What is a CDN?
A Content Delivery Network, popularly known as CDN, is a distributed network of servers globally located to store replicated content that enables businesses to access content quickly and effortlessly. A CDN is a highly available and effortless platform for faster content delivery. The replicated content can be accessed from multiple locations concurrently, and therefore it facilitates an uninterrupted, flawless business operation.
CDN aims at enhancing the overall user experience and delivering improved business services more efficiently by optimally utilising the network resources. Content provider companies like media houses, content creation companies and e-commerce vendors approach CDN operators for getting their content delivered to their audience or end users. A CDN service can be availed from CDN service providers that offer server hosting in their data centres and provide content services.
What does CDN architecture constitute?
A typical CDN architecture comprises:
- Delivery Nodes: Delivery nodes are meant to deliver the data to the end users. Every delivery node contains a cache deployed on the nearest edge to the user on the delivery applications.
- Storage Nodes: The storage nodes provide the data to the cache. These nodes facilitate tiered caching and protect the origin servers; they are deployed in a hierarchical model. The storage nodes help in pre-publishing the content.
- Origin Nodes: These nodes are deployed within the infrastructure of the content owner or the network of the operator and are the primary content resource. Multiple origin nodes can be utilised for enhanced resilience and scalability.
- Control Nodes: The control nodes manage, route and monitor various CDN components. It enables the integration of OSS/BSS systems with the configured Network Operations Centres.
Deployment of the CDN nodes in multiple locations helps in lowering the costs associated with the bandwidth, as well as reducing the page load time and boosting the availability of content across the globe.
A Content Delivery Network may consist of hundreds or thousands of servers and nodes based on the CDN architecture and remote Points of Presence (PoPs).
How does a CDN enhance business performance?
CDN offers a range of benefits and capabilities to help companies that witness voluminous website traffic. The CDN serves the web content and allows seamless and quick access to online content.
Major CDN features that accelerate business performance include:
- Reduced Server Load
The CDN spreads the content across the network by strategically placing the web servers and forming a network infrastructure. This not only adds to the capacity to serve the users but also enables companies to serve more customers concurrently. As the content is scattered over various nodes, the server load is drastically reduced.
- Faster Content Delivery
The content delivery networks are more reliable and allow operators to render rich content with improved service quality while lowering the server loads, thereby reducing the costs. Moreover, the web application cache in the browser prevents downloading a specific page that has been accessed through the same browser in the past, which saves the page load time as well.
- Easy Segmentation of Users
CDNs are highly capable of identifying and analysing user interests from their browser history and help enterprises segment their website audience based on the content accessed by them previously.
- Reduced Network Latency and Data Loss
The improved stream quality rendered by a CDN helps to reduce the jitters during content delivery. Enterprises can effortlessly deliver high-definition content at reduced costs and decreased network loads by adopting an effective CDN.
- High Availability
With the fallback and edge servers in place, the content assets are dynamically distributed to provide improved asset delivery control. The capacity to address each customer’s requirement can be optimised, real-time view of the load and statistics can be generated, active regions can be identified and accurate viewing details can be reported to the customers. CDNs are embraced to offer 100% availability despite frequent power interruptions and hardware or network outages.
- Storage and Security
Maximum security to content storage and capacity, including videos and graphics content, archiving and data backup services are the key feature of the CDNs. CDN prevents the content from being compromised through Digital Rights Management and authenticated access to the content.
CDN services are core essentials for businesses of all types, specifically, the media-focused and content-centric companies. Effortless, prompt and uninterrupted content delivery enhances user engagement and can transform them into potential business opportunities. Improved customer experience induces loyalty and coaxes them to recommend the products and services to other prospective users.
