I am doing POC with power apps portals and I am trying to understand the pros and cons as well as the limitations. Can someone help me please?
This is a pretty broad question, but at a high level Power Apps Portals allow you to quickly build web applications similar to a model-driven app, but expose it to users that don't have a Power Apps or Dynamics license. Most often Portals are meant for external users.
Power Apps Portals are meant for interacting with data stored in the Common Data Service (CDS), including Dynamics 365 Online. They don't leverage the connector framework that Power Automate or canvas-based Power Apps.
Feel free to post any specific questions and I'll do my best to help.
@nhayduk - Thank you for detailed answer. I've one quick follow up question - Can Portal handle 500 or more request submissions at the same time?
Broadly speaking the size of the Azure resources associated with your Power Apps Portals depends on how many logins you've associated it with. So from a technical standpoint, yes Portals can handle that many requests - just make sure you're licensing it appropriately.
The Portal will be public facing and for external users. They don't need license to access it. Am I correct? Before I publish I wanted to make sure that it will handle this load at the same time.
There was and I believe there still is an actual ('true') concurrent user limit (users doing actions at precisely the same instant) - but finding any documentation on it is nearly impossible.
