  • Define cloud models, including public, private, and hybrid.

    • Public cloud	Private cloud	Hybrid cloud
      No capital expenditures to scale up	Organizations have complete control over resources and security	Provides the most flexibility
      Applications can be quickly provisioned and deprovisioned	Data is not collocated with other organizations’ data	Organizations determine where to run their applications
      Organizations pay only for what they use	Hardware must be purchased for startup and maintenance	Organizations control security, compliance, or legal requirements
      Organizations don’t have complete control over resources and security	Organizations are responsible for hardware maintenance and updates
