The power apps portal is a web site that you can use to surface apps as web pages. A canvas app or a model driven app.
That license typically comes with dynamics, so if you have the license, chances are you have this p2 license.
Model driven apps vs canvas apps. More precisely, this refers to the data saved in common data service (cds). Start by designing your user experience on the power apps canvas. Default modern list template only available which can be further customized:
Powerapps for office is another plan that can only do. Sharepoint permissions on the list: More than 200 connectors available to connect with underlying data sources
Full control over every single aspect: While model apps are controlled more by the data and operational workflow. However, they provide a distinct and defined business process which users must follow and allow users to harvest the full potential of cds.
Integrating canvas apps using the modern app designer (preview) The p1 plan is for canvas applications. Canvas apps uses a powerpoint like user interface and excel formulas for configuration.
While developing a canvas app, you get full control over every aspect of the final product. The common data service has inherited the dynamics 365 customer engagement web services. It automatically generates forms and views for you from the existing data source using common data service to model forms.
When implemented with this method, a canvas app looks a lot like native apps you would use on your mobile devices currently. And the app will be responsive across devices. You don't have the same level of control over the look of the user interface that you do in a canvas app.
A model driven app is more stylized and is based on data that is stored in the common data service (cds). So if you want to generate a form from existing data and no need to make maker changes this will be the best choice. The p1 plan gives you access to premium connectors, one being the common data services.
There are two main app types that you can create using powerapps: The design and interface of canvas apps is completely under your control. As an example, into a dynamics 365 form.
Controlled by data and information provided: The deployment process is smooth, and users are notified when updates are available.
