Library cloud desktop system cloud computing

Under the guidance of the "Ten-Year Development Plan for Educational Informatization (Year)", education departments and schools at all levels will increase investment in education platforms. The rise of cloud technology will also push education informatization to a new height.
The library (higher vocational school) cloud desktop system refers to the use of virtualization technology to share infrastructure, desktops, applications and other resources, and to centrally deploy and manage them, and to uniformly host them in the data center and deliver them as services. The desktop cloud system includes two parts: cloud terminal and cloud desktop platform. Based on the cloud desktop system, it is possible to access the personal desktop system through the cloud desktop access terminal.
Cloud desktop technology solutions include
, cloud terminal
Cloud terminal, also called thin terminal, is a small-sized, low-power access terminal device that provides users with input and output devices. The interface has functions such as network communication with the server. Cloud terminals usually use professional embedded processor chips with low power consumption and efficient operation, and install embedded operating systems.
, Cloud Desktop Platform
The cloud desktop platform mainly deploys desktop virtualization software on basic hardware through cloud computing technology, realizes the cloudification of basic hardware, and is responsible for the scheduling of the entire cloud desktop system, such as the new cloud desktop Registration and directing cloud desktop requests to available systems, providing unified b login interface services and communication capabilities with rear infrastructure, and providing unified management and on-demand allocation and deployment of computing resource pools, storage resource pools, and network resource pools , dynamic scheduling of resources, etc.
, Cloud resource pool construction plan
The cloud resource pool consists of underlying hardware resources and virtualization platform systems.
, underlying hardware resources
The underlying hardware resources include servers, storage, switches, etc.
Virtualization platform system
Functional structure of virtualization platform system
The virtualization platform uses the industry's mature open source as the virtualization engine and integrates carrier-grade server operating systems, virtualization management suites, and tool suites , providing comprehensive virtualization capability support for cloud computing solutions. Supports both full virtualization and paravirtualization modes, supports mainstream operating systems, supports d, BD, r, etc., supports multiple architectures such as RM, r, and MD and other hardware virtualization technologies. Provides functions such as high-availability clustering, online migration, dynamic load balancing, dynamic resource adjustment, and energy-saving management.
The virtualization platform provides configurable and graphical tools, supports (open virtual format),,,, and other image file formats, supports rapid creation and release, and can support D and standards.
_
The system includes H, host operating system, virtualization management center, log alarm component, service component, virtual network component, storage management component, high availability component, resource scheduling component, and virtual desktop components and energy management components, etc. The detailed functions of each module are as follows:
