Benefits of Using Content Delivery Network
When you do online business, you need a unique and well designed web resource to trade and purchase things and services online. You may use either an eCommerce website or an online store for this purpose. While planning to become an online merchant, it’s vital to understand what you actually need to become a successful one. For instance, you need a speedy site or store. To get a decent web performance and get rid of such problems as poor bandwidth, package loss and latency, try your hand with CDN.
So what is CDN and what benefits does it have?
Why is CDN in a Trend?
CDN or Content Delivery Network is a network of servers distributed around the world to provide faster delivery, and highly available content. The inside architecture of most CDNs includes a number of key components:
- Delivery nodes – these are caches running one or more delivery applications to supply a quick data delivery to consumers. They tend to be deployed as close to the edge as possible;
- Storage nodes – they provide data to caches or may be used for content pre-publishing;
- Origin nodes – these are the main sources for content. They are deployed within the operator’s network or a content owner’s infrastructure;
- Control nodes – it’s meant to host the management, routing and monitoring components of a CDN.
The main CDN benefits include reducing bandwidth costs, enhancing the global availability of the content and improving page load times. The number of nodes and servers, making a CDN may vary depending on the architecture. In some cases, it may reach up to thousands of nodes with ten thousand of servers on many remote points of presence (POPs). There are also some CDNs that build a global network with a small number of geographical POPs
Why is CDN Useful?
Using CDN is quite beneficial. Firstly, you’re able to get a real opportunity to speed up your website. Your final user won’t have to reach your own server to get access to your content with CDN any more. As your files, images and scripts will be copied and placed on servers in various POPs, the final user will get information directly from these servers. This option is able to speed up the load time drastically.
Thanks to CDN, your server won’t be overloaded. The Content Delivery Network is able to distribute and balance the load on your server and make it focus on general and dynamic content.
CDN storage is able to reduce expenses on using foreign hosts and reduce server’s bandwidth consumption.
In addition, your website will be protected from spammers, scrapers and other bots while you apply for CDN as it’s able to protect your content from DDoS attacks.
