Third party hosted private clouds potentially alleviate these, as companies will not be required to make upfront capital expenses for hardware, nor need to have on-site personnel to run and maintain the hardware. Private Cloud. The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. When running a private cloud on-premises, companies have more visibility and control over the physical security controls and data storage. Public Cloud is by far the most common deployment model.
