The recommended way to connect to cloud environments is a secure and permanent network connection using a dedicated interconnect (such as AWS Direct Connect, Azure ExpressRoute, or Google Interconnect) for connecting from the on-premises to the cloud or using a site-to-site VPN (either from on-premises to the cloud or between cloud providers).
A secured and permanent connection will allow access control (layer 4 firewall rules) to be set between cloud providers and cloud segments and keep access to resources in the cloud (or allow access to cloud resources) for business needs.

- Which resources can be public (such as public API calls, frontend services, and VPN endpoints)?
- How will the network architecture adapt to changes (such...
