Azure function architecture design for large enterprise

I am trying to create an integration layer between our client applications and external API's.
This integration layer is to be serverless and designed in Azure function.

I know when we are working with API there are numerous architecture to follow for example: micro services, n-tier etc....

When it comes to server less azure functions in .net core i am not able to find any architecture pattern to follow.
I fear when we have too many functions it will get too clumsy without any architecture defining our development.

For this question as an example let's say i have 10 azure functions in an eCommerce site:

3 for Order management
3 for Catalog management
3 for account management
And 1 for Promos

Now how can i group all these 10 functions in my visual studio.

  1. Should i create one big project and add all these functions inside the project/solution?
  2. Should i create 4 separate projects
  3. And lastly should i have again a separate project for my models, as i would be having lot of model classes?

Please help.

You could leverage domain analysis to model your microservices. Based on this, you would have 4 microservices (function apps in this case) - one each for order, catalog, account, and promos.

You can read more about Building Microservices on Azure in the Azure Architecture Center docs.

Coming to your questions on code structure, a single solution with projects for each microservice and a common project for shared code would be ideal. So, a total of five projects, at the least.

This approach would enable code reuse as required between the function apps. And for a single entry point, you could front your function apps with Azure APIM.
