11:33 Yes, totally agree. Think first instead of moving into the new fashion tech stack.

Great summarization of the Prime Video Case Study!

[mefirst]

When I was in computer science school twenty years ago, we were taught that "silos are bad" which microservices are based upon silos. I think the pragmatic real world answer is "it depends" as Amazon is learning in this case study. Monolithic and microservices are both tools in our toolbox.

[mavurugangadhar]

One of the main advantages of microservices is that multiple teams can focus solely on their service, making the release/deployment cycle faster, along with benefits such as independent scalability. With a monolith, cross-team dependencies will increase, and the release/deployment cycle will slow down adding scalbiltiy challenges.

So, it seems like there is a trade-off between cost savings and quick deployment/maintenance.

Agreed I'm not sure this is monolithic in nature. Also microservices have to be evaluated to see if they are the best tool to use. There is a lot of variation in what comprises a microservices and often discussion of a nanoservice vs a microservices. Microservices are often broken by domain and hence can have more then one piece of functionality grouped in the service. When choosing architecture it always comes down to it depends and of the largest factors is cost.

Nicely explained. Important point is that people making a buzz that entire Amazon Prime is moving away from Micro-Service architecture is wrong, its just their monitoring system, the old architecture seems over engineered to use S3, Lambda, Step functions for such high volume real-time video stream analysis and defect detection system, with the new architecture they just doing in single process to reduce the data transfer and persistence cost with improved performance as data transfer and processing happens now in-memory.

[gautamsinha]

From the study it is clear that this has been implemented for one functionality of error detection and smoother rendering of videos, not the total application but a contained function. So the earlier decompetition was mainly over engineering... Is my summarised understanding correct?

[JaNaMSoNi]

Thank you for the detailed information 🙂

[Jokikiolu]

Thanks for this excellent explanation but is this really a monolith? This service has a very specific task and also stateless which would give a significant cost saving

LOL 😂 previously the craze was for Serverless now its going back again 😂

[itsnarahari]

Bro Monolithic it's like a rod currently I am working on the Monolithic project for small change we are doing re deployment and it will takes forever....8 hrs this bothers me with this issue we are thinking 10 times is this change is required or not...to fulfill that functionality in other ways but our hairs are falling down but no way we will found eventually or finally We need to change the code 😊

[crimsonx_]

too many microservices are really a mess.... 😭 sometimes i think to give up my software engg job.

[prvinsharma]

Is the final video which is uploaded to S3 saved permanently or is it recomputed for every client request for the same video? Or is it region-wise S3 videos are separated and reused?

[garavind]

Will Amazon prime cost reduce from this

[phyohtetpaing]

But I think they are still using replication for the s3 🪣. Each s3 prefix link only support 5k read head and 3k write head .The only outbound rule is from s3 to cdn .I think they did use S3 replication and reading the data to CDN and return to the users with closest Starbucks locations and it still need eventdriven microservices .Overall it didn’t fully migrate to the monolith way.
