Virtual Server Management
The VPS Hosting is unmanaged hosting. The customer has allowed full management of the guest operating system. Loading software, patching, backups, and such would be handled by the customer.
The VPS can be accessed via Terminal Services - Remote Desktop. There is only allowed access for management with administrative rights.
The customer also can install a control panel on the guest to manage the hosting environment on the VPS.
From an end-customer perspective, a VPS looks and feels like a dedicated server, where patching, software loading, and so forth do not affect other guests on the server.
