I have been exploring Microservice Architecture, and even though the technologies I use are in Microsoft Domain, the question is generic.

I get the Idea of API Gateway esp for things like Authentication. The pattern I am roughly following is based on CQRS + Event Sourcing

Request-> Command ##CommandBus##->CommandHandler -> Change Aggregate State->Store Events-> PublishDomainEvents ->Publish Integration events ##Event Bus## -----> Update Read Models

Many times initial Command will be handled by ProcessManager (consumer) to Orchestrate workflow.

All Microservices Application Layer consume Command from Bus and work on changing Aggregate state. Once done, the Read model store is updated. Currently, there is only a single Read Database which is updated

When I started with Command Bus, The REST API per microservices were for mainly Get requests ( Read ), which would dip into the same Read Database as all other Services and rest for accepting Command from Gateway.

Based on my current Scenario, Is there a logic in having REST API's per Microservice? I know we can do Async with Rest API to push commands, but what is the point when I am already using a Bus.

But now I am thinking of not having API per Service but rather API's based on usage. It's then not limited to single Gateway but few Gateway API projects.

Are there any Cons/ pitfalls with this approach?

Edit 2-- **Trying to rephrase if it gives context ** My microservice structure is very similar (to what @mrdnk commented) . As you In I will introduce technology to make it more clear. I use Mass transit over RabbitMQ for inter service communication.

As of now I have API gateway used by client applications, which would then call appropriate microsservice API to push a command object. the API method itself acts as a Command Handler (acting as Application layer) calls Aggregate and make it undergo changes. Domain Events based on the change are published within the process with Mediatr. Any events that outside (microservice) world needs to know is published on the bus. I started to look at the communication and said to myself why not use the Bus also for commands (as command bus). That way I can have more reselient and async process.

Application layer will listen to command and handle appropriately. This way I feel the service is more encapsulated. On API side (individual microservce) I dont need to expose any rest api for use by gateway. API in Gateway wil listen to request and create command object. this will be queued to bus. Consumer (command handler) on Microservice will consume Command and so on.

Currently all Writes are eventsourced (mongodb). Reads go to SQL Server. I can create API just for Queries from Read side. No more need to have Http API from Microservice at all.

I know technically it would work but Dont know if there are any pitfalls.

I'm looking for advice on how to structure namespaces in a CQRS structured application.

Currently the command-side and the query-side are in the same namespace in each bounded context, but as complexity is growing, it is starting to create problems.

Currently the structure has the following folders which each contains the implementation:

Good afternoon,

I am following the tutorial on Windows 7 for an Ipad on IOS 9.3.5 :

https://medium.com/flutter-community/developing-and-debugging-flutter-apps-for-ios-without-a-mac-8d362a8ec667 and I'm stuck at rebuilding the Flutter Tool. (Last part of the tutorial)

I downloaded (from the link of the tutorial) and copied in C:\src\flutter\bin the libimobiledevice, ideviceinstaller and which binaries. Then I ran the git apply ios.diff which gives me multiple errors, sometimes it's just about mac.dart, and sometimes it's more like this :

I got this error:

(I can give more info from inspector)

System.ComponentModel.Win32Exception: 'access denied'

The exception was originally generated in this call stack:

System.Diagnostics.ProcessManager.OpenProcess(int, int, bool)

System.Diagnostics.Process.GetProcessHandle(int, bool)

System.Diagnostics.Process.GetProcessTimes()

System.Diagnostics.Process.StartTime.get()

ConsoleApp1.Program.Main(string[]) on Program.cs

There is the code:

(I was running this program as administrator since the beginning)

The correct answer is how to ignore exceptions, because the error occurs because certain processes cannot be read even if you have administrator privileges

Problem

When I instantiate an instance of the Service class - derived from the ServiceBase class - the constructor I create for the Service class is skipped during instantiation. Then when the line "private ServiceController controller..." is hit, it fails because the ConfigStream object is never passed to the Service class variable _configstream. I don't have issues with constructors being skipped elsewhere in my code. Is this related to the use of the base class ServiceBase?

I've tried including the base class constructor like:

I have this map map> processmapram where the key is an integer and the value is the class object. This is how values are inserted to it.

I am able to execute a command inside the server but I want to get that output in my local pc. I don't want want to use ssh keys. I want to use just the host's username and password as well as vm's(server's) username and password. I couldn't find a direct method to get the shell output of server in my pc, but this method seems half done like generate and save the output in server and then get the file from server. I am finding it difficult to get file(sample.txt) from server to local host(pc).

[EDIT: I am able to do this using via via method(Store the output to server and then get it back into local pc, is there a direct method ?) ]

Is there way to retrieve Azure function trigger info (like service bus topic name) from execution context? I was trying to create generic LogError function that can be used in different azure functions like in example below:
