Quiz for this video.
List down the real world use cases when you would choose a thick client architecture over thin client architecture and vice versa. List pros and cons in all scenarios. Can you think of a system which has thick client and thin client and multiple tiers? Also, can servers behave as clients?
Ma'am I can't stop my tears! Prof discussed but don't know what he discussed but your lecture gave me a better insight of topics. Thank you
My Answer to the quiz question
Q1 - Thin client chosen than thick client
The heavy computation required: The use cases where heavy computation is required, in those cases, we should do processing at the server only and not at the client.
Q2 - Thick client chosen than thin client
Light computation and less network access preferred: In certain applications where we have light computations possible on the device and the resource is heavy to be transferred on the network, in those cases, Thick clients must be chosen.
Q3 - A system with thick client Thin client and n tier architecture.
A good example of a system with all a thick client, thin client, and an n tier architecture is Zoom (I am not sure), because in case of zoom, streaming is done from the server, if I wanna change the background (Done at the client) and obviously they will have an n tier architecture to make a scalable system.
Q4 - Can servers behave as clients?
Yes, A client can act as a server. In cases where my server is making an API call to some other service (for example - Twitter API), the server is acting as a client.
I am a beginner, please correct wherever I am wrong.
Quiz answers:
1) When I choose thick client over thin client architecture : When a system want to takes care of more computation in the client side and want to relay less on the server side in this scenario we can go for thick client. Example: Ms-Excel, Ms-Paint.
2) When I choose thin client over think client architecture: When a system want to takes care of more computation in the server side and making client lite weight in this scenario we can go for thin client. Example : Web-browser.
3) Pros and Cons of thick and thin client:
Thick client:
Pros :
1) System can perform seamlessly without considering network latency.
2) More cost to maintain.
3) High responsive to the user
Cons:
1) No assurance of data availability as it has possibility of system crash and other difficulties.
2) High cost to maintain the app.
3) Effective usage of system resource is less.
Thin client:
Pros:
1) Easy to manage/maintain system infrastructure.
2) Highly scalable and easy maintainable app
3) Cost effective
Cons:
1) Highly dependent on network connectivity/availability.
2) Each components are managed by component professionals.
4) Thick client example : Ms-Excel
Thin client example : webserver
Multi tier example : youtube
5) Yes, Server can be a client also, because in large enterprise applications not all the apps takes care of computations some may get the other processed/computation result and take care of responsibility to get back to presentation layer.
where do you find the quiz?
how is this a pro?
3) Pros and Cons of thick and thin client:
Thick client:
Pros :
2) More cost to maintain.

Just letting you know - this course is awesome! Discovered you through the system design video with Gaurav Sen; and your content is gold. Thanks for taking the time to put together these videos!
In 6 mins you have explained it so much better than hours of lecture. Thank you.
I'm honestly happy with the 3 videos released so far. The content is well explained. Keep going
Thank you Sachin. :)
Thanks for the great explanation!
My answer to the quiz:
1. Cases to choose thick client architecture over thin client architecture:
a. Fitness App: As the data in a fitness app is user-specific, it would be costly and unnecessary to call the server for tracking progress.
b. Grammarly: Rules can be stored at the client end to make suggestions. 3 tier architecture can also be a valid option for this if the logic is too complicated.
2. Cases to choose thin client architecture over thick client architecture:
a. Stock Broker App: The client is just an interface that should be updated regularly from the server. All the processing logic also resides with the server.
b. Random key generation service: The logic for the generation and mapping of keys must reside with the server.
I am really spellbound the clarity of explanation. Really helped in my interview.
This series helps in bringing together loose ends and tries to give complete picture of overall System designing.
Thanks Apply
Great video
I still don't understand why some youtubers who just provide unnecessary roadmaps and give gyaan on how to crack FAANG interviews gets lakhs of views while someone like you who is actually providing quality content for clearing those interviews is getting so less views
Thanks a lot. We will get lakh views too. Things take time :) Keep supporting and sharing.
