Abstract

Disclosed herein are a Desktop As A Service (DaaS) manager and DaaS client for a DaaS system. The DaaS manager includes a connection broker module, a provisioning module, a management module, and a web server module. The connection broker module permits connections to a DaaS client and a DaaS server to a user who has performed user authentication. The provisioning module determines the operating status of the DaaS server, and assigns a virtual machine of an optimum DaaS server to the DaaS client. The management module monitors the operating status of the DaaS server and the virtual machine, and executes a control command of the DaaS server. The web server module provides a web-based management tool Graphic User Interface (GUI) to the user.

Claims

1. A Desktop As A Service (DaaS) manager, comprising:

a connection broker module configured to permit connections to a DaaS client and a DaaS server to a user who has performed user authentication;

a provisioning module configured to determine operating status of the DaaS server, and to assign a virtual machine of an optimum DaaS server to the DaaS client;

a management module configured to monitor operating status of the DaaS server and the virtual machine, and to execute a control command of the DaaS server; and

a web server module configured to provide a web-based management tool Graphic User Interface (GUI) to the user.

2. The DaaS manager of claim 1, wherein the connection broker module permits assignment of a virtual machine only to a user that has connected through user authentication via virtual machine assignment request information of the user.

3. The DaaS manager of claim 2, wherein the connection broker module:

provides a desktop virtualization environment connection function and a screen redirection function using a remote connection protocol of the assigned virtual machine after the virtual machine has been assigned; and

in order for the user to connect again at a desired time when use of the assigned virtual machine is terminated, stores current environment settings based on the user'"'"'s account, and eliminates the desktop environment connection function and the screen redirection function.

4. The DaaS manager of claim 1, wherein the provisioning module assigns another virtual machine in real time when an abnormality occurs in the assigned virtual machine.

5. The DaaS manager of claim 1, wherein the provisioning module monitors resource assignment status and usage information of the DaaS server and use of generated virtual machines in real time, and assigns an optimum DaaS server.

6. The DaaS manager of claim 1, wherein the provisioning module separates an image for operation of the virtual machine and a disk image for a user of the DaaS client, and assigns the DaaS server thereto.

7. A DaaS client, comprising:

a hypervisor configured to accommodate one or more virtual machines above hardware;

a monitoring information collector configured to monitor the virtual machine;

a hardware profile collector configured to collect hardware information and Operating System (OS) level information of the DaaS client; and

a performance measurer configured to compute performance information of the virtual machine using information monitored by the monitoring information collector.

8. The DaaS client of claim 7, further comprising a command execution unit configured to buffer and execute a control command transferred from a virtualization server.
