In order to promote the deep integration of digital economy with the real economy and accelerate the digital transformation and upgrading of traditional industries, the Digital Economy Research Center of the People's Daily Financial Research Institute, in conjunction with the Cloud Computing and Big Data Research Institute of the China Academy of Information and Communications Research to launch the "Digital Creation New Entity - Digital Technology Empowers the Real Economy" project. The hybrid cloud management platform jointly created by China Agricultural University and Qingyun Technology was successfully selected as the "Digital Creation New Entity·2021-2022 Digital Technology Empowers the Real Economy Case Library".
"Resources one cloud" connects to campus
Focusing on the construction of a smart campus, China Agricultural University has proposed the "three managements, two constructions and one opening-up" strategy. Among them, the construction of "resource cloud" is an important part of the strategy, including information infrastructure such as servers and storage. Cloud technology provides stable, reliable and flexible information resources for various public service platforms of the school, business systems and websites of various units.
China Agricultural University has a total of 18 colleges, 1 physical teaching unit and 1 direct department, covering 7 major disciplines including agriculture, engineering, science, economics, management, law, literature, etc., and has undergraduate colleges, graduate schools, Continuing Education College and physical education teaching department.
Initially, various colleges, laboratories, directly affiliated institutions, and management departments would host the physical machines of the entity to the network information center as needed. A website may occupy several servers, which not only leads to waste of resources, but also occupies a lot of space. When the school used virtualization to solve resources, new problems arose again. The VMware clusters cannot form interconnection and unified management, and the effect of resource support is not satisfactory.
So, when planning a "resource cloud", seamless interconnection, data flow, unified management, and business load placement on demand have become important goals. The initial planned private cloud platform construction has gradually changed during the specific implementation process, and the important reason behind it is "people-oriented".
Under the clear demands of "maximizing computing resources", "safety and stability" and "operable", China Agricultural University chose QingCloud Enterprise Cloud to build a private cloud on campus, carrying high-concurrency systems such as big data training platform and one-card relationship system. In addition to the effective solution to the problem of resource shortage, the original process of applying for resources by teachers and the heads of various application systems was cumbersome and slow, but now it can be easily completed through automated delivery capabilities and self-service management capabilities.
"Nebula" platform shines brightly
On the basis of forming a unified fee and unified account management, the school network information center has also found new ideas in operation. Based on the unified architecture of Qingyun's public cloud and private cloud, China Agricultural University has decided to introduce public cloud to bring more convenience and vitality to the campus.
The first mixed cloud of universities in China - the "Nebula" platform was born like this.
"Nembroidery" platform mainly carries the following tasks:
The private cloud platform mainly carries on campus OA, one-card network and other on-campus information systems and some teaching and research projects. It is currently gradually migrating the existing business system from the virtualization platform to the private cloud platform, and ultimately realizes the agile deployment and operation of the business system in a cloud-based manner.
As the extension of the school's private cloud resource pool, the public cloud platform carries out external platforms for scientific research experiment testing of school teachers and students based on actual conditions, meeting the needs of agile resource acquisition and flexible resource expansion of scientific research and experimental projects.
Containing public and private clouds through a unified platform. Block the underlying differences, provide users with consistent access and usage experience, and at the same time connect to the on-campus CAS account system for permission control.
From a technical perspective, "Neiyun" has the following capabilities:
Build a hybrid cloud unified user portal portal portal, provide a resource service directory, for teachers and students to self-service application, use, and manage cloud resources, and realize the full life cycle management of resources of teachers and students, , creation, modification, deletion, and destruction of resources, etc.
Contribute to Qingyun private cloud, public cloud, and VMware multi-resource platforms to realize unified management and operation and maintenance of heterogeneous resource pools. At the same time, use a hybrid cloud management platform to block the underlying differences and provide users with consistent access and user experience.
Brand private cloud and public cloud VPC networks on campus through SD-WAN, realize network interoperability, build a campus hybrid cloud intranet, and unify network IP planning and control. The network-level strategy is still managed and controlled by the school, and the internal and external network interoperability strategies and access routes are formulated to ensure network control capabilities.
Hybrid cloud serving teachers and students across the school
With the overall migration of the virtualization platform, the school network information center uses a hybrid cloud platform to achieve real resource unity and management simplification.
The network-level strategy is still unified by the school to safely realize unified management, unified operation and unified operation and maintenance; resource applications are quickly approved through electronic processes, and finally the network technology center will allocate and use the resource pool.
QingCloud service team helps the school establish hybrid cloud resource management specifications through flexible custom form design and approval process design, ensuring that teachers and students can use cloud resources safely and conveniently and meet innovative needs.
"Neiyun" connects people, finance, materials, teaching, scientific research, office and management of China Agricultural University, allowing teachers and students to enjoy convenience and making campus management smarter.
For example, the campus portal - a comprehensive service platform, as the carrier platform of "one hall of service", provides more than 300 services to all teachers and students in the school, with a daily visit volume of up to 40,000 times. It is smoothly connected with more than 190 systems, realizing login with the account password of authentication with the unified identity of . At present, the comprehensive service platform has handled services in total 180,000 times, and teachers and students have 530,000 less errands.
"Less running errands" not only brings convenience to teachers and students, but also ensures safety during the epidemic period. The epidemic prevention and control platform covering the East Campus, West Campus and Yantai Research Institute of China Agricultural University is also supported by the "Neiyun" platform. The platform includes automated processing between 8 major systems and more than 100 devices, and the data volume reaches tens of millions.
In the future, China Agricultural University and Qingyun Technology will continue to explore in achieving more friendly mobile support and promoting cloud native landing, opening up more hybrid cloud service supply and management functions to all teachers and students in the school, so as to facilitate the opening, use and access to cloud services for all teachers and students in the school to improve the user experience of teachers and students, and allow digital innovation to truly serve every teacher and student.
