Power Automate, also known as the new method of making workflows. This system automates business processes by utilising a large number of data sources.

Workflows
Every workflow contains a trigger that starts off a flow. Power Automate workflows usually run asynchronously making them much slower compared to Classic Workflows used in Dynamics 365. Workflows contain actions to do the doing. Regular Expressions can be added to actions for extra refinement. You find people usually use workflows to send automated emails and using it as part of app logic.
Actions
Actins perform functions such as getting and setting data around other services like SharePoint or Sales Force. There is an action for pretty much everything within Microsoft e.g. Get A File, Get File Contents, Update Row. Custom API actions are also allowed.
