VPC-accessible only deployments

### What problem are you trying to solve?

I want "protected enclaves" where the JS code accessed via HTTP requests are only accessible within my company's VPC so that malicious external entities cannot access my resources.

### Describe the solution you'd like

A way to create deployments that aren't publicly accessible over HTTPS but require being connected to a virtual private cloud (Google, Amazon, etc.).

### Describe alternatives you've considered

Add layers of protection to publicly accessible endpoints via authentication and authorization strategies, however this sometimes does not security requirements by one's company or their partners.
