Hi @skolisetti
1. Performance of the portal app:
Please look at the below thread. There is an inbuilt tool available, In addition, you can find some deep-dive info
https://powerusers.microsoft.com/t5/Power-Apps-Portals/Power-Apps-Portal-Performance-Load-Stress-test/td-p/830955#M5953
is there any way to test performance with load testing of virtual users? Answer: I am not aware of anything for this scenario.
2. How versioning will work in Portal apps ? Can 2 users work on the same page simultaneously ?
Versioning is not integrated directly as of now. You can configure CI/CD pipeline with ALM if needed. But many users are allowed to work on the same page. There are many threads in the same forum to see how large development teams are managing.
3. And is there any limit of users accessing the Portal app (website) ? Ex: like how many users can access the website
There is no limit, as this is a web app hosted in Azure, load balancing is taken care of Azure. If you are planning for a large user base like e-commerce, you may need to raise a ticket with Microsoft to see the possibilities. Otherwise Power Apps Portal can accommodate maximum users.
Hope it helps.
