Apparatus and method for in-memory-based virtual desktop service

A virtual desktop service method, comprising:

• checking, by a connection manager, user profiles of a user terminal for the virtual desktop service and searching for a virtual machine suitable for hardware of the user terminal;
• requesting, by the connection manager, a virtual machine infrastructure to generate a corresponding virtual machine if the suitable virtual machine is not present and applying, by the connection broker, the user profiles to a corresponding virtual machine if the suitable virtual machine is present and generating a virtual desktop;
• and
• sending, by the connection manager, connection information for sending the generated virtual desktop to the user terminal and sending the virtual desktop to the user terminal using a delivery protocol of the virtual desktop,
• wherein the virtual machine infrastructure employs an in-memory virtual desktop which is created on a main memory,
• wherein the in-memory virtual desktop on the main memory is backed up as an image when a virtual desktop server is turned off,
• wherein the in-memory virtual desktop on the main memory is restored from a backup storage when the virtual desktop server is turned on,
• wherein the image is de-duplicated and is converted to a read or write command which is transferred in blocks on an accessible main memory address,
• wherein the resource pool performs a management function,
• wherein the management function classifies a type of users,
• wherein the user profiles are generated for the type of users, and environment information of a target hardware profile is pre-configured and shared with operating systems,
• wherein the management function provides the virtual desktop service by comparing physical hardware information with the previously-configured environment information,
• wherein the connection manager identifies an allocated user, a pooled user or a VM (multi-virtual machine) user,
• wherein the connection manager allocates a virtual machine by adopting a pre-set method and a manual method to the allocated user,
• wherein the connection manager allocates a non-persistent virtual machine for only one time use to the pooled user, and
• wherein the connection manager allocates multiple virtual machines to the VM (multi-virtual machine) user.
