Public, private and hybrid cloud: comparison
Public cloud uses a provider platform shared across customers; private cloud is dedicated to one organization; hybrid cloud connects distinct environments. Evaluate applications, data, continuity, operations and total cost before choosing.
Compare workloads, not labels
Assess each workload separately. A new application with variable demand may have different constraints from a system that depends on local equipment. Document data, integration and recovery requirements first.
Compare total cost
Include infrastructure, licenses, connectivity, support and operator effort. Model expected usage and growth. Offers with different recovery capabilities should not be compared on monthly price alone.
Questions before migration
Which systems depend on the application? Who owns access and backups? How will restoration be tested? What happens if consumption changes? These answers help define a practical migration scope.
| Criterion | Public | Private | Hybrid |
|---|---|---|---|
| Infrastructure use | Provider platform shared across customers | Exclusive to one organization | Connected distinct environments |
| Operations | Shared responsibilities with the provider | Responsibilities agreed with the operator | Coordination across environments |
| Capacity | On-demand resources and services | Contracted or installed capacity | Capacity and integration of each environment |
| Evaluate | Usage, services, data and connectivity | Capacity, controls and operations | Integration, identity and observability |
