The diagram used to explain the difference b/w monolithic and microservice is amazing, a clear cut explanation with advantages and dis-advantages. Thank you for this.
Your presentation is phenomenal! I learned more in one secession than I’ve learned in the IT field working for the past 5 years. Keep up the super awesome work! 🎉
Easily the simplest explanation among the videos i have checked in youtube. I am thankful for the time you have spennt on this. Please do continue to decipher the technology in easy to understand manner.
An explaination that would live by for a very long period of time. The diagram and the way you associated everything with it really made it very clear. Thankyou so much!
Ability to articulate, explain succinctly is an 'art', which you have mastered (been watching your videos). Given that i come from a risk/security background will help what security aspects should one consider in the 3 environments..Virtual, Containers, Kubernetes, dockers etc.
The differences were nicely explained. Especially I liked the fact, that you took an practical example and did an apple to apple comparison ! Just 1 change wrt microservices using database. It is possible that multiple microservices connect to same database and need not necessarily connect to a separate DB.
Thanks for your kind words. Its only supporters like you who could help me spread this knowledge. I am doing only out of passion and need to reach as many possible. Request you to share this with your friends, family colleagues. thanks again
Bro i have watched seriously every video that is uploaded on youtube and couldnot get a single clue what the hell is a microservice. But when i saw u uploaded a video on this topic. U literally came as a guardian angel from the first 3 seconds i knew u will not let me down. U r literally godgifted brother. May u and ur parents live 3000 🎉❤
This is very explain different the Monolithic & microservices with an example. so easily understand between this example given by this video. Thanks lots
Thanks Adi every business function could have a dedicated microservice and based on requirement could have common or dedicated database when interacting with other microaervices. But its not a Rule its a deaign choice you make while designing your application. Ex - An online movie streaming app could have a microservice to manage user login where they only user name and password so for such requirement they could go for a NoSql key-value database however once user logs in the other microservice handles movie browsing which needs other kind of storage so in this case you can have seperate databases.
It's a good idea to have separate teams of developers each working on separate business domains. This reduces the need for coordination between people since it's rarer to have changes across more than one business domains. it's also a good idea that each team owns its database and only allows access to it through it's API. That way each team can modify their database without worrying about braking other teams' code since they are not allowed to depend on a particular schema. So i think it's easier to manage changes if each business domain has its own db
I'm si grateful by your video AND your channel, It help allá the IT community, pls make More videos as this. Congratulations by your channel I've subscribed aleeady.
Yes definitely Kishore I am also old school in terms of scaling and have done several monolith expansions it's more intuitive for us but the kind of data growth we are seeing, microservices are now industry-standard for big data use cases.
Thank you very much for your videos 👍 you always have the best video to explain concepts in a simple means with examples. I really appreciate your work 🌟 keep moving forward !
Very good and simple explanation. Thanks for creating this tutorial. I have one question - You mentioned monolith application to be slow on performance. But is it not the other way around? Microservices need to make remote API calls. Does it not make micro services slower on performance compared to monoliths where all transactions are internal?
Micro services can be scaled selectively to improve performance. Also mostly to do with the way the micro services are implemented. In strictest sense, the micro services should be self contained and not make the unwanted internal API calls.
Hello, I was wondering if an application be be half monolithic and half micro services. We are thinking of using microservices only where needed. Please advise. Thank you.
Hi Syed the whole objective of kubernetes revolves around managing containers and container based microservices so technically you may create a monolith but then there is no point of using kubernetes
You can actually make changes to the monolithic architecture in this case your hotel booking. You don't have to bring everything down, you'll just have to redeploy the whole application.
If there is a change in one of the business services let's say Hotel Booking, unnecessarily we have to deploy rest business services without any changes in them..That is one of the disadvantages.
@@sandeeppachkawade in todays modern application development and with the integration of CI/CD pipelines, you don't have to bring your whole systems down to make changes to a specific features as ex; (the Hotel Booking feature) when using Monolithic design. You can make as many changes to an application features and deployed those features in Realtime. But again, it's always good to follow conventions and what work best. If am building a side hustle project, I will go with a Monolithic approach and if am working with a team and building complex project then I will prefer Microservices.
Great video. The point where you say monolithic is not going anywhere is so true - The product that I work in, is so complex - contains both Monolithic + Microservices. Uses multiple tech stack PHP and java webservices. Web methods are internally calling each other. The product has Jersey, spring boot rest, soap and what not. Things are so complex. Tech companies although are so obsessed about micro services. As, pointed by Hiral, why are monolithic web services slower, when everything is inside one app server ? Microservices keep calling each other and multiple db's , shouldnt that overhead make them slower ? Btw I watched it at 1.5X speed - Wrapped up quickly. Thanks for awesome video !
Thanks for the video. Do you consider 3 tier application as monolithic ? if yes, the example you gave for hotel business expansion, if the project is written in 3 tier, for certain changes, we had a choice to deploy the business later or data layer or both. So in context of 3 tier, can you please clarify about "whole application go down and re deployment as one" ? Thanks
Good question Viraj, so yes a 3 tier application can separate your web, app and DB layer however its still be a monolith in a sense that a 3-tier architecture can only separate the environment based on technology not based on business function. So for ex even if you have DB and app servers on 2 diff nodes on cluster there is still potentially a single point of failure business wise unless. In monilith we somewhat help this situation by having a clustered environment but that still does not allow us to make changes based on a business function like a microservice can do. Even if you are somehow able to completely seggregate it ona monolith the cost, efforts, time and complexity would be massive compared to microservice. Hope I was able to answer your query let me know your thaugts and keepnsupporting thanks. Anshul
@@ITkFunde Thanks for the answer. I was more referring to a 3 tier architecture scenario in where the BL and the database SP contain the business logic. If i deploy an SP containing the business logic or a BL layer compiled dll to application server, can that still be considered an overall application outage for deployment ? I would think microservices would have an individual integrated BL pieces baked in togather, the business logic and the data in one single service. but what if multiple business services needs to open and close database connections ? in that scenario, is it advisable to create a separate service /api for db operations ? or "copy over" the same db operations across multiple services ? Thanks
Thanks Viraj, I know where you are coming from, and in a sense as I said you could make your monolith flexible, but what if your whole database server itself crashes or you app server is shut, also when you seprate business function underlying db layer should be seprate to make it complety fault tolerant. In Micorservices you can have your one module deployed completely independent in a container..also you can multiple DBs holding seprate functionality. Suppose netflix login page module can be on small relational database however its content page can be on a big data database. Both modules can expose its Apis and talk to eachother. So to summarize yes monolith can be made flexible but only to an extent. Thanks.
Will I be correct to say microservices are for apps with a huge base of users and monolith is for smaller or medium scale apps Z. Then is it possible to have a microservices architecture for a single language like rails or Django instead of multiple languages across the backend
Good sharing! If an application that all the business unit can be total isolated except share same user account. How do you think by using subdomain vs Microservice?
Very nice tutorial well explained. I have one question suppose microservices divided into separate unit then how for eg: travel bboking need to the payment then how the two database make relation?
The diagram used to explain the difference b/w monolithic and microservice is amazing, a clear cut explanation with advantages and dis-advantages.

