Cloud Deployment Model defines the type of access to the cloud, i.e., how the cloud is located?

Cloud can be access in 4 types:

1. Public Cloud:
   Public cloud allows system and services to be easily accessible to general public. Public cloud could also be less secure attributable to its openness e.g. Email
2. Private Cloud:
   Private cloud allows systems and services to be accessible within an organisation.It offers accrued security attributable to its personal nature.
3. Community Cloud:
   Community cloud allows system and services to be accessible by group of organisation.
4. Hybrid Cloud:
   Hybrid cloud is a mixture of private and public cloud. However, the critical activities are performed using private cloud while non critical activities are performed using public cloud.

  Processing time and hardware requirements are reduced as well as elasticity enabled for future expansion.
• In Astronomic data processing:
  Energy costs and hardware requirements are reduced.Administration is simplified.
• In Central Government:
  IT expertise consolidate and hardware requirements are reduced.
• In Local Government:
  IT expertise consolidate and hardware requirements are reduced.
