Understanding the concept of Content Delivery Network (CDN).
                     UNDERSTANDIN
G THE CONCEPT 
OF CONTENT 
DELIVERY 
NETWORK (CDN)
WHAT IS A CDN?
 A CDN (Content Delivery 
Network) is a highly-
distributed platform of 
servers that helps 
minimize delays in loading 
web page content by 
reducing the physical 
distance between the 
server and the user. 
 This helps users around 
the world view the same 
high-quality content 
without slow loading times.

SIGNIFICANT 
TRAFFIC 
 Without a CDN, content 
origin servers must 
respond to every single 
end user request. 
 This results in significant 
traffic to the origin and 
subsequent load, thereby 
increasing the chances 
for origin failure if the 
traffic spikes are 
exceedingly high or if the 
load is persistent.

IMPROVES THE WEB 
EXPERIENCE
 By responding to end 
user requests in place of 
the origin and in closer 
physical and network 
proximity to the end user, 
a CDN offloads traffic 
from content servers and 
improves the web 
experience, thus 
benefiting both the 
content provider and its 
end users.

GOAL OF CDN
 The goal of the CDN is to 
reduce latency the delay 
between submitting a 
request for a web page 
and the web page fully 
loading on your device by 
reducing the physical 
distance that the request 
must travel.

HOW DOES A CDN 
WORK?
 CDNs store a cached 
version of your website 
content in multiple 
geographical locations 
around the world, which 
are known as “points of 
presence” (PoPs). 
 These PoPs will contain 
their own caching servers 
and will be responsible for 
delivering that content in 
the user’s location.

DELIVER AN 
INCREDIBLE 
VARIETY OF 
CONTENT
 CDNs deliver an 
incredible variety of 
content that includes: 4K 
and HD-quality video; 
audio streams; software 
downloads such as apps, 
games, and OS updates; 
data records that contain 
medical and financial 
information; and much 
more.

WHAT IS A CDN 
PROVIDER?
 A CDN provider is a 
vendor that provides 
businesses the ability to 
serve their content to 
end users across the 
world over a content 
delivery network. At 
Akamai, we take pride in 
being the world’s leading 
CDN provider.

WHY USE A CDN?
 CDNs offer an easy way 
to increase the speed of a 
website while also 
lowering the latency. 
Therefore, they are 
essential for the fast, 
efficient and secure 
delivery of content to 
users around the world.

CHALLENGES
 Content providers face 
challenges such as: 
delivery of different types 
of content, adjusting 
content for different 
device types (device 
detection), and securing 
data and the online 
presence of their end 
users.

BACKBONE OF THE 
INTERNET
 CDNs have formed the 
unseen backbone of the 
Internet delivering online 
content for retail, finance, 
healthcare, and other 
businesses to end users 
around the world with 
speed and at scale.
