PUBLIC CLOUD allows systems and services to be easily accessible to the general public. Public cloud may be less secured because of its openness, e.g. e-mail
PRIVATE CLOUD allows systems and services to be accessible within an organization. It offers increased security because of its private nature.
COMMUNITY CLOUD allows systems and services to be accessible by group of organizations.
