Windows 365 Enterprise now supports Cloud PCs that are Azure AD joined. These devices can run in either:
• A Microsoft-hosted network:
◦ You don’t need to bring any Azure infrastructure
◦ You don't need to create an on-premises network connection.
• Your own network (using an on-premises network connection)
