Scaling in a nutshell | Horizontal vs vertical scaling | System Design Tutorials | Lecture 17 | 2020

This is the seventeenth video in the series of System Design Primer Course. We talk about one more important component of System Design: Scaling.
We want software engineers and aspiring software engineers to develop basics and get ready for the world of interviews as well as excelling as a Software Engineer.

[EakanGopalakrishnan]

in case viewers are wondering, there are other names for this which is used in the industry:
scale out - horizontal scaling
scale up - vertical scaling

[musical_nights]

Thanks so much for explaining Scaling with a perfect example!

[ismile]

Thank you. I THOUGHT I know this topic but after seeing I got more insight of it.

[harishjoshi]

Very nicely explained with a real-world scenario. Thank you

[ChandraShekhar-bycd]

Happy New Year. Thanks a lot for staring the year with such an amazing video. Hope to have more videos in the coming days. :)

[simprodigy]

yogita you should add links in description that actually go in depth about scaling as you mentioned in the video all things distributed is a good start. i usually find it hard to find the links that you mention.

[anilkumar]

Can not we say, increasing the number of tables is vertical scaling, and opening similar new restaurants is horizontal scaling? Number of tables in a restaurant has a limit (say 8, 12, 16, ... tables), but after a limit you can not vertical scale.

[jaytube]

Thanks! Great explanation. Very relevant real world examples.

[rupeshjha]

Nice explanation!!
One thing I wanted to ask is why the Relational database is more Vertically scalable and no-SQL is Horizontally scalable??
Why we say Relational database is more vertically scalable why not horizontally?

Also, ma'am if possible please make a video on an event streaming system like Kafka..

[eddanapudir]

Very well Explained. Thank you very much.

[amantarar]

make a series on operating system also

[AkshayMukadam]

How do we decide, how many number of nodes needs to be added in horizontal scaling . Let say we have a service X, initially it was having 100k request with 2 nodes(Node number was taken at random), but after 2-3 months, the system is receiving 1000k request, how do we decide how many nodes needs to be added for horizontal scaling

[prateek.mundra]

Can you share all the resources link of entire playlist in a single post

[muskangupta]

Please attach the resources in the description

[harshitpandey]

Hey, can't find any resources in the description.

[govindkraditya]

Hey Yogita! Very well explained.. Keep up the good work. Just an approach as to how to decide the ram and cores of the machines for deploying the systems based on the number of concurrent requests per second as a part of vertical scaling approach, can you throw some light on it..

[manu-singh]

Hi Yogita, I wanted to ask if lecture 16 is missing or it's just a naming error in the Playlist

[Live-hhli]

I want to ask that
Will this playlist be enough for sde1 or sde2 interview?

[hi-kamalesh]

have anyone notice every video has a dislike (3) cosistency.
