What
is CDN and why It is Important?
CDN stands for Content Delivery Network which
generally focused on various aspects to increase performance and speed of your
site, plugins and your all every content on your blog page.
CDN generally based on distributed computing which means having large
distributed system of servers around the globe which stores a copy of your site
into its servers. Instead of loading your site from one main servers it gets
load from any of the nearby server of CDN.
The goal of a CDN is to serve
the content to end-users with high availability and high performance that's why
I prefer to use a good CDN's server. It can hold any type of data you want to
provide to the end-user like videos, photos etc.
So it is very important enough
to increase your site speed very much in which free CDN services will
help you out. In addition, CDN's providers provide a degree of protection from
variety of attacks like DoS attacks by using their large distributed servers to
absorb the attack traffic.
Today CDN's are using in a very
good Hybrid model of P2P technology while the most early CDNs served content
use a dedicated servers owned and operated by the CDN.It is also very useful
for your blog which has over thousands of monthly visitors which not only
decrease your blog speed but also increase bounce rate of your site.
