What is a CDN? (Content Delivery Network)

Показать описание

A CDN, or Content Delivery Network, is an important tool for anyone who runs a website. It can not only increase the speed of your website, but also increase security with a WAF (web application firewall) and protect against DDOS attacks.

I now understand CDN. Another video I was watching confused me, but yours was easy to understand.

For example, Youtube uses a CDN so you can watch these videos!

CDN is used everywhere, even in streaming. In principle, no site can do without it, especially YouTube. I highly recommended CDN from G-core labs.

Super clear Video, perhaps too close for comfort.

CDN is an irreplaceable thing. We have been working with G-core labs for more than 2 years. Amazing performance, SEO without them is simply impossible.

CDNs are supposed to pass the data that they receive from their clients to various data centers so that it remains in reach of the audience.
In order to make the content available to users in the most efficient way, CDNs work by using server optimizations which is based on the type of content.

Anyways, read the below. This might help.

If you find a webpage or a video that technically explains how a CDN works please let me know. This video like others is not it.

Interesting video, however there are a few things that you left out when talking about the benefits. The fact that CDN's are able to analyze in and outgoing traffic to check for malicious activity requires them to be able to decryspt your traffic. So in theory if you established a secure connection to a server a MITM should not be able to peek into your traffic. But CDN's are able to do that because as far as I know they have your private key stored on their servers to be able to decrypt and analyze your traffic. Correct me if I am wrong. But that's probably also one of the reasons why CDN's are insanely high secured.

Hey Thio,

Do big websites like Facebook, Youtube, Twitter etc. have CDNs? Or if they ever get DDoSed they can withstand them? Or they have a CDN but you can't see it? This is a really interesting topic and I would like to hear more about this :)
