Term
| How does cloud provide Self-Service capabilities? |
|
Definition
| Consumers can provision and manage servers, systems, and resources through a single portal or developer API. For netapp, there is On-Demand which shows what resources are available to the consumer. |

Term
| How does shared resources help with maximum efficiency in a cloud environment? |
|
Definition
| Because resources are pooled there is a lot of load balancing. Resources can be allocated based on demand. |
|
|
Term
| How is the cloud elastic? |
|
Definition
| You can add or subtract host nodes seamlessly based on demand. |
|
|
Term
| What is measured metered in a cloud environment? |
