Complex managed hosting, applies to both physical dedicated servers and virtual servers, with many companies choosing a hybrid (a combination of physical and virtual) hosting solution. There are many similarities between standard and complex managed hosting but the key difference is the level of administrative and engineering support that the customer pays for – owing to both the increased size and complexity of the infrastructure deployment. The provider steps in to take over most of the management, including security, memory, storage, and IT support. The service is primarily proactive. [1]
Dedicated hosting service, also called managed to host service, where the hosting service provider owns and manages the machine, leasing full control to the client. Management of the server can include monitoring to ensure the server continues to work effectively, backup services, installation of security patches, and various levels of technical support.
