Cloud Service Calculator

Answer the following questions to help determine if your IT resource meets the definition of a cloud service, based on the NIST Special Publication 800-145. A service must meet all five characteristics to be considered a cloud service.

1. On-Demand Self-Service: Can you create or scale the resources for this service (like storage or user accounts) on your own, without needing to contact a support person at the vendor?

Yes No

2. Broad Network Access: Can you use this service from any standard device like a laptop, phone, or tablet, as long as you have an internet connection (no proprietary software or VPN required)?

Yes No

3. Resource Pooling: Is this service hosted on infrastructure shared among multiple customers, rather than on hardware dedicated solely to you?

Yes No

4. Rapid Elasticity: Can this service automatically handle sudden spikes in usage (like many users logging on at once, or an increase in data) without slowing down or needing new licenses?

Yes No

5. Measured Service: Is the cost of this service based on how much you actually consume (pay-as-you-go), or is it a fixed price (like a yearly license) regardless of usage?

Yes, usage-based No, fixed price
