Public
- Public cloud (cloud-native)
- Everything runs in the cloud provider’s infrastructure; no on-premises components.
- Applications are either migrated to the cloud or built there from the start.
- Characteristics
- No capital expenditure on hardware — fixed costs become variable costs.
- Provider owns and operates the physical layer; you consume it as a service.
- Immediate global reach through AWS Regions and Availability Zones.
- Trade-offs
- Least control over the physical layer.
- Data residency and latency to on-premises systems must be designed for.
- Contrast with
- Private — you own the infrastructure.
- Hybrid Cloud — both, connected together.
