Hi,
This is the PART-1 video of Microservices Architecture and its Design patterns.
Its a very important Hight level design topic
#microservicestutorial
#systemdesign
In this video we have discussed :
- Monolithic architecture
- Microservice architecture
- Microservice phases
- Decomposition Pattern in detailed
- Advantage and Disadvantage of Monolithic and Microservices

### Introduction - Part 1
- This is part 3 of the video series on high-level design
- Previous 2 videos already covered
- This part covers:
- Monolithic vs microservices
- Covering important microservices patterns
- Says this topic can lead to around 15 questions in interviews
### Disadvantages of Monolithic Architecture
- Tight Coupling
- Changing one line can impact other components
- Need to test/deploy entire application for one change
- Difficult to scale
- If one component needs scaling, entire application needs to be scaled
- Expensive deployments and rollbacks
- Entire application needs redeployment for a small change
- Large codebase
- Everything in a single application
- Codebase grows large over time
- Difficult to make changes, understand impact
### Why Microservices?
- To overcome monolithic disadvantages
- Split large application into small services
### Advantages of Microservices
- Better separation of concerns
- Loose coupling between services
- Independent deployment of services
- Easy to scale out specific services
- Faster release cycles
### Disadvantages of Microservices
- Proper service boundaries/decomposition is challenging
- Inter-service communication is complex
- Monitoring calls across services
- Handling failures
- Distributed transaction management is difficult
- Across multiple databases
### Microservices Design Phases
- Decomposition patterns
- Database patterns
- Communication patterns
- Integration patterns
- Deployment patterns
- Cross-cutting concerns like monitoring, logging
### Decomposition Patterns
- By business capability
- Split based on business functions like order mgmt, inventory, etc
- By subdomain - Domain Driven Design (DDD)
- Split large domains into multiple services
- E.g. splitting payment domain
Very well explained...awsome!!!
Great content as ever. Thankyou for such videos
thanks a lot
Got to know about this playlist from Linkedin, awesome explanation. Thank you!
Thanks
Love the way you explained this. Thank you 😊
Glad it was helpful!
t
Decomposition into microservices->database integration per micro service ->communication among micro services->integration to one gateway
Please do in English. Thanks for these.
In simple word "perfect"❤
Thank you
I have one question like sometimes we create jar of different projects/batch and when we run services and run any batch it picks up that jar and runs the code in it. is that following microservice architecture too?
Content and explaination is admirable.
Just one suggestion can you please use Dark Mode. It quite straining for the eyes. You can understand as a programmer 😃
Got it . Yes we are night owl, so i can understand
Very Nice Explained !! Keep it up
Thanks for the video.
Thank you
Very well explained 🎉
Thank you
Great explanation
Thanks
when we say loosely coupled, is it related to impact of system failure too? if order service is down, will the whole application still work properly? if yes how?
never mind, you have already explained my question in video. Thanks.
At 19min in video you have mentioned about having common database in micro services, it will make it tightly coupled again, I hope there will always be a solution to not to have shared database in micro services.
Even in DDD, aren't micro services ultimately still based on independent functionality??
Best
Thanks
Feedback -
1. Write clearly, very confusing writing, not able to understand properly
2. Need to be structured with explaining.
3. More details are required in explaining.
Great video got high level understanding.
I have few questions regarding decomposition pattern:-
1. These decomposition pattern must be used interchangeably like when business capability becomes big we need to divide microservices using ddd but my question is if we are creating multiple small microservices than we should not divide dB for subdomain as it will make break the principal of loose coupling and increase complexity.
2. More small microservices create difficulty in transaction management so how to handle that?
I am asking these questions by understanding things on high level only .
Hi Naman, pls check its Part2 video, i have clarified both in that video. Pls check once, if you still have doubts after that, we can discuss
@@ConceptandCoding Where is the link to Part 2. Nice work by the way !
@@mukulmangla632 ruclips.net/video/qGlUKtjqaEQ/видео.html
pls check the playlist
@@ConceptandCoding Hi, regarding the first question, will we ensure that microservices are not further divided according to subdomain using strangler pattern? Watched the second part but the first question asked by naman is not very clear, thanks.
22-5-2023 Thanks
There is a cut at 16:43 in which you were telling about, what is the rule for deciding how small our microservices should be, is it missed?
It's defined in the decomposition phase.
Hi sir do we have handwritten notes for this or any PDF so that we can revisit concepts
Hi Sahil, sorry i haven't saved it
10 min mein 4 ad aa gaye scalar academy k
any chance for English please ?
I would truly appreciate it if you could provide the content in English. While I was considering buying your Udemy course, I faced a dilemma because it’s also offered in Hindi. Consequently, I opted not to proceed with the purchase.
sorry for that.
@@ConceptandCoding I would greatly value it if you consider converting the Hindi video content to English at Udemy in the future
Thanks a lot for such a wonderful lesson. Sir I could not find this playlist. Could you please update the link.

I have made it private as DSA question already there at so many other channels
How to get these awesome notes?
Will share buddy
@@ConceptandCoding Thanks. One more suggestion. Why don't you come up with paid courses like others do. There you can put this in a more structured way and we'll get a chance to interact with you in live doubt sessions . That will help us as well as you get benefitted for all your hard work. Do you have any plans as such?
@@ConceptandCoding Hi sir can you please share notes
Sir first video aapka nhi mil rha h
Check the HLD playlist buddy
once monolithic is also known as microservice😂
Seems like just a way of making extra money apart from Paypal, so explained videos so hurriedly, even not shown running example of each pattern on IDE
He videos are the best. No question about that.
@@mayankb9 everyone has their own views, so no need to unnecessarily tell your point of view
