In the video, I discussed the revival and importance of Remote Procedure Calls (RPCs) in facilitating inter-service communication over networks. RPCs aim to make network calls resemble local function calls by abstracting complexities like serialization and transport. I highlighted the significance of standardizing communication between services, irrespective of languages used, through RPCs. The concept of stubs in RPCs was explained as the entities responsible for converting requests and responses between services. RPCs offer a seamless way to handle remote calls, improving code readability and efficiency.

Man, you are so good. This is the best video on RPC I have ever seen.

[@AsliEngineering]

Thanks Niraj :)

[@karthikeyanarla4163]

Bro, I am addicted to your videos. Another disease broke out......

[@hyrdeshgangwar]

Great explanation. I've worked on gRPC before but this video helps to understand the place of gRPC in the software ecosystem .

[@sarthaknarayan2159]

Love you explanations. Can you please create a demo on how to use RPC? Thanks

[@abhishekray4668]

I was just reading about protocol buffers and then you come up with RPC...i feel like the universe is trying to tell me something

[@AsliEngineering]

Go for it man 🤘

[@LogicArray]

Hello Abhishek Yes it is , Would you please let us know which article or a book you referring to it?

[@mohitkumartoshniwal]

Informative in-depth video as always.

[@RaviKiran_Me]

How did I not know about RPC till date? reason being no one explained it so well. Thanks Arpit. !

[@adianimesh]

Awesome ! I thought I knew RPC but then here I am after 32 minutes well spent.

[@sashibhushanarajput1194]

Thanks a lot Arpit for this video

[@underdog27money52]

Definitely worth watching 33 minutes well spent :)

[@akankshakumari213]

Can you also post a video on detailed demo of this? That would be helpful👍

[@sanjeevrajora7335]

really great and informative video, thanks Arpit

[@kushalkamra3803]

Thank you Arpit 🙏

[@nagesh007]

Awesome 😍

[@Aditya_Vyas]

It was a nice Video.

[@harshitagrawal1396]

Nice and informative video. However at 7:30, you mentioned that there is no standardization in Rest and you need to handle things in different way in different language. I am 100% clear because as per my exp, I have used REST in XML and JSON only and HTTP calls doesn't depends on any language. I have done some of my code in python, deployed it lambda and called it from .Net application. I have not faced any issue due to language.

[@ubaidmanzoorwani6254]

Your video are great, just one request please also make hands on video on these topic too.

[@shriramparamesh]

This is superb. How do you customize errors if rpc takes care of the errors and retries.

[@maniraja1089]

Hi Arpit, We can generate client/server stubs for rest(jax-rs) and they offer anstraction. So, what is the exact benift we get with rpc over rest.

[@bostonlights2749]

Nice video. Reminds me of AIDL in Android

[@rjarora8372]

Nice video Arpit, but this topic is definitely incomplete without a thorough demo. A thorough demo video would be really helpful

[@aatifnazar8203]

I have been using feign clients for inter service communications and they handle errors (backoff, etc) internally

[@vidyaarkeri7930]

I am having an issue with generating the pb.go file.. It is not cotaining registeradvcalcservice

[@arjunnayak9088]

Would be great to collaborate with you. We at mavonic build scalable systems too

[@Gagan21081]

I have one issue, after stopping the rpc service it's again listening to some port. How can we get to know why it is still listening

[@karthikiyer9834]

Hi Arpit Sir. A question. So for the client-server RPC communication, how will the client stub know what IP Address to communicate to?

[@AsliEngineering]

You create the connection and initialize your client with it.

[@karthikiyer9834]

[@ankiy]

Hey arpit i m new to system design can i purchase your course . My job is QA. But system design is something which also interests me. I have some knowledge about the architecture design the project i am working. Do recommend me ? Your course if not from where should i start with system design.

[@AsliEngineering]

There is a pre-requisite section on the course page; I would encourage you to check that out. There is also a YT playlist attached with the necessary topics.

[@rahulsarkar4206]

Possible to create a video on interservice communication describing HTTP, HTTP2, TCP, UDP, connection pooling, multiplexing terminologies in details? How a change of contract on a service is handled on which many other services are dependent?

[@AsliEngineering]

I cover it my cohort course and hence cannot put it out on KZbin. Apologies.

[@rahulsarkar4206]

[@ALOKSINGH-hs2uc]

Some code would be better to support your words and helps in understanding the flow.

[@jivanmainali1742]

Could not get why cant services written in two different language communicate ? Its quite possible with any client library if we have an endpoints.

[@AsliEngineering]

But how client libraries would talk? What protocol would endpoint be exposing? That is what determines the inter-service communication.

[@reallylordofnothing]

@@AsliEngineering If you expose a REST endpoint, it is assumed due to the verbs - GET, POST etc - that you are using HTTP protocol. What is that got to do with client libraries? Any client library - python, java, ruby - would be able to communicate with an REST HTTP endpoint and pull data in xml or json etc depending on how the REST server decides to publish its response.

[@codedusting]

How is it better than JSON? Didn't understand

[@AsliEngineering]

Protobuf packs data more efficiently than a JSON. So fewer bytes to send over the network.

[@codedusting]

@@AsliEngineering Understood

[@DeepakKumar-uz4xy]

rpc are used bedefault in ethereum blockchain. each node talk to each other using rpc.
