Solution Details
- Centralized remote Management
Designed for IT administrators, the platform features a B/S (Browser/Server) architecture with a graphical user interface accessible from any network-connected device. It enables unified management of VDI, VOI, and IDV desktop architectures, along with centralized control over physical servers, virtual machines, terminal devices, and storage systems.
- Pre-Deployment of Exam Environments
The platform supports pre-deployment of exam-specific environments (e.g., Windows 10, Windows 7) based on different exam requirements. Once an exam template is created, virtual machines with identical configurations can be cloned in batches and delivered quickly over the network. Multiple exam environments can be deployed simultaneously and hidden until needed, protecting system integrity in advance.
- High Compatibility with Exam Requirements
The platform allows batch generation or modification of VM parameters such as IP address, login username, and computer name to meet custom deployment requirements. It also supports on-demand configuration of desktop restore policies.
Additionally, a built-in screen watermark function is available for Windows environments, displaying details like computer name, terminal ID, desktop IP, and restore mode—making it easy for administrators to identify and maintain exam terminals.
- Fast Delivery and Recovery
Pre-deployed exam environments can be instantly delivered when needed using the platform’s one-click delivery feature. Students can log in and use the environment immediately. After the exam, the system can quickly reclaim and hide the desktops, preserving the original environment while freeing up system resources. There is no need to re-upload or replicate system images, and the system can seamlessly switch back to daily teaching desktops.
- Exam Environment Reliability and Safety
To avoid disruptions during examinations, the platform supports both master node HA and desktop-level HA. In case of server failure, virtual desktops are automatically migrated to other available servers without downtime.
If a terminal is unexpectedly powered off, data is retained upon reboot. In extreme scenarios, the platform supports dual-system fallback: even if virtualization fails, the system can switch to a local OS on the terminal, ensuring exams continue using local resources.
- Daily Teaching Support
When exams are not scheduled, the system can instantly switch back to daily training and teaching desktops. Virtual desktops with different OS environments—including Windows 7, Windows 10, Linux, and China’s Kylin OS—can be delivered based on course schedules. Each OS is isolated, with software installed on-demand, and desktops can auto-start based on the timetable.
- Student Behavior Control and Monitoring
The platform provides comprehensive behavior monitoring tools for both exams and classes. Features include:
Network access policies (e.g., block external or full network, allow list exceptions)
Application control and peripheral restrictions (USB, mobile storage, mobile device access)
Remote operations such as rebooting, waking, or shutting down terminals and desktops
These functions help ensure a safe and orderly digital teaching and testing environment.
- Compatibility and Scalability
The platform supports a wide range of systems, including Windows XP/7/10/Server 2012, Ubuntu, Red Hat, and domestic OS such as NeoKylin. It is compatible with various terminal architectures and form factors:
- x86/ARM-based thin clients
- All-in-one terminals
- VOI thick clients
- Legacy PCs and repurposed devices
It also supports a variety of exam systems, including National Computer Proficiency Exams, ATA Exams etc.
Solution Value
- Flexible Switching Between Exams and Daily Training
A unified cloud platform supports seamless switching across all application scenarios—including daily teaching, practical training, assessments, office work, standardized exams, ATA exams, medical and judicial exams, competitions, and online grading for college entrance exams—ensuring a consistent and efficient experience for both teachers and students.
- Simplifies IT O&M efficiency by up to 90%
A single cloud platform enables unified construction of economics and management computer labs. Through one centralized web-based management interface, desktops across all disciplines—such as International Economics and Trade, Business Administration, E-commerce, Financial Management, Logistics, and Finance—can be deployed, upgraded, and maintained at scale, covering thousands of desktops.
- Higher Resource Utilization, Future-Proof Scalability
Built on a cloud resource service model with high efficiency and scalability, the solution can support over 10,000 terminals and 100,000 desktops—meeting the demands of the next 5–10 years of IT development and educational expansion.
