Following are some of the top features of Rackspace CDN:
Powered by the Akamai content delivery network
Using the Akamai network, Rackspace employs a custom map of over 200 edge nodes across six continents. This map includes 77 North American locations; 36 European locations; 73 Asian, Middle Eastern and Oceania locations; and 15 South America locations.
Instant provisioning
The Rackspace CDN service can be turned on in seconds through the Rackspace Cloud Control Panel or via the REST API and language bindings. No professional services, ticket requests, or phone calls are needed to get your site up and running.
Multiple interface options
Rackspace CDN is fully supported via the Rackspace Cloud Control Panel. You can also interact with Rackspace CDN by using our REST API.
Whole site delivery and acceleration
Rackspace CDN does more than just accelerate individual objects in storage. Using origin-pull technology and DNS, you can identify your website and content origin, and the entire site, everything from images to style sheets, will be accelerated.
Origin protection
Keeping your origin safe during a malicious attack is vital to the health of your website or application. Rackspace CDN helps keep your website and applications safe by absorbing all edge requests, harmful or not. Because all requests are first served by the edge nodes, your origin won’t get the brunt force traffic associated with a DDOS attack. This means that your website can still serve good traffic while an attack is occurring, keeping your visitors engaged at all times.
Custom SSL
Serving content over HTTPS is quickly becoming standard for websites and applications. Rackspace CDN gives you multiple options for using your own domain while serving over HTTPS, including Subject Name Alternative (SAN) certificates and dedicated certificates.
Access controls to protect content
Rackspace CDN can help you control who sees your content by setting access rules that are enforced on the edge nodes. Access rules can be set by geography and referring domain, and they help prevent unwanted linking and traffic from non-strategic regions.
Multiple origins flexibility
Rackspace offers you a full portfolio of public, dedicated, and private managed cloud solutions for your workloads. Rackspace CDN can use any of these resources as origins, with the flexibility to use multiple origins with a single website or domain. You can even use Rackspace CDN with origins not hosted at Rackspace.
Dynamic visitor handling
Rackspace CDN delivers both static and dynamic content. Dynamic content that changes for every user or a set of users requires additional handling at the edge nodes. Rackspace CDN enables you to set a TTL of zero for non-cacheable content, and supports dynamic content handling features like cookies, header forwarding, and cross-origin resource sharing (CORS).
Keep your content up-to-date
Rackspace CDN supports content time to live (TTL) values in seconds, all the way down to zero. In addition, you can submit requests any time you need to update content outside of the TTL timeframe.
Granular control
Rackspace CDN enables you to implement edge rules based on resource path, meaning that your rules can apply to multiple levels of granularity, from the entire site to a specific file.
