Microsoft Teams App Deployment

Hi,

In the mentioned article, it states that it is possible to host the app via other cloud options besides Microsoft Azure.

Cloud-hosted
You can use any externally addressable service to host your development and production code and their HTTPS endpoints. There's no expectation that your capabilities reside on the same service. We require all domains to be accessed from your Teams apps listed in the [validDomains](https://learn.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema#validdomains) object in the manifest.json file.

However, the valid domains is a list/array of urls. If you provide multiple urls, how will the Teams application know which url contains the app logic?

This article also mentions that it is possible to host on custom cloud but doesn't give any more specifics: https://learn.microsoft.com/en-us/answers/questions/1358947/can-i-host-my-bot-on-my-own-servers

Can a more detailed explanation of how to host on a cloud service/server besides Azure be given?

Hi @BrianShao1, the validDomains array in the manifest.json file is used to specify the domains that your Microsoft Teams app is allowed to communicate with. However, it does not determine which URL contains the app logic.

[BrianShao1]

Okay, I understand. So now that validDomains is out of the question, how can I deploy an app to Microsoft Teams while hosting the app logic and storage on prem or in house cloud? In theory, I would only need to point the app to an endpoint right but where would I set that? Thanks for taking the time to review my case and reply to my questions.
