A dedicated hosting service, dedicated server or managed hosting service is a type of Internet hosting where the client rents an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server (s), including choice of operating system, hardware, administration, etc. Server can be provided by the hosting company as an additional service. In some cases a dedicated server can offer less overhead and greater return on investment. Dedicated servers are most often housed in data centers, similar to placement services, which provide redundant power and HVAC systems. In contrast to the placement, the server hardware is owned by the supplier and, in some cases, provide support for your operating system or applications.
