1. Difficulties in software environment deployment: There are a large number of computers and retrieval machines in the electronic reading room of the library, which are scattered. It is difficult to manage and maintain the software environment that needs to be updated frequently according to business requirements. At present, many software versions of the library computer system environment are relatively old.
2. Difficult management and control of reading rooms: Electronic reading rooms are usually connected to the Internet through campus networks, which provides convenience for students to obtain information and teachers to teach, but also provides a way for the spread of viruses. The number of computer room administrators is limited. In order to cope with the installation, maintenance, anti-virus and update of the system, the management and maintenance methods of the computer room must be improved to meet the challenges.
3, unable to provide a dedicated environment: students can not obtain a personal dedicated environment to meet the personalized needs of teaching experiments, homework, graduation design to save personal data.
4. PC users are not fixed: library users are highly mobile, the terminal software and hardware environment is easily destroyed, users have different computer usage habits and different needs, and the software environment on each computer needs to support various application needs.
5. High terminal energy consumption and high noise: the energy consumption of a traditional PC is not less than 250w W W. The more terminals, the greater the energy consumption, which does not meet the national call for green energy conservation, environmental protection and emission reduction. Moreover, PC terminals are noisy and cannot provide students with a quiet and comfortable reading environment.
6. High operation and maintenance cost: Due to frequent use of terminals and high failure rate, software deployment, update and patching all need the operation of IT management personnel. The deployment, testing and auditing of various PC configurations lack standardized and unified management, and technicians need to go to the fault site to deal with and solve problems, thus the overall operating cost is increasing.
This requires that the cloud desktop deployed by the school library can not only support the early business system, but also enable the terminal to realize standardized management and effectively prevent virus intrusion. In this way, higher requirements are put forward for the cloud desktop with the underlying architecture, because it is difficult to realize the cloud desktop with a single architecture if the above problems need to be solved at the lowest cost at one time. The next generation cloud desktop integrates the three mainstream architectures in the field of cloud desktop, and is a relatively solid cloud desktop at the bottom of the market. In terms of virus prevention, terminal patches and virus databases can be automatically upgraded regularly, and virus trojans can be automatically removed after the terminal system is restarted; Ensure the unified security reinforcement of the terminal system, and protect the terminal security through remote control, peripheral access control, arp firewall, flow control, full disk encryption, black and white process list and other functions. Because of the integration of IDV architecture, it can support the smooth migration of early business systems to new platforms in application scenarios such as libraries. In addition, the next generation cloud desktop supports unified image management, including template creation, template production, template update, policy setting, batch deployment and other functions. According to the requirements of teaching tasks, the mirror image of teaching desktop system and software environment can be created and distributed to all teaching terminals without installation and maintenance one by one. If there is a need for software installation and upgrade, the mirror template will be updated directly, and all terminals will be updated automatically without manual intervention, which greatly simplifies management and reduces the workload of operation and maintenance.
