[@anirbanhaldar7081]

Wow.. after watching Dukaan podcast .. I was having some doubt how their failover is happening.. good to see thats covered here in detail ❤

[@koteshwarraomaripudi1080]

Great initiative to go through a white paper and explaining us. Keep the content coming. Thanks a lot. Hoping to see more of these discussions on Distributed systems/DB papers

Mai bhi yahi sochta hu 😅 nahi dekhna logo ko deep tech. Motivation and roadmap dedo bas.

@@AsliEngineering That is unfortunately the case. In general a very common topics(even c/c++ despite having tons of videos) get lot of views.

Thanks for great explanation

[@nishantnasa8798]

Thanks, I was interested in this as well after watching Dukaan podcast. Can you share what tools you use for video creation? I am interested in sharing some tech content myself & have been inspired from your journey. Also one appreciation that you zoom in on diagrams during explanation, that's really helpful for me as I have low vision so keep doing that too.

could you cover multicast and compare with anycast?

[@ankuragarwal9712]

What does advertising actually mean? Can you please provide specific term so that I can search about it and read?

[@PrernaJain-d4y]

When to use the Load balancer and when API gateway?

[@reena2485]

When LB stops advertising IP then who updates the routing table? That path from router to LB need to be removed. When failed site is up then LB advertise the IP, path need to be added back in routing table, how does that happen and who does it ?

[@AsliEngineering]

LDirectorD

[@rahulsangvikar7973]

@@AsliEngineering Since anycast doesn't perform healthchecks, how does it know that the LB has stopped advertising the ip so that it can update its routing table?

[@guytonedhai]

So even if 1 service under the load balancer goes down, we make the load balancer undiscoverable? Is my understanding correct?

[@AsliEngineering]

No. All the services. Google made the change to LDirectorD and added fallback command which does this. When none of the services are working it stops advertising itself as anycast peer.

Hi, before going through a paper, can you post in advance, so that we would also skim it through in advance . If you are already doing this, I am not aware of it. Please let me know where I can find the posts in ?

[@AsliEngineering]

I do it on all my social handles.
