What is Private Cloud?
A private cloud describes a cloud computing platform that involves a separate and secure cloud based environment where the hardware, storage and network can only be operated by one specified client. It delivers similar advantages to the public cloud including scalability and self-service, but also offers control over enterprise and customer data, diminishes worries around security and eliminates issues with regulatory compliance. Private clouds are a great solution for companies that rely on proven methods and who need control of their environment, but would benefit from hosted virtual machines rather than managing a data center.
A private cloud shares some of the benefits of a public cloud such as scalability and multi-tenancy. In addition is the ability to provision machines, on-demand change of computing resources and the creation of multiple machines for complex computing jobs. Besides the benefits previously mentioned, a private cloud offers a variety of features that a public cloud cannot, including:
- Improved Security: In a private cloud, data is tightly secured and controlled on servers that only the company has access to, ensuring that operations are kept out of the reach of others. It may be managed and maintained by an internal IT staff or held in a cloud service provider’s data center.
- Better Control: Only being accessible by a single organization, this cloud can be configured, managed and tailored to suit an organization’s own preference and style.
- Hybrid Deployments: It has the ability to integrate a dedicated server’s hardware when it is required to run a high speed database application, essentially combining the solution between virtual and dedicated servers.
- Flexibility: Offers “cloud bursting” functionality which comes into play during instances of spiked demand. Cloud bursting allows a provider to switch non-sensitive data to the public cloud to free up more space in the private cloud for sensitive data that may require the additional room.
- Increased Reliability:Offers enhanced and more predictable service availability for users, where the creation of virtualized operating environments makes the network more resilient to physical infrastructure failures.
- Cost and Energy Efficiency: Although not as cost efficient as a public cloud, a private cloud will minimize the investment into unused capacity which offers benefits pertaining to organization’s cost and energy use.
