In my last video, I walked through what is my understanding of microservices. Based on my readings and practical implementations. What worked for me and the philosophy I follow when building microservices.
In this video, I will walk through breaking out a microservice from an existing monolithic demo application.
The goal of this video is to show the process I follow when breaking out microservices from an existing monolithic application.
In this video, I also talk about using Dapper, which I do not cover in this video. But here are the link of a couple of my videos on Dapper:
• ASP.Net Core with Dapp...
• ASP Net Core with Dapp...
I also talk about microservices resiliency and using Polly. Here are the links for a couple of my videos on Polly:
• Microservice resilienc...
• Microservice resilienc...
This video does not cover all aspects, but what is the general direction I usually take when building microservices. Please provide your thoughts and questions in the comment section below. And I will attempt to answer all of them to the best of my ability.

i write rarely comments on youtube, especially when it comes for coding, tehcnologies and etc. BUT your series about microservices... IS THE BEST ONE, could not skip to tell.

@Cullen Gunnar thanks so much for your reply. I found the site through google and I'm waiting for the hacking stuff atm. I see it takes a while so I will reply here later when my account password hopefully is recovered.

Hi Sir, This is a great tutorial! Very helpful! Can I request you kindly to upload both the solutions to GITHub? 🙏

Many thanks for your video Sir. Please are you able to share the code of the Ecomm application as a monolith and when you break it up into a service. many thanks for your kind consideration and look forward to hearing from you.

@DotNet Core Central Nice work you are doing here. Mine is not that of a big issue. I would just like to request for you to name/arrange your videos in order. It's a bit hard jumping from video to video seeing which one follows which. E.g 1) RabbitMQ .... Part 1 2) RabbitMQ ... Part 2 ... 6) Ocelot

@NIMROD MAINA, thanks for the suggestion, I will do that.

Hi Choudhury, Thank you for your nice tutorial. I wonder if you have the solutions of the Monolithic and Microservice Applications available for reference.

@akashthakral9181 Год назад

Great Videos. Appreciate the effort!! However I have one confusion. You have added User name and Product name in Order service DB itself but if for some reason, the product name/username changes, we would have to change it in both places and that violates the fundamental concept. Also if order detail service is dependent on user/product service for attributes, how should it actually get the data.There could be thousands of rows in order detail and if we fetch attributes from another service in iterative manner, it would be distareous. PLs suggest

@samayhaider 3 года назад

With this architecture, you would have to host two applications? One would be the wrapper that accepts the api calls and the other would be the actual api that is making the call to the database?

@DotNetCoreCentral 3 года назад

@Sam Haider, no, you will make multiple microservices, there is no need for any wrapper.

@manuelguerrero9917 3 года назад

The approach that you use here to merge/join data between Microservices is called Selective data replication, correct ?

@DotNetCoreCentral 3 года назад

@Manuel Guerrero, thanks for watching the video. This is kind of SDR but not exactly the same based on my understanding of SDR. SDR is a concept replicating selective data sets to a secondary database. Whereas here we have multiple domain-driven microservices, which are keeping data necessary to their own domain, which is of course sent from the primary data domain. But not for the purpose of the data replication, but more for supporting the other domain with its need for functionality. Please let me know if it makes sense. I am more than happy to hear your point of view. Thanks!

@manuelguerrero9917 3 года назад

@@DotNetCoreCentral Yeah make senses, I was just looking for information about Microservices and I found a couple of articles that said that we shouldn't make merge/join between tables in different Microservices, because how you have been saying, a mc should work on its own. So I would the same technique you used here, I am going to create table that has the necessary fields so it won't have to go to another service to get data or something like that. I don't know why I keep thinking that I may later go to look data to another Microservices and I would have to make a join which I think its wrong.

Hi @dotnet core central kindly arrange videos in order, you did a lot of work but i guess all are not reflected in your playlist or vedios section. just saw 4 more links in the description section :-)

@Zeeshan Asghar, thanks for the suggestion, I will do that.

@shreyasjejurkar1233 4 года назад

Practically order service should be transient, correct? Because we don't want to share the order with multiple users' requests!

@DotNetCoreCentral 4 года назад

@Shreyas Jejurkar, correct when configuring in Dependency Injection container. Thanks!

@shreyasjejurkar1233 4 года назад

@@DotNetCoreCentral yeah, you can also use HttpClientExtensions so that you can do client.GetFromJsonAsync() directly, rather than getting the response and then deserializing into objects. Just add System.Net.Http.Json to the project.

Can i get real world use of microservices according to me breaking entity doesn't makes sense

@DotNetCoreCentral 3 года назад

@Rushang Panchal, thanks for watching the video. In this example, I did not break out the entity but essentially broken out the domains. And that is what we usually do in real-life is breaking out the domains and create services based on domains or sub-domains. I hope this answers your question.

how to authenticate user in microservices

@DotNetCoreCentral Год назад

it depends on how microservices are implemented, if they are behind an API Gateway, in that case the authentication will be managed by the API Gateway.

It would be nice if somebody did a real world example with business logic instead of these simple data type microservices. These are simple that anyone can do, try something more substantial.
