Thanks a lot. You use the most basic way to tell us what CDN is.

Excellent video thanks. I appreciate the mention of dns vs anycast implementation and the ddos advantage anycast has.

thanks a mill for this content! very easy to understand, especially for someone who had no idea about what CDN is and is now working with it

Very happy to learn about the CDN auto-minification of js files! Now we can remove minification on our local & build servers to get quicker development feedback loops (and not burn cpu for no good reason), and still have the benefit of the CDN doing minification :D

Great content always. This channel will hit 1 million very soon

Amazing job and totally agree with that not a second is wasted with these high-information quick videos. One quick question, could you clarify the TLS conversion part?

So the client to VPN uses TLS but then how does the CDN communicate in an encrypted but more performant way to the central servers? AFAIK TLS is an encrypted tcp communication. Is there a more performant encryption layer used between CDNs and the origin servers?

Good teacher with a good voice for it!

Great Video! Do you create all of the vector graphics yourself in illustrator? Must be a lot of work for each video!

1. CDN can provide protection for DDos attaction.
2. CDN has high availability.
3. CDN can reply to user’s requestion from the nearest PoP.

I believe persistent connections can be used to reduce the latency between the EDGE servers and origin server in case of cache miss. SSL termination is definitely another plus in case the persistent connection is expired.
