What is Content Distribution Network (CDN)?
A content distribution network—also known as a content delivery network—is a large, globally distributed network of specialized servers that accelerate the delivery of web content and rich media to internet-linked devices.
The primary technique that a CDN (content distribution network) utilizes to speed the delivery of web content to end users is edge caching that entails storing replicas of image, static text, audio, and video content on multiple servers around the “edges” of the internet, so that user requests can be followed by a nearby edge server rather than by a far-off origin server. To accelerate the delivery of dynamically generated Mobile web development content that’s difficult or impossible to cache, an advanced content distribution network uses a range of techniques such as route optimization, TCP connection optimization, and pre-fetching. CDN improves the security, performance and reliability of a website.
How CDN works?
To reduce the distance between website’s server and the visitors, a CDN saves a cached version of its content in multiple geographical areas (points of presence, or PoPs). Every PoP contains a plenty of caching servers responsible for content distribution to visitors within its proximity.
In essence, CDN puts content in many places at once, rendering superior coverage to users. For instance, when someone in London accesses a US-hosted website, it is done through a local UK PoP. This is much faster than having the visitor’s requests, and responses, travel the full breadth of the Atlantic and back. This is how a CDN works in a nutshell.

Benefits of Content Distribution Network in Mobile web development
A content distribution network handovers substantial benefits to web users, content and application owners, and network service providers:
For users: Users of websites and web applications delivered through a CDN experience faster page loads and quick transactions than they would in the absence of the CDN.
For content owners: For content and application owners such as e-commerce sites, media properties, and cloud computing companies, using a content distribution network to advance end users’ experience can lower abandonment rates, improve conversion rates, increase ad impressions, and strengthen customer loyalty. Practicing a CDN can also make an important contribution to web security, for example by helping to absorb and relieve a denial of service attack.
For network service providers: With the bursting growth of online streaming and other rich media services and higher user expectations about web performance over multiple device types, today’s network service providers are finding it essential to deploy their own content distribution networks. For network operators, deploying a CDN can lessen subscriber churn, facilitate the development of value-added services, decrease traffic on the core network, and facilitate operators to sell CDN services to enterprises and third-party content owners.
Today, business are dealing overseas and serving global clients. Depending on the region and hosted server content may take time in loading. CDN is one of the advanced technique which helps websites to deliver content faster. It’s also important to keep it mind while going for Mobile web development that your website should load content fast enough to hold your visitor on a website and decrease the bounce rate. Website loader is one the option to work on during Mobile Web development process to avoid slow content loading problem.
