Deliver content faster—and more reliably with a CDN Service

CDN Services can help you deliver content and applications to nearly any user or device. While a CDN solution can be a powerful enhancement to your enterprise network, it also integrates well with a variety of AT&T services.

Accelerate content with the power of a CDN Solution.

Content is a key business driver. Using it effectively means delivering it when and how customers want it. AT&T CDN Service is a multi-faceted, easy-to-implement solution that accelerates the delivery of your digital assets in a variety of ways:

Front-end optimization

As websites have grown in complexity, so has the task of keeping them fast and responsive. AT&T CDN caches hundreds of smaller, static assets (like images, CSS and JavaScript files) in the edge server nearest to a customer, so a user spends less time waiting to access a page.

Mobile optimization

A CDN can optimize web experiences on smartphones and tablets. By detecting software and network information about a user’s device, it can send the version of an image (or any digital asset) that best matches that device—all without sacrificing quality.

Dynamic Web and Content Acceleration

Edge servers can boost the performance of pages with dynamic content—like shopping carts, catalogs and user account portals—by temporarily caching it closer to a customer. As a user navigates the website, the CDN enables content specific to that customer to load faster.

Deliver secure web experiences customers can count on.

Creating positive customer experiences online is about more than delivering content quickly—it’s also about keeping it accessible. CDN services provide strong, security protocols that can help your enterprise defend against DDoS attacks and other web-based threats.

Increase network scalability with less capital investment.

Web traffic can vary greatly. Making sure your site can keep pace is essential. A CDN solution can temporarily scale up its caching rules to offload more content from your origin servers to the CDN edge. It enables your site to respond quickly, without spending additional capital on expanding your internal network.
