1. Different properties

　　OpenStack is a complete open source cloud computing platform that is maintained and developed by developers around the world. This allows users to use all the functions of OpenStack, and do not have to worry about the proprietary technical or functional restrictions that may exist; FusionCompute is a commercial cloud computing platform developed by Huawei. Users need to pay the corresponding licenses to use all functions.

　　2. Different architecture

　　OpenStack is a platform composed of multiple components. These components include computing, network, storage, identity authentication, mirror image, and so on. Each component can be configured and managed separately, so that the OpenStack platform can very flexibly meet different needs and scenes. FusionCompute is an integrated cloud computing platform. All functions are packaged together. Users cannot configure or manage each component alone.

　　3. Different community support

　　OpenStack has a huge global community, which is jointly maintained and developed by professionals from various organizations and industries. This allows OpenStack to be continuously updated and improved, and has been widely supported and applied. FusionCompute was independently developed and maintained by Huawei. Although Huawei also has certain technical strength and resources, its support and contributions to the global open source community are obviously limited.

　　4. Different compatibility

　　OpenStack is a very flexible and open cloud computing platform that can be used in combination with various hardware and software. FusionCompute is mainly optimized and adapted for Huawei's own hardware and software, and there may be some restrictions on the compatibility of other brands and systems.

　　5. Different ecological environment

　　Because OpenStack has a huge global community and rich component ecology, its ecological environment is very rich and diverse. Users can choose the most suitable components and tools according to their needs and scenes, and build the cloud computing platform that is most in line with their needs.

　　Overall, OpenStack and FusionCompute are open source software used to build and manage cloud computing platforms, but the difference between the two lies in open source nature, architecture, community support, compatibility and ecological environment. Users should choose the cloud computing platform that suits them according to their needs and actual situation.
