Deployment Models
Where infrastructure lives. Combine these; most real estates are a mix.
| Model | Where | Trade-off |
|---|---|---|
| Public | All in the cloud | Least control of physical layer, most elasticity |
| Private | Your own infrastructure | Full control, full fixed costs |
| Hybrid Cloud | Cloud + on-premises, connected | Migration path; keep regulated workloads local |
| Multi | More than one cloud provider | Avoids lock-in; duplicate tooling and expertise |
- Multicloud (cloud + cloud) vs Hybrid Cloud (cloud + on-premises) vs multi-Region (one provider, many Regions).
