Public vs Private vs Hybrid Cloud
Definition
The three deployment models for cloud resources. Public (shared infrastructure via internet), Private (infrastructure solely for one organization), and Hybrid (a mix of both).
Explain Like I'm New
Public is taking a city bus (shared by everyone, cheap). Private is owning a car (yours alone, expensive). Hybrid is driving your car to the bus station (using both securely).
Real World Example
A highly-regulated Bank uses a Hybrid Cloud. They keep all sensitive customer financial data on a Private Cloud (servers locked in their own basement), but run their public-facing marketing website on a Public Cloud (AWS) to handle massive web traffic.
