Content delivery network from edgecast cdn is a system of distributed servers that delivers web content and web pages basing on the geographical location of the users and the source of the content delivery server. This service is efficient in speeding content delivery of sites with high global traffic. The closer the Content Delivery Network server is to the user, the faster the content will get to him. It also offers protection against large traffic surges. Servers that are near the website visitor are the ones that will respond to the request. 

The content delivery network copies the website pages to a network of servers that are found at different geographical locations, caching the page contents. When users place requests for the web pages that are part of a CDN, the content delivery network redirects the request from the originating server to the server in the CDN which is close to the users and delivers cached content. It will also communicate with the server at the origin to provide content that was not in the cache. 

How do you know that you are on a CDN server?

The procedure of bouncing through the content delivery network is almost transparent to the user. The only way you can realize if people have accessed the CDN is if the URL delivered is different from the requested URL. CDNs are vital for serving content to customers and B2B interactions. Nowadays, as more aspects of life go online, companies use content delivery networks to accelerate mobile content, video, voice, games, dynamic content, and static content. 

CDN caches static web content at strategic locations to give maximum throughput for delivering the content to the users from the nearest server. It also gives developers a global solution that provides high bandwidth content by caching content at the global physical nodes. 

Benefits of the CDN to users

The benefits of caching a website using CDN assets include providing better performance and a good experience to the users, especially when they are using applications that require multiple round-trips to load content. They also do great scaling to handle the instantaneous high load in a better way, like starting to launch a product at an event. It also distributes the requests of the users and serves them content from edge servers; thus sending less traffic to the origin server. 

When a user visits a site that does not use CDN, the browser downloads all referenced assets from all origin servers. If the origin is in Japan and the user in New York, all assets will be downloaded from across the world to all content delivery networks. I such cases, users will experience long page load times due to high latency. When you cache your content on the CDN, the content gets closer to people from different locations, thereby improving the time used to load the pages. 

After caching your static content on the CDN, developers can port their content through the content delivery network to bypass congested internet service providers. They will distribute files to servers around the globe, thus reducing the amount of time you need to access the data. Some developers use libraries like Twitter Bootstrap to improve their functionality and layout. However, developers might decide to host their files on CDN to improve performance and save on bandwidth. 


Computer delivery networks are a populous way to distribute traffic; making web applications and requests to run faster. With this solution in production, the users will be able to download content locally from third party servers instead of the remote placed origin servers. It not only increases performance but also reduces the companies’ requirement to build and maintain a global network. When it comes to delivering the actual user experience and web service, developers can rely on CDNs to take the responsibility brunt.
