Designing Workflows in Microservices - Orchestration vs Choreography

[@suriliagarwal676]

Make more such videos. The content and your delivery is amazing. Crisp and clear.

[@aishwaryasingh2021]

Thank You for presenting in such a simple and concise manner

Whenever I watch your videos, I am amazed by how easily you explain complex topics and the depth of knowledge you share about them. Thank you for providing such valuable content.

[@harshpatel105]

Great videos Arpit, loving the depth of the knowledge which is very hard to find at one place on the internet.

[@cksmcaitm]

Fantastic concept Arpit kahan se itni less age me itna good thought process generate kar elte ho bhai... outstanding... keep posting such a nice knowledgeble videos.

[@prabaharanmoorthy6865]

Very practical knowledge for day to day design tasks. Thanks for posting this.

Hey friend I have a question maybe you can help me? in this saga pattern with orchestrator approach, the orchestrator should have its own database also?

[@vikaspal8785]

Great content keep sharing it .. lot to learn . Currently we are using async comm. for sending otp notification to user. And sometimes consumers lags and there is a delay in otp received when a large no of request hit on user services.

[@AsliEngineering]

You might want to consider sync communication to send OTP for a great UX.

[@NBJavaDev]

Do these both patterns fall under SAGA?

Choreography looks fancy on its face and easy to implement but the edge cases can be tricky to solve. It would be great if you could cover the failure scenarios like what if an event isn't picked by any of the services; how do we track that or replay it, etc?

[@waleedahmad2012]

It seems to me that choreography has loosely coupled services that are easily extensible. On the other hand, Would you agree that orchestration has highly coupled services? If so, can we assume that orchestration systems are hard to test and change since they are highly coupled? and can we have loosely coupled orchestration systems ? any cons a system like this?

[@Satenc0]

Orchestrator can be used asyncrhonous too? Because then if we had a constraint of cant take more than 500ms to answer, then I would go with choreography so that when the order is placed we answer "OK we got the order", but with orchestrator we cant answer if it syncrhonous until all the cycle is completed which could take more than 500ms

[@rajnishmishra001]

In single application I NEED to apply both asyn and syn communication because the feature requires them . How do I proceed with this?? Should I tweak the behaviour a bit or go as I have planned already.

[@mdnayab5839]

That was very insightful. Please share your thoughts which one ( Orchestration or Choreography) would you use for fraud detection in a Payment

[@adilsheikh9916]

I think, Event Driven cant be mixed with Choreography, as in Event Driven, one service may not be concerned about who is consuming the events but in Choreography, service may be concerned about who is consuming its message. In Orchestration, I think, there will be a separate service which will be orchestrating all these services like Order, Notification, Seller & Logistics

[@adilsheikh9916]

If I send OTP in Async & move to OTP entry page...there provide 'Resend OTP' button which user can use if OTP not received. I also think, Orchestration is not about Sync, one can have Async communication there also. And I think, if hardware infrastructure & network infrastructure is not solid, then no software design can work properly, Sync or Async, Choreography or Orchestration.

Hello Arpit, I'm building loan application for my college project; I want to build form builder and workflow for that. I have orchestrator who manages current stage, next stage and so on. I want to understand what orchestrator can do and when workflow should be initiated? I have created multiple forms using form builder and those forms are assigned to different stages in workflow. according to me orchestrator is just responsible for marking current stage status and next stage status. Doest orchestrator will responsible for calling forms, and will it also responsible for hiding/showing form fields based on permissions?

[@rahul111191roy]

This was awesome..! Found my coach

[@R1996s]

The example that you gave for the recommendation service, say I send a request to recommendation engine to generate ids of videos to be recommended, couldn't I use choreography at the inventory to fetch details of videos like thumbnail, description and all by sending in event as video id in the queue, would such implementation be bad?

[@AsliEngineering]

You can. There is nothing wrong so long as it meets your user experience.

[@sohanlalgupta8996]

We are using combination of both(hybrid model)

[@jhonsen9842]

Why could you please elaborate the use case. Thanks

[@theerans723]

Great explanation !!

[@yogendragadilkar8898]

Very nice explanation... Thank you Sir 👍

[@YOGESHKUMAR-hd6hc]

Hi arpit, loved your video content. I have tiny request. can we have notes for this videos ?

[@AsliEngineering]

You can find them on my website arpitbhayani.me

[@ravindrakushwahakrishna]

Thanks sir for it

[@shishirchaurasiya7374]

I am into the process for upgradation to Software Architect 😎😎

[@ayushkapri9082]

I've a team mate who is obsessed with orchestration, I don't know why, every 10 words he places an orchestration word in between. I should send this video to him and get him to know that this term "orchestration" is obsolete. 😂😂

[@MarathiNationOne]

impressed

[@malikjon7619]

Would you build a micro services project?

[@RekhaS-t9p]

This is good

[@kalawatinarottam]

1 How the order service will get response 2 If any of the underlying service fail then how to handle

[@AsliEngineering]

message passing, webhooks, etc. handling errors depends on the usecase.
