According to Wikipedia,
A content delivery network or content distribution network (CDN) is a geographically distributed network of proxy servers and their data centers. The goal is to provide high availability and high performance by distributing the service spatially relative to end-users. CDNs serve a large portion of the Internet content today, including web objects (text, graphics and scripts), downloadable objects (media files, software, documents), applications (e-commerce, portals), live streaming media, on-demand streaming media, and social media sites.
Amazon CloudFront is a web service that speeds up distribution of static and dynamic web content, such as .html, .css, .js, and image files, to users. It is optimized for speed, performance and scalability. The user is in control of the service and can make changes on the fly. It includes real time reporting so can be monitored for the performance. It has been enhanced for static and dynamic objects and video delivery.
Statistics
Today, 50% volume of content used over the internet, globally, is served by CDNs. Thus, proportion of the internet traffic served by CDNs is expected to grow more than 60% by 2020. The global content delivery network market magnitude is expected to grow from USD 12.3 billion in 2019 to USD 22.1 billion by 2024, at a CAGR of 12.3% from 2019 to 2024.
Challenges
Building the largest, highest-capacity, most innovative CDNs have a lot of challenges. The five most common content delivery challenges include:
1. Geographical issues
2. Scalability
3. Content Security
4. Stable Performance
5. Delivery to any device
Architecture
Amazon CloudFront service is valuable for companies with a requirement for higher response times and large file content that want to dispense these files to a sizeable number of users. Once content is put in an origin server, like an Amazon Simple Storage Service bucket or an Elastic Compute Cloud instance, it’s injected out to multiple CloudFront servers as content is demanded.
Prices
Amazon Cloudfront does not charge a flat fee for all CDN traffic. Customers are charged pay-as-you-go (PAYG), and prices differ per region and traffic type:
• Data Transfer Out to Internet (per GB)
• Data Transfer Out to Origin (per GB)
• HTTP and HTTPS Requests (per 10,000)
On-demand prices differ per edge server region.
