What is CDN and Why You Need it for Your WordPress Blog
What is CDN?
Content Network Delivery(CDN) is a system of distributed servers that delivers web pages, images, JavaScript etc. It caches your website content and delivers to the viewers from their nearest Region.
When a visitor views your website, he instantly got redirected to the main web host’s server(i recommend siteground) and then he can see your website pages, images etc. This is good. But if your site getting high traffic, then there is a highly chance of website crashing. It is nightmare to the site owner and he may lose his customers or viewers. So here comes CDN, the powerful network of servers which are spread through the world. Using CDN, your static content is cached and stored on all of these servers.
Suppose If your main server is hosted in amsterdam,UK and a visitor from India, ASIA tries to access it, he will be redirected to his closest server which may be in Singapore.
