By now, you may have heard about the benefits of a content delivery network (CDN) or an application delivery network (ADN), and wondered what all the commotion was about. After all, the content delivery network market is estimated to grow from $3.71 billion in 2014 to $12.16 billion by 2019. However, before you pursue any one solution, it’s essential that you can answer this question: What’s the difference between an application delivery network and a content delivery network? In the most general sense, CDNs optimize static content while ADNs are typically responsible for web acceleration of dynamic content. Each solution is designed to accelerate the web experience while reducing load times. The points in this presentation target specific areas to consider throughout your delivery network research process. After reading, you might be able to better help the CDN and/or ADN provider you choose diagnose your site’s maladies and propose an optimal solution to improve performance.

What’s the Difference between an Application Delivery
Network and a Content Delivery Network?

2. Static or Dynamic Content
If your site primarily features static content, a CDN is your “go-to” delivery network.

3. Static or Dynamic Content
If your sites features dynamic content, an ADN or web acceleration add-on to a CDN
is a good option.

4. Web Traffic Patterns
CDNs are ideal for sites that have to connect users that are far from the hosting
server. Any company who is looking to reduce load time should consider using a
CDN. Global brands with a heavy ecommerce presence are prime candidates, as
holiday shopping traffic spikes can put significant stress on the website.
For example, Target crashed twice in six
weeks in 2011 shopping and back-to-
school surge. Retail Online Generation
reported, “…for every 1,000 electronics
shoppers that experience three errors,
the cost to the site is nearly $100,000.
Target’s website averages 1.3 million
visitors a day this time of year, therefore it
presented repeated errors to over 1.2
million consumers on Sept. 13. You can
start to get a sense of how that adds up.”

5. Enterprise-level CDNs are equipped to handle as much or as little traffic as is
thrown at them, even at Target’s scale (and others). They use Points of Presence
(PoPs) or edge caches to mirror the static content at the server origin and reflect it
to a closer end user. Bringing the data closer reduces network latency, which is
one aspect of poor site performance.
ADNs, on the other hand, are primarily implemented to work with dynamic
content or content that’s generated on the fly (online gaming, online trading, etc.)
To speed up end-user delivery, an ADN reduces server latency by distributing the
data load evenly across multiple servers. This reduces the possibility of any one
server getting overloaded.
GolfWeek utilized the CDNetworks video acceleration service for robust video
delivery and integrated reporting for its international presence. This option
worked for them because it meshed the strengths of both CDN and ADN services,
and provided the customer support GolfWeek desired to lead the way.

6. Location of End Users
Both CDNs and ADNs address the latency issues that slow down loading time. If 1)
your site has, or is aiming for a global presence; and 2) it features rich dynamic
content; a combination CDN with ADN acceleration will generate the fastest
response times and the best global security.

7. As mentioned with GolfWeek, combining the powers of CDNs with their ADN
dynamic content acceleration can ensure that users get a quality experience every
time they visit a site, no matter where in the world they call home. Shopify
boosted user experience globally to ensure they could compete in growing
markets. They put it best: “With CDNetworks local points of presence, our
Australia-based merchants get the same performance as in North America.
Neither Shopify nor our customers have to invest in datacenters or co-hosting.”
Above all, it’s important to choose your CDN/ADN provider based on the extent of
their (global) resources as well as how able and willing they are to work to
develop specific goals. Your site performance and content acceleration depends
on it, as well as help with the answer to “What does my site really need?” Keep
this in mind while deciding which route to take.
