Hello, everyone!
Today we can talk about Huawei FusionAccess campus cloud classroom solution.
The Huawei and Mythware cloud classroom solution (cloud classroom solution for short) is a desktop cloud solution designed for electronic classrooms. This solution consists of Huawei FusionAccess and Mythware teaching software.
Students' desktops use linked clone VMs to meet rapid VM concurrent start and restoration requirements. Full copy VMs are recommended for teachers' desktops. Students' and teachers' VMs are all deployed on the cloud. You are advised to use the Windows 7 SP1 (32-bit or 64-bit) operating system.
Mythware teaching software provides various teaching functions, such as screen broadcast, Internet cinema, and demonstration to assist teachers in giving live and vivid lessons.
The cloud classroom solution supports multiple-classroom deployment (single campus and multiple campuses), and can be integrated with teacher OA and multimedia teaching scenarios to form a cloud with one access ingress. The cloud classroom solution also supports single-classroom deployment and meets requirements in different scenarios.
Multiple-Campus Centralized Deployment
Multiple-campus centralized deployment: Cloud classroom desktop components are deployed in the district/county education bureau. Schools directly use the desktops. This deployment mode is applicable to scenarios where schools require unified management of resources.
The deployment mode enables unified management of resources and resource sharing. One cloud meets the access requirements of all scenarios and schools.
Single-Campus Deployment
Single-campus deployment: All cloud classroom desktop components are deployed in the equipment room and access terminals are deployed in classrooms. This deployment mode applies to cloud classes in schools that have independent equipment rooms and require deployment expansion in the future.
This deployment mode features high reliability and scalability. The disadvantage is that the school network quality must meet certain requirements.
The active/standby deployment scheme with high system reliability is recommended in the cloud classroom solution.
For multiple-campus deployment of the cloud classroom solution, multiple sets of FusionAccess systems (HDC+WI+GaussDB) are recommended with consideration to high concurrency. The deployment schemes are as follows:
When the number of users exceeds 1000, and the ITA and License are available, add multiple sets of FusionAccess systems (GaussDB+HDC+WI) on a basis of 1000 users. For example, if the number of users is 2500, you can deploy three sets of FusionAccess systems (one set involves ITA+GaussDB+HDC+WI+License and the other two involve only HDC+WI+GaussDB).
