, and WebDNA. Server-side scripts are embedded into the HTML source code, which results in a client’s request to the website being handled by a script running on the edge server before it responds to the client’s request.

From a product perspective, a CDN provider can bundle content management, storage, and customer-onboarding (portal) services, in addition to the core CDN functionalities and value-added services (VAS). 3 shows an example product portfolio of a CDN, showing the five constituents. , caching, routing, delivery) are running the risk of being commoditized and sold mainly on price. Therefore, CDN providers are adding new services on top of their basic offering to generate revenue from running the business.
