Cloud computing offers us a means of accessing apps through the Internet as utilities. It enables internet apps to be created, configured, and customized. With Cloud, Computing users can access database resources from anywhere on the Internet for as long as they need without worrying about any actual resource maintenance or management.
The word cloud relates to the Internet or a network. We can tell, in other words, that cloud is present at a distant place. Cloud can provide services on a network basis, i.e., on government or private networks, i.e., WAN, LAN or VPN. Applications such as email, web conferencing, management of client relationships (CRM), all operate in the cloud.
Do deployment models identify the sort of cloud access, i.e., the location of the cloud? Cloud can have access to any of the four types: public, private, hybrid, and community.
PUBLIC CLOUD: The Public Cloud makes it easy for the public good to access systems and services. Due to its openness, e.g., e-mail, the public cloud may be less safe.
PRIVATE CLOUD : The Public Cloud makes it easy for the public good to access systems and services. Due to its openness, e.g., e-mail, the public cloud may be less safe.
COMMUNITY CLOUD : Community Cloud enables organizational groups to access systems and services.
HYBRID CLOUD : The Hybrid Cloud is a mixture of the private and public cloud. Critical operations are carried out using the personal cloud, however, while non-critical activities are carried out using government cloud.
