What is a CDN?
A CDN doesn’t actually host the web content but it does help in caching content at the network edge which helps in improving the website performance i.e. accelerate the response time or web page loading time.
Benefits of CDN
1. Improved performance and lower latency
According to a Google web performance engineer, Ilya Grigorik,
“Using a CDN allows us to terminate the connection close to the user, which can significantly reduce the cost of TCP and TLS handshake. For best results, you should be using a CDN to serve both static and dynamic content.”
2. Traditional web hosting solutions aren’t enough
The traditional web hosting methods are not enough anymore and a CDN network made up of several edge servers deployed in various geographical locations now play a very important role and surpasses the computing resources of traditional web hosting and delivers the high-quality and rich multimedia content in cost-effective and reliable way.
3. SEO advantages
In 2010, Google announced that the website would begin to affect the search engine rankings. So, the faster websites have better chances of higher SERPs. So, by using CDNs, you can improve your website performance and thus get a higher number in Google rankings.
CDN’s architecture provides reliability because if any point of presence (PoP) is down, the request is routed to the next closest / best point of presence available. It enables redundancy and ensures a pleasant web experience for users.
5. Simple integrations
CDN integrations and deployment is very easy and it only takes a few minutes to implement a CDN. CDN can be integrated with almost all kinds of framework, such as WordPress, Joomla, Drupal, or even with Laravel or Zend Framework.