Hope so 👍
thats may be because people like to plan rather than following the plan
You're doing really good. :) Explanation was nice and crystal clear
The way you explain all the stuff is amazing. more power to you.✌✌✌
Good series on system design and explained in very simple way so that everyone understands. Thanks Yogita.
Thank you for the making the clear conceptual video.
Great video that was simple but very detailed. I learned a lot in 6 minutes, I am really enjoying this series. :)
Thanks Chuks. That's what we are intending bro so with to course 😅
Great explanation, I just hope and pray ther series expands and huge shoutout and appreciation to the creator and thier team. May God bless you all with health and wealth.
Thanks a lot for such wonderful wishes Raihan. God bless you and you family too 🙂
Thanks for being so concise.
A thick client can be chosen when more amount of processing work is to be done in the client side like gaming purpose, editing applications, etc.
A thin client can be chosen when computational processing is to be done on the server side of the system
An n-tier architecture can be chosen when the data stored in the database or the system is huge enough to be processed on the same computer or system and hence they are broken into parts , a very good example of n-tier system is social media apps like facebook and instagram which stores users data(number of users in billions ) and manipulate them according to the users requirement
On my 3rd video and I can experience the genuine effort you have put to publish the course and that too for free. Thanks a lot and wish you 100k subscribers soon. 🙂
Yogita, I must say.. You are too good 💯🇮🇳
Thanks for the course ❤
Great content with easy explanation to connect the dots
N tier architecture : heavy video games like valorant . They have load balancer. A lot of threads and entities to handle .
Thick client : Adobe photoshop . Mostly the client side has heavy load.
Standalone software like unity
One tier architecture: water reminder apps
Very crisp and clear, thank you for making these videos!!
Glad you like them!
Thick client applications normally require the installation of application on the client side (user application). They take up space and memory on users machine. Eg - Microsoft outlook
Thin client applications are typically the web applications which can simply be accessed by internet. Eg - google
Great explanation. Thank you so much
well explained on the situation we need different types of architecture with examples
Simple and elegant!
Best free tutorial on system design.. thanks a lot mam.. god bless 🙏🙏
Most welcome 😊
extremely good explanation
too good mam..... got my doubts cleared
Thank You ❤
it is really useful ..very good explanation keep going
One of the best series for Systems design beginners. Great job.
Examples
Thin client: Spotify
Thick client: Atlassian Jira, Wordpress
Two Tier: Simple full stack application
Three Tier: RUclips
Glad you like it Jafar!
You're a genius bruh
Thank you very much!!!
Ma'am very helpful in exam i catch my 10 marks in 6 minute thank you so much ❤️
Well Explanation ma'am!❤
Look forward to your videos on weekends..keep going.
Thanks Aakash. New video on Data and Data Flow releases Monday 10:00 AM(IST). Happy Learning
This is awsome explanation 🎉
thanks for your time
Great series
Thankyou for this series. Its a perfect place to start
Glad that you liked it :)
Thank you so much
i will be following this tutorial completly
Sure Shivam. Do join our slack group for collaborating with other engineers 👍. Link in description
Thanks alot
we choose a thick client architecture over thin client when most of the processing has to be done on the client side and when we don't want to have network blockage or highly depend on the networks.
where as we use thin client architecture over thick client when most of the part has to be processed on the servers i.e where the client has to relay more on the server side and there's less load on the client side.
As per your def, if data and logic resides on client, then it's thick client. If that's the case, what's the need for the server? Can you explain with real world example?
Great going. Keep doing such great work
Thank you, I will
Simple and to the point. 👍
Thanks Jinalkumar
Nice explained.
Thanks !
Facebook,Amazon- n tier architecture, since it has to serve market place, groups,etc differently for a wide user base. Apps like smallpdf , pdf resizer usually dont use a server to send data and apply the algorithms to resize or compress. So I think they are thick client ones since client does all that. Github-thin client since all the computation takes place in server I guess.
