Windows Server 2022 External Connector License requirements / Use case 1 & 2

Question

Hi,

in order to clear up this Ext. Connector understanding, here are two use cases:

1. Webshop
   

how many EC licences are required and where they need to applied if for examle this API on Windows server and MSSQL servers are on Vmware cluster?

2. B2B or B2C portal
   

same question goes here as well
Thank you.
