This profile is used to either archive the activity log to a storage account or stream it to an Azure event hub.

+In the activity logs events can pertain to a region or could be "Global". Global essentially means these events are region agnostics and are independent of region, in fact majority of events fall into this category. If the activity log profile is set from the portal, it implicitly adds "Global" along with any other region selected in the user interface. When using the cmdlet, the location as "Global" must be explicitly mentioned apart from any other region.