How does the transmission occur between 2 and 3 tier architecture?
Thanks
Ma'am, you gave the example of desktop video games, in that case who is representing the server side? Hard disk memory? Might be a dumb question :|
Wow !!!
Clear and nice presentation 😍
Thanks Athira
great content
There is a difference between layering and tiering, here you mixed both concepts
premium content for free. hard to believe
You're doing really well Sister. Keep ahead.
Thanks brother :)
Thankyou
really Great Explanation 👌👌
Thanks a lot 😊
Thin client: RUclips, Shopping apps, grocery apps, weather forecast app etc
Thick client: Ms Excel, paint app, recording app, etc
Is this series complete
#50k soon ❤️ thanks sudocode
SudoCudo can you make a video on WebSocket please?
Wow simple, short & amazing!!!
Thank you! 🙂
There’s one more architecture (single tier architecture), example is standalone games, ie everything resides and processing is done on the client machine itself. Also Multiplayer games can be better categorised as Thick client and thin Server architecture, ie game runs on the client machine which can take a lot of processing power and server acts as a data store to register all the data to keep the experience in sync for all the clients connected to the game server.
Absolutely Nishant.
1. List down the real world use cases when you would choose a thick client architecture over thin client architecture and vice versa. List pros and cons in all scenarios.
- Thick over thin
=> a heavy note-taking app like OneNote or Notion
Pros: More cost efficient as less resources will be required on the server-side
Cons: User experience can deteriorate if on slower machines
- Thin over thick => a portfolio website
Pros: Quick user experience
Cons: Less interactive content
2. Can you think of a system which has thick client and thin client and multiple tiers?
Instagram
3. Also, can servers behave as clients?
Yes. A server performing logical manipulations can behave as a client for a server that only serves data.
I'm a total newbie to System Design. So, my answers could be way off. Any corrections are welcome. Thanks!
Right on!
Example of thick client :Quicken. Example of thin client: MyChart (EMR). Correct?
Medam object oriented analysis & design .. uml diagrams , use case etc yeh sab kya system analysis phase me hota hai .. kya system alalyst yeh sab kam karta .. hai .
Thick client architecture is chosen over thin client in real cases-> simple link generator websites like tiny url as user dosen't do any computation
Pros are that user don't have to do much and cons are that delivery time can be more due to high computations
2nd scenario: in games thin client architecture is chosen as user has to constantly think and give inputs
Pros are that less memory required at server side and cons are that waiting time depends on user bandwidth
Yes server can behave as clients when they fetch for some data from another machine/server
Maja aa gaya
E commerce site is thin Client. Why so? I think Amazon is an N-tier right?
please enable captions for better idea for student thank you.
Is anyone making notes of these lectures, if yes, please do share? I am looking for notes.
Hi mam. In case of thick clients, the video editing software is a desktop application installed on my machine.
I dont need internet to do the editing. In this case there is no server as such. All the software is in client side only
Hey Ayush, that is true but video editing is provided in some cases online as well, for eg: RUclips's video editor or more example of thick client could be an online game.
@@sudocode when you say online game or editor, do you mean the ones accessed through web browser. If that is so, the heavy client side processing that you are referring to is the javascript execution in browser?
@@ayushbajaj1965 Why don't you join sudocode slack channel here - ruclips.net/user/redirect?q=https%3A%2F%2Fjoin.slack.com%2Ft%2Fsudocode-workspace%2Fshared_invite%2Fzt-h5bl54cx-TySBKH7faKBJ0MuCZk5Cow&redir_token=QUFFLUhqbHpEcDFWeW1mWTNrWEV4S1FVTldIbmUzNS1pQXxBQ3Jtc0ttNTAweXR1ZXl5VjBIQVNoT0NCYmFwQmZBU2xPVVBwNklGcUVUREZIRktreFBna3dvN1ZBbENBTW1hcXZlN2JwV3FBZHNjXzZfbWpSVXN4SHJYRGRDNGJtWElYNVZtdERDLVgzSU1HeXpDSDBlLWtZVQ%3D%3D&v=Dg1U-jwVUrg&event=video_description
You can get answers and also others can benefit too from discussion. But, short answer to your questions is YES.
