Azure App Configuration for C++

[ahaeber]

Is your feature request related to a problem? Please describe.
Azure App Configuration works great in ASP.NET Core applications. It would be good if we could use it in C++ applications too.

Describe the solution you'd like
Add support for using Azure App Configuration to this SDK as a separate component.

• integration with Azure Key Vault would be great.
• support for primary and secondary App Configuration instance for high-availability.
• support for offline caching, i.e. it can store the "last known good" configuration encrypted on persistent storage.

Describe alternatives you've considered
Considering to use Boost Asio or Boost Beast to integrate with the Azure App Configuration REST API. Another alternative is to use cpprestsdk.

Additional context

• Azure App Configuration REST API: https://docs.microsoft.com/en-us/rest/api/appconfiguration/

Thanks @ahaeber for your interest in the C++ SDKs. We are currently focused on enabling Azure Storage scenarios for the first release, with KeyVault coming soon as well, and we will look at App Config as part of future planning.

I am curious to learn about your use case and scenario that is requiring C++ support for Azure App Config specifically. What type of application are you working on and how does that integrate with your ASP.NET usage, if at all?

Hi @ahsonkhan, thanks for the reply. It makes sense that you start with Azure Storage since that is an important enabler.

We have a system with two layers that work closely together. At the top we have a .NET Framework application that handles user requests including a scripting engine. On the bottom we have a C++ application that do the low-level processing and integrate with a separate "engine" provided by a third party. Various requirements, including real-time performance and integrating with that vendor, is why we choose C++ for the lower-layer.

The plan is to migrate the .NET Framework app to .NET 5 and use Azure App Configuration to configure it. Therefore it would be good if we could use the same config store for the C++ part as well.

Hi @ahsonkhan , any update on c++ api for Azure App Configuration?

[ahsonkhan]

Thanks for asking @sreenivasp, we have been looking for more customer requests, like yours, that would benefit from supporting this (or any other) Azure service in C++, to help motivate the effort.

Can you share a bit more about your need and what types of applications you are developing, specifically in C++, that would make supporting Azure App Config useful for your scenarios?

Hi Ashon, Thanks for getting back to me. its a client application doing Azure configuration api call. For now using simple REST call using libcurl to get authtoken and using this token to call configuration store access calls. Thanks.
