- Connectivity and data-placement requirements
- Hybrid versus multicloud decision patterns
Overview
Cloud deployment models describe where resources run, who controls the underlying environment, and how separate environments are connected.
Core Concepts
- Public cloud uses provider-operated shared infrastructure with logical tenant isolation; customers retain responsibility for their workloads, identities, configurations, and data according to the service model.
- Private cloud is cloud infrastructure dedicated to a single organization; it may be owned, managed, and operated by the organization, a third party, or both.
- Hybrid cloud combines distinct private and public cloud environments with technology that enables data or application portability and coordinated operation.
Exam Tips
- Translate every requirement into a model characteristic before choosing.
- Be suspicious of answers using absolutes such as 'always cheaper,' 'always more secure,' or 'no vendor lock-in.'
