Deployment Models of Cloud Computing

Deployment Models of Cloud define the type of access to the cloud, i.e. how the cloud is located? There are 4 types of deployment models of cloud computing namely:

1. Public Cloud Model
2. Private Cloud Model
3. Community Cloud Model
4. Hybrid Cloud Model

Public Cloud Model:

The Public Cloud Model allows systems and services to be easily accessible to general public. Example: Google AppEngine, Amazon EC2.

Private Cloud Model:

The Private Cloud Model allows systems and services to be accessible within an organization. It is operated only within a single organization.
However, it may be managed internally or by third-party.

Community Cloud Model:

The Community Cloud Model allows systems and services to be accessible by a group of organizations. It shares the infrastructure between several organizations from a specific community.
It may be managed internally or by the third-party.

Hybrid Cloud Model:

The Hybrid Cloud Model is a mixture of Public Cloud and Private Cloud. Non-critical activities are performed using the public cloud while the critical activities are performed using private cloud.
