@ggonong Thanks for reaching out. Yes, your understanding is correct as you are using both Built-In and Azure actions that may be connected to some resource.
The connections that you create using built-in operations are called built-in connections, or service provider connections. Built-in operations and their connections run locally in the same process that runs your workflows. Both are hosted on the redesigned Logic Apps runtime. In contrast, managed connections, or API connections, are created and run separately as Azure resources, which you deploy using ARM templates. As a result, built-in operations and their connections provide better performance due to their proximity to your workflows. This design also works well with deployment pipelines because the service provider connections are packaged into the same build artifact.
