Excellent explanation..! 👏 

But I have one query. @5:07 I am not able to understand why do we need the load balancer at all? If we configure our instances to scale automatically (GAE/ Cloud Run), won't the new requests will automatically be routed to the new instances?

Akka, Orleans and other Actor-model frameworks solve most of the covered problems related to statefull architectures. It is amazing to see how technologies evolve so fast

This is the best explanation I ever listened thank you for making this

[cristian-bull]

being new to this topic, I have a very basic question.
If I go for a stateful architecture, is there anything that needs to be done to guarantee that the requests from the same user always go to the same machine? is there any way to guarantee that? (at least as long as the instance is up)

[soumyadipchatterjee]

Excellent blog with clear and concise manner . It absolutely clear concepts about Stateless vs Stateful .

[r.simhadrisimhadri]

good Broo, need more concepts in System design

[sanjeeva_info]

Excellent content and explanation 👍👍👍❤❤❤

Thank you! this is very helpful to begin with stateful/stateless arch.

[anandakumarsanthinathan]

Very useful and informative video. With the advent of Containerization, apps being stateless became a necessity. Not only stateless, there are other requirements too such as not writing to the server's file system, etc.

It was very well explained even i am not a student of cloud computing but i have understand what he said..

[karunakarh]

Wonderful explanation! Keep up the good work.

[mentalisme]

The only thing you truly explained to someone who truly wanted to understand was what a stateful server is.

[majaysakthishankar]

Make more videos of this kind. Thankyou

[압둘하미드이드리스]

Is there a tradeoff in 'stateful' and 'stateless' architecture with respect to HTTP?

[sadathghouri]

Appreciate your effort in explaining flawlessly. 👍 for the crisp presentation slides.

[ThiruSings]

Thank you dear GK. It was an amazing yet simple explanation. You keep us connected to your channel. :)

[kavibarati]

This video is very useful for me 🙂 really thanks for making this kind of videos 🤟

[trafficface]

That made sense but stateless seems to still have state just kept out of the server, the server is readonly delivering state to the client, correct?

[raajvlogs]

I have some confusion.. how the files sync in each server.. ? ( Db question, do we need to replicate databases if load increase on database too)

[sudheerg]

I am learning AWS now and come across state full and state less in network topic ... but in that topic they said state full will remember and stateless will not remember anything . Is what you are discussing and what i am reading both the same i doubt .. if yes which is the correct one ?