Yes it is possible. but it name it as distributed system
Good explanation,this video should have got more views

simple and clean explanation for every one.
Thanks for good explanation.. Still you can scale monolith by adding more servers behind a load balancer with sticky sessions or session replication
Yes definitely Kishore I am also old school in terms of scaling and have done several monolith expansions it's more intuitive for us but the kind of data growth we are seeing, microservices are now industry-standard for big data use cases.

What shld be the architecture for core system in life insurance company
Does microservice architecture has separate front end for each service ?
Answer is it depends ! It depends on your system design. You can have one front end for multiple microservices
Thank you sir. I am starting to understand this concept.
This is realy good , I like your explanation .
Master indeed, sir do you have an full course on k8s please?
Brilliant.....well explained 😃👏
Thanks a lot sir... great explination
Great explanation! Thank you.
Thanks Mario for your kind feedback. Please share this initiative with others. Cheers Anshul
Wonder full
Thanks Nagendra
Very nicely explained
Superbely explained...👍👍👍
Thanks Rahul 🙏🙏
Great talk !! it would be great if you can explain what kind of testing varies between monolithic and microservices

Good example
Thanks
superb lecture thank you its very helpful for me .
Thanks for the informaiton. what does API gateway map to here interms of infra ?
Excellent sir
How can we relate foregin key relationships among these micro services
This is best..and provide more..
Awesome Explanation...
clear explanation.thanks
Nicely explained bro….!!
U r a an absolute legend
So can we tell which service is monolithic/ microservice in a real time senerio

Can u explain more on synchronization of diff services and db in continuation with the example in the video without using container or wrapper
thank you sir, grate video, you made it easy for me
Good explanation. Thank you

Very good !!
Thanks

Z. Then is it possible to have a microservices architecture for a single language like rails or Django instead of multiple languages across the backend
Hi ,
Could you kindly help me out with AWS , Kubernetes and testing cloud infrastructure
Good ! BTW which mic you usedfor this video
Hello sir ,I want to switch new technology so I choose informatica and micro services
Plz suggest which one is better have future
depends on your current skills
👌👌👌
How does databases of each service can interact with each other ?
Good sharing! If an application that all the business unit can be total isolated except share same user account. How do you think by using subdomain vs Microservice?
Really nice video, Thank you
Thanks Amarnath
thanku so much for uploading this video
Very nice tutorial well explained. I have one question suppose microservices divided into separate unit then how for eg: travel bboking need to the payment then how the two database make relation?
well explained. Thank you.
Thanks
Which technologies can be used to build microservice architecture for any software development?