@@sudocode I am a bit confused when you say online games are an example of thick client? It seems as if in online games the processing happens to be on server side and hence it comes out to be thin client, how can we say online games are an example of thick client? Also the link to join slack is not working would be great if you can share the resolution for this
Possible example of 2 Tier: A simple static website, for example I had a school project in which I built a website that listed my favorite recipes along with pictures. It was very lightweight and the data was not heavy.
Possible example of 3 Tier: An application like Redfin/Zillow, on which we request listings for homes in a certain area based on certain requirements.
Thin client: Instagram perhaps, all the processing is on the server side and I am mostly browsing/ uploading/commenting via the presentation layer
Thick client: Desktop application for Slack perhaps?
Good examples but think again for example of tier 2 and think if tier 1 is possible?
@@sudocode Interesting, Tier 1 seems to be a situation where the server is acting as the client?
when you have a lot of logic going on you better do it on server theb you should go with the thin client otherwise you should stick to the thick client.
when you have a lot requests and traffic going on your system then you would go with
client loadbalancer logicserver cache databse
other with stick to the client logicserver aproach is good
Thanks for providing such a great content.
Please correct me if I wrong anywhere
Yes client itself can act as server Example is calculator app and alarm clock app. Which is itself is tier1 and thick.
Can client be thick and thin both at the same time (hybrid)
What about the calendar app which has static and dynamic information both.. can we say it is hybrid ?
Please explain with diagrams
And make more videos
Slack link is no longer active. Please update the new link :)
Hi ,
I wanted to know if system design questions are asked for freshers??
It depends on company. Mostly not, for freshers DSA is focus.
1) List down the real world use cases when you would choose a thick client architecture over thin client architecture and vice versa.
Thick > thin: a drawing software (not online, because if it were online, it would be thin-client?), a video editing app, garage band
Thin > thick: simple website for querying train schedules, calculating tax payments
2) List pros and cons in all scenarios.
Drawing software
pros of using thick:
- has to handle a lot of user data (as strokes) and processing would be much faster if the logic was done on the client side
cons of using thick:
- processing will be limited by the compute of the client server; improvements to compute in the backend server wouldn't impact performance that much
Simple website querying train schedule
pros of thin:
- light-weight and cheaper
- does not need much data from client
- can improve performance on the backend
cons of thin:
- limited by network/communication
3) Can you think of a system which has thick client and thin client and multiple tiers?
Multi-layer: Netflix, RUclips
4) Also, can servers behave as clients?
Yes, when you start working with third-party APIs
Nice Content sister
Thank you 🙂
After watching these videos, I am going back to my college and demand a refund for the fee I deposited during 4 years of my B.Tech. Stupid faculty didn't know shit!
How to server work
🎉
Hmm
Also where are the quiz questions?
Did you find them?
Examples:
- Thick Client: Counter-strike.
- - Pros: Lower visual input lag.
- - Cons: Client requires good hardware - and not all do.
- Thin Client: Twitch.
- - Pros: Accessible to more users.
- - Cons: Processing costs incurred by company.
Thin:
Train Schedules
List of landmarks
Movie theater features
Thick:
On-Demand Taxi - Uber
Airline ticket sales
Yes, thin and thick clients can be found in the same system such as an on-demand app like Uber, where a robust logic engine is needed to connect riders with drivers, but thin clients regarding the name, plate, details of drivers which require no processing.
What architecture should I use for an e-commerce website inspired by amazon? three-tier?
Keywords:
Thin client
Thick client
N tier architecture
