Guangxi Vocational and Technical College of Finance: four "must kill skills" to draw a new map of education desktop cloud! What do you think of when you mention Nanning? It is the pearl of southern Xinjiang with half the city green trees and half the city towers, and it is also the place that the folk songs of the world love; It is an important hub of the country's "Belt and Road", or a city card of China for ASEAN countries. Many people do not know that in Nanning, where there are many colleges and universities, there is a college called "the cradle of Guangxi financial talents" - Guangxi Financial Vocational and Technical College hidden by the Yongjiang River. As the only higher vocational education institution in Guangxi that cultivates financial and economic talents, it not only witnessed the changes of the times in Guangxi's economy, but also served as a model for promoting education informatization reform and cultivating innovative financial talents in the digital economy era under the background of Internet+education.

The Accounting Department is a key major in the informatization reform of Guangxi Vocational and Technical College of Finance. In order to improve the teaching quality, Guangxi Vocational and Technical College of Finance has set up a special training room and professional computer room for the accounting department. There are 17 professional computer rooms. In view of the particularity of accounting teaching, computer rooms need to support accounting related teaching software such as UFIDA, Kingdee, IBM, and accounting computerization, so as to realize the combination of daily theoretical teaching and practice. The use of specialized software and the increase in the number of PC terminals have brought new challenges to Guangxi Institute of Finance and Technology:

• There are many PC end parts, and the failure rate is high; The deployment, upgrade and troubleshooting of the teaching desktop system are time-consuming and labor-intensive;

• The number of PC terminals is large, and the PC in the computer room is public equipment, so the security risk of the intranet is large;

• The traditional decentralized management can not meet the evolving needs of advanced IT teaching.

Guangxi Institute of Finance and Technology has decided to use desktop cloud solutions instead of traditional PC solutions to build an intelligent accounting training room based on its current use of PCs for office and teaching and the need for simple operation and maintenance. After multiple investigations and comparative tests, the mobile cloud one-stop desktop cloud solution was finally selected.

Open a new mode of desktop cloud education in the training room

Since 2016, Guangxi Institute of Finance and Technology has started to purchase desktop cloud equipment; So far, more than 800 desktop clouds have been deployed. The desktop cloud solution will integrate the mobile cloud desktop cloud all-in-one machine with server, storage and other functions, and will be centrally deployed in the computer room of the school information center. More than 800 delicate and compact desktop cloud terminals will be distributed in the computer room training room as required. Through the simple and understandable graphical Web interface control platform, the unified management and operation and maintenance of the school cloud desktop will be realized.

At the same time, in view of the college's demand for high security assurance of teaching data, mobile cloud stores the local desktop and teaching data of traditional PCs in the cloud data center, and ensures the ultimate security of data through the end-to-end visualization and fine security management and control strategy of "cloud network end".

At present, when taking the 1+X exam, the regional accounting and financial skills contest and other examinations, the College distributes exam desktops and materials through the desktop cloud, which greatly improves the response speed. In addition, desktop, data, applications, etc. are all stored in the cloud, which not only solves the problem of difficult configuration of the traditional PC scene examination environment, but also greatly improves the security of teaching documents and examination information.

Four "must kill skills" to promote the upgrading of new education infrastructure

Mobile Cloud has brought four "must kill skills" to the cloud on the desktop of Guangxi Institute of Finance and Technology:

• Exclusive desktop safe travel

Through VDI desktop cloud technology, teachers and students can log in to their personal desktop through their accounts at any place to achieve personal data and desktop portability; Provide a variety of access authentication strategies, and combine distributed firewall, terminal security control, application control, peripheral control, transmission encryption, data theft, personal disk encryption and other measures to ensure desktop security.

• Dynamic deployment of resources on demand

Based on super fusion technology, server cluster, virtual machine migration, distributed storage, port aggregation are used to meet the decoupling of underlying resources and heterogeneous compatibility; Provide comprehensive data protection measures, such as image automatic/manual backup and recovery strategy, individual disk and data disk separate restore mechanism, and common user configurations of personal data (such as input method, favorites, Windows notes, etc.) are still retained after restarting the virtual machine to improve user office efficiency.

• Seamless scene compatibility and adaptation

Desktop cloud technology supports full scene coverage of the education industry, including peripheral compatible training rooms and software compatible training rooms; And through the WAN bandwidth link protocol developed by Mobile Cloud and the optimized VDI transmission protocol, the compatibility of a variety of large and medium-sized software and a variety of peripherals can be met to improve the user experience.

• Scenario fast switching, operation and maintenance simplification

With desktop cloud computing, the platform can be managed uniformly to improve management efficiency; Simplify operation and maintenance and reduce management difficulty by optimizing the number of operating system applications. Desktop cloud technology minimizes each operating system to ensure switching speed between courses; According to the exam scenes in some computer rooms, the second level switch of the mirror modules of different classes and exams is realized, which solves the problem of "every exam must last all night".

The director of the Information Center of Guangxi Institute of Finance and Technology said, "By creating a desktop cloud platform, the operation and maintenance management of desktop terminals has been simplified, and the efficiency of campus IT operation has been greatly improved. When software problems occur, the operation and maintenance engineers can solve problems only by remote processing, and no longer have to go to the training room site. In addition, hardware failures have also been greatly reduced. During the five years of use, only a few terminals have experienced failures, and they have been resolved in a timely manner. "
