Private
- Private cloud (on-premises / virtualized data center)
- Cloud-style resource pooling and virtualization, but on infrastructure dedicated to one organization.
- Often called “on-premises” in exam wording. See on-premises.
- Why organizations choose it
- Regulatory or contractual requirements for physical control of data.
- Existing capital investment in hardware not yet depreciated.
- Legacy applications that cannot be moved.
- Trade-offs
- You carry the fixed costs: hardware, floor space, power, cooling, staff, refresh cycles.
- Capacity must be bought ahead of demand — no Elasticity.
- AWS options that fit this shape
- AWS Outposts — AWS hardware in your data center with cloud APIs.
- Contrast with
- Public — provider-owned. Hybrid Cloud — a mix.
