CDN 3.0 Speeds up Web and Mobile Apps
CDN 1.0 sped up the delivery of content online, but we’re now speeding up web and mobile apps with CDN 2.0 and 3.0.
CDN 1.0 (Content Delivery Networks) sped up the static web.
Content Delivery Networks (CDNs) like Akamai and Limelight made the web faster by putting copies of photos, videos, and other large website files on servers around the world. By putting this content closer to users, the CDN sped up the download of content for people around the world.
CDN 2.0 is for Web 2.0 - the dynamic web.
We now run apps over the web, and accelerating static web pages is no longer enough. CDN 2.0 puts copies of the application on servers around the world connected via private and public networks so web apps run faster around the world. For example, Concentric CDN powered by Limelight uses both the Internet and a global private network, so data running between servers can hop-on our optimized private network in real-time if the Internet gets too congested.
CDN 3.0 is for mobile apps and the mobile web.
Especially on mobile, the bottleneck of content delivery has always been the “last mile”, the last bit of network (wired or wireless) connectivity between the CDN data center and the browsers on people’s devices.
CDN 3.0 optimizes the way a web page is painted. Concentric’s brand of CDN 3.0 is called Front End Accleration (FEA). FEA optimizes how data is sent from the edge server to the browser, so that the most important elements render faster.
