The functionality of a VPC depends on several critical networking layers that define how data flows and who can access it:
To understand a VPC, it is helpful to use the "apartment building" analogy. While a public cloud is like an apartment building where residents share common infrastructure, a VPC is akin to a private condominium within that building. You share the overall structure (the physical servers and hardware), but your unit is logically locked; no other resident can enter your space without explicit permission. This single-tenant experience on multi-tenant hardware provides the "best of both worlds": the massive resources of a provider like AWS or Google Cloud, but with your own private "walled garden".

: An Internet Gateway (IGW) acts as the door to the public internet for the VPC. Conversely, a NAT Gateway allows resources in a private subnet to reach out for updates without letting the internet "see" them directly.
