An internal cloud or private cloud is a specific type of cloud computing that involves a separate and secure cloud based environment for exclusive use of a specified client. Private clouds provide computing power as a service within a virtualized environment by using a cluster of physical computing resource which is only accessible by a single organization. A private cloud offers greater privacy as well as control. In contrast‚ an internal cloud has multiple clients accessing virtualized services drawing the resource they need from the same pool of servers across public networks.
An organization builds an internal cloud by utilizing the cloud computing service model and delivery framework. The private cloud then delivers computing, storage and software services to each node within the organization.
Internal cloud provides users the following key benefits:
•Gives you absolute control over security
•Cost of infrastructure is reduced
•Hardware needs are minimized
•Offers improved reliability
•Is both cost and energy efficient
An internal cloud is dedicated to only one user or organization and hence all it resources too are available to that user only. The single user will have the ability to configure the resources and manage it to match their unique needs. They can get a custom network solution that can provide them the desired results.
Internal cloud model can ensure better allocation of resources within an organization. This is done by making sure that resources are made available to individual departments according to their needs and demands. The flexibility that the internal cloud model brings to a business makes it cost effective as resources are not wasted and used highly efficiently. It is also possible to integrate private clouds with public cloud services to form hybrid clouds. Non-sensitive functions can be allocated to public cloud to maximize efficiency and performance.
