Basic Concepts of Cloud Computing
There are certain services and models working behind the scene making the cloud computing feasible and accessible to end users. Following are the working models for cloud computing:
Deployment Models
Service Models
Deployment Models
Deployment models define the type of access to the cloud, i.e., how the cloud is located? Cloud can have any of the four types of access: Public, Private, Hybrid, and Community.
Cloud Computing Deployment Models
PUBLIC CLOUD
The public cloud allows systems and services to be easily accessible to the general public. Public cloud may be less secure because of its openness.
PRIVATE CLOUD
The private cloud allows systems and services to be accessible within an organization. It is more secured because of its private nature.
COMMUNITY CLOUD
The community cloud allows systems and services to be accessible by a group of organizations.
HYBRID CLOUD
The hybrid cloud is a mixture of public and private cloud, in which the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
