I believe there is a variation to Gaurav's understanding on open-connect caching mechanism. A new uploaded video DOES NOT goes directly to the caching server, instead they are resolved to a 'a small Netflix DB replica" in that region, which in-term populates the caching layer for new videos or most frequently accessed videos. The distinction is important because otherwise the design is assumed to directly populate OC CDNs, which is not the case. So for example, if a viewer in Australia wants to stream a non-cached US content: Instead of directing all the Netflix traffic through under-sea cables, Netflix copies the video file (transcoded) from US-based storage to a storage location in Australia once during off-peak hours. Once the video has reached the continent, it’s copied to all the Open Connect servers present in the ISP networks. This is not to point out a flaw in the video, just a clarification.

Another informative video from you. Nice explanation. Thanks. Just wanted to add something on the caching part. Many websites take help of CDN providers like Akamai to do the caching on behalf of them. The CDN providers have the required infrastructure across the globe wherein they have placed their caching servers in most of the countries.

Hey Gaurav, I was just wondering how the Open Connect or KZread Red boxes are any different from the long existing concept of CDN (Content Delivery Network). The only change is, being big companies they have the money and resources to create their own personal CDNs and brand them which is kind of building your own house instead of renting one. Is there something I am missing here ?

@gkcs

I was having the same question as how these Oppen connect boxes are different from CDNs.

that's pretty interesting concept... very well explained 👏👏.....

Can you explain some of the advanced concepts of video streaming too? For eg., Bandersnatch? I wonder how Netflix is providing conditional streaming of video chunks based on user selection.

I just love your system design videos.

That's a improper system design for KZread, probably slow.

Yes Content Delivery Network plays a really important role if the geographic location of physical server is far and also I think what these OTTs would be doing is what we are getting in recommendation might be based on geo location rather than your watch history , this way if one guy from ur location has seen some movie it gets cached to a CDN and then when u request for the same content , since it comes in ur recommendation its extremely fast

Very nice explained and made it interesting. Will be waiting for more good system design question.

Software Architecture is the most important thing today. No matter how much you you improve on ML algos or buy hardware etc... It is the archtecture that defines quality and reliability. How you connect components together using a good deisgn tactic and make each component work flawlessly by the deisgn pattern matters the most. It is archtecture everywhere. The fact that you make videos on it is really a good thing. Developers today must understand the imporatnce of it. It is not just writing code but many other things too.You are doing a great job by making such videos.

Very informative!
