A product is considered cloud only if it meets the characteristics defined in
NIST SP 800-145.
Cloud services include:
- On-demand self-service
- Broad network access
- Resource pooling (multi-tenancy)
- Rapid elasticity
- Measured service
Examples of cloud: SaaS platforms, PaaS offerings, IaaS environments.
Not cloud: Dedicated hosted servers, managed appliances, staff-run enterprise systems.
If your product primarily relies on people and dedicated equipment rather than customer-controlled
scalable infrastructure, it is likely not cloud.
