CDN (Content Delivery Network) - AWS CloudFront

Firstly start with CDN -
CDN stands for content delivery network. It is used to deliver different type of data to end users like images,videos,applications and APIs. When you see a dynamic images using adobe flash on website. That's the use of CDN. It just stores the cached copy of contents and delivers it to end users for better speed.

How it works?
A CDN uses a network of servers in geographically dispersed locations(edge locations) to cache copies of content close to end user, lowering latency when thay download or stream the objects.
When a specific page, file, or program is required by a user ,the server dynamically selected to deliver the content is based on closest network proximity or the one with the fewest network hops to the end user.
Content is replicated across edge locations thereby providing redundancy.

 CDN Benefits
Improves customer experiance with faster page loads - bounce rates go down and customers stay on your site longer .
SEO benefits: site speed and load times are important to search engine ranking.
 A study by Google showed that every 1/2 sec of page load time dropped customer traffic by 20%. Google factors in page load times in their quality score.



You can use CDN for dynamic content like News, Weather, Sports, Social media, Advertising, Travel.

It reduces latency. Many cloud service provider companies provides this service like Akamai , AWS CloudFront .
