A content delivery network (CDN) is a system of distributed servers that deliver web content to users based on their location. CDNs work by copying website content to multiple servers located around the world. When a user requests a page, the request is redirected to the closest server to improve page load times. Businesses use CDNs to accelerate load times and reduce bandwidth usage globally. The main benefits of CDNs are improved performance, availability of content, security against attacks, and providing intelligence about users.

2. CDN - CONTENT DELIVERY NETWORK
 CDN is short for content delivery network. A
content delivery network (CDN) is a system of
distributed servers (network) that deliver pages
and other web content to a user, based on the
geographic locations of the user, the origin of
the webpage and the content delivery server.

3. HOW CDNS WORK
 Servers nearest to the website visitor respond to the request.
The content delivery network copies the pages of a website to a
network of servers that are dispersed at geographically different
locations, caching the contents of the page. When a user
requests a webpage that is part of a content delivery network,
the CDN will redirect the request from the originating site's
server to a server in the CDN that is closest to the user and
deliver the cached content. CDNs will also communicate with
the originating server to deliver any content that has not been
previously cached.

4. BUSINESSES USE CDNS
 When delivering large scale websites to a
global audience, CDNs can reduce latency,
accelerate site load times, reduce bandwidth
consumption secure applications and even
block data scrappers and other forms of
spammers hitting your server.
 Content delivery networks are used for B2B
interactions and in serving content to
consumers. Today, as more aspects of daily life
move online, organizations use content
delivery network to accelerate static content,
dynamic content, mobile content, e-
commerce transactions, video, voice, games
and so on.

5. 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.

6. 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. This content is not simply
limited to website content alone; it can also
comprise 4K and HD-quality video, audio
streams, apps, games and OS updates. With
website visitor attention spans growing shorter
by the day, it is imperative to deliver this
content as quickly as possible.

7. WHAT ARE THE BENEFITS OF A CDN?
 CDNs carry a significant portion of the world’s Internet traffic. They
are ubiquitous in presence and mitigate the toughest challenges of
delivering content over the Internet. But why are CDNs so
pervasive? Why is it that everyone, from small and medium
content providers, to the world’s large corporations rely on CDNs
to provide a seamless web experience to their end users?
 CDNs became an essential tool to successfully conduct business
online for one main reason: the Internet was not originally
architected to do all of the amazing things that it does today! It
simply wasn’t built to handle the demands of massive amount of
data, live high definition video, flash sales, and large downloads
that people expect today. CDNs were specifically built to make the
Internet work better, deliver media at scale, and to enable all of the
connected experiences you can imagine.

8. PERFORMANCE
What does performance mean? It means connected content delivered
at speed. It’s the difference between a click giving you immediate
access to new content, and a click then a 7 second wait while a page
loads or a video buffers.

9. AVAILABILITY
 Availability means that content remains
accessible to end users under high-stress
situations such as excessive user traffic,
intermittent spikes, and potential server
outages.

10. SECURITY
As the volume of high-value data and
transactions on the Internet continues
to grow, so do the forces of attackers
looking to exploit it – and these forces
are costing organizations big money.
According to a report by the
Ponemon Institute of Cyber Crime, in
2015 businesses around the world
suffered average losses of $7.7 million
due to cybercrime. Along with crimes
committed by malicious insiders,
DDoS and web-based attacks were
found to be the costliest.

11. INTELLIGENCE
As carriers of nearly half of the world’s Internet traffic, CDN providers
generate vast amounts of data about end user connectivity, device
types, and browsing experiences across the globe. They can expose
this data to their customers, thus giving them critical, actionable
insights, and intelligence into their user base. In the case of Akamai,
this includes Real-User Monitoring and Media Analytics to measure
end-user engagement with web content, and Cloud Security
Intelligence to keep track of online threats.
