Hello again, I really understand now, also i read this doc from microsoft, which is not a good practice to do synced communications between microservices as they say https://docs.microsoft.com/en-us/dotnet/architecture/microservices/architect-microservice-container-applications/communication-in-microservice-architecture

https://docs.microsoft.com/en-us/dotnet/architecture/microservices/architect-microservice-container-applications/media/communication-in-microservice-architecture/sync-vs-async-patterns-across-microservices.png

So this brings me another question Isn't there anyway to get users without being coupled to identity service. For ex first thing that comes to my mind is to make identityservice not being a seperate microservice and include it in administration service? But probably it is the most used service? Why did you choose to make it a seperate service if it is gonna be coupled to administration service? or how do i need to do decisions when i am seperating monolith project to microservices? Is there any guide or docs or any book to read to learn more about it?

I really appreciate your help, and thank you for answering my questions.

Allright i think it is more clear in my mind now, thank you for the answer.

So to summarize, you removed internal gateway because there was only one synched (http) communication which is between administration service and identity service.

All the permissions are defined in application contracts, so this brings us to the conclusion, whatever microservice that implements permission manager module needs to define every microservice application contracts module, so permission manager can do crud operations on the permissions?

And as the last thing if i want to create a communication for ex between productservice and saas service

• I need to create productservice as a client in identity server give the scope as "saasservice"
• configure productservice by changing appsettings.json in the project like sth similar that has been made in administration service config.

"AuthServer": { "Authority": "https://localhost:44322", "RequireHttpsMetadata": "true" }, "RemoteServices": { "AbpIdentity": { "BaseUrl": "https://localhost:44388/", "UseCurrentAccessToken": "false" } }, "IdentityClients": { "Default": { "GrantType": "client_credentials", "ClientId": "Adzup_AdministrationService", "ClientSecret": "1q2w3e*", "Authority": "https://localhost:44322", "Scope": "IdentityService" } },

• And as the last step i need to have the "HttpApiClientModule" of the "saas microservice" in the "productservice module" and i don't need any contracts module since "HttpApiClientModule" also have a reference to the "Saas Contract Module" and this microservice doesn't manage permissions.

Further Questions:

• So as i understand identityclients options are configured in AbpHttpClientIdentityModelWebModule but in the docs it has been used AbpHttpClientIdentityModelModule can you clarify the difference between 2?

• Also if i am planning lots of communications between different microservices internally isn't the internal gateway with ocelot is better approach maybe it is not very efficient if one microservice needs to call another but overall can we say that if we have many communcations between our microservices isn't it better to configure an internal gateway instead of configuring all the microservices one by one? What i am asking is are you planning to replace back internal gateway with another solution than ocelot or is it gonna be gone for good?

Thank you so much for the help and assistance

Hello, I am new to Abp structure and i was checking out the docs for microservice structure, i have created a sample solution from abp suite. And i was going through the docs and trying to understand how the system works. I believe on the previous version, solution was using internal gateway to do the communication between services. Why was it removed in this version? Actually i am not sure what was the internal gateway was doing on the previous version. was it only a gateway that is publishing the events from rabbitmq and do the communication between all micro-services? And if it was doing all the communication between all microservices before right now how it has been solved? And i believe only "administration service" needs to make a call to "identity service", is there any other microservice making a call to other microservices?

I think all the built-in modules coming from Abp are now using static http client generation explained here: https://github.com/abpframework/abp/blob/dev/docs/en/Blog-Posts/2021-11-18%20v5_0_Preview/POST.md#static-generated-client-proxies-for-c-and-javascript I understand that administration service need to talk to identityservice and this is done with static http client proxies now. But what i don't understand is why administrationservice needs to depend on 5 contractsmodule which are

AbpAccountAdminApplicationContractsModule AbpAccountPublicApplicationContractsModule ProductServiceApplicationContractsModule SaasServiceApplicationContractsModule IdentityServiceApplicationContractsModule

i couldn't see anything on the documentation why these are needed maybe i am missing sth over here maybe it is related with static http client proxies. Maybe these are kind of basic questions but i am new to microservice concept and new abp structure. I would be glad if you could clarify those points for me.

ps: still on the doc it mentions about internal gateway which is not present probably it would be modified when the v5 is released. https://docs.abp.io/en/commercial/5.0/startup-templates/microservice/microservices#administrationservice
