The private cloud concept is running the cloud software architecture and, possibly specialized hardware, within a companies’ own facilities and support by the customer’s own employees, rather than having it hosted from a data center operated by commercial providers like Amazon, IBM Microsoft, or Oracle.
A companies’ private (internal) cloud may be a one or more of these patterns and may be part of a larger hybrid-cloud strategy.
- Home-Grown, where the company has built its own software and or hardware could infrastructure where the private could is managed entirely by the companies’ resources.
- Commercial-Off-The-Self (COTS), where the cloud software and or hardware is purchased from a commercial vendor and install in the companies promises where is it is primarily managed by the companies’ resources with licensed technical support from the vendor.
- Appliance-Centric, where vendor specialty hardware and software are pre-assembled and pre-optimized, usually on proprietary databases to support a specific cloud strategic.
- Hybrid-Cloud, which may use some or all of the about approaches and have added components such as:
- Virtualization software to integrate, private-cloud, public-cloud, and non-cloud information resources into a central delivery architecture.
- Public/Private cloud where proprietary and customer sensitive information is kept on promise and less sensitive information is housed in one or more public clouds. The Public/Private hybrid-cloud strategy can also be provision temporary short duration increases in computational resources or where application and information development occur in the private cloud and migrated to a public cloud for productionalization.
In the modern technological era, there are a variety of cloud patterns, but this explanation highlights the major aspects of the private cloud concept which should clarify and assist in strategizing for your enterprise cloud.
