What are the differences between FusionCompute and OpenStack KVM?

Hello, everyone!

Brief Analysis

Similar points: The hypervisor is the same, and both are KVM.

The main differences are as follows:

1. FusionCompute uses two VRMs (active and standby) to schedule and manage computing, storage, and network virtualization resources in a virtual resource pool.

2. FusionCloud (HUAWEI CLOUD Stack) uses FusionSphere OpenStack (NOVA, Cinder, Glance, and Neutron) to schedule and manage computing, storage, and network resources. On the FusionSphere OpenStack, the cloud service (Cloud service layer) layer and CMP layer (ManageOne) are used to implement multi-tenant, VDC, metering, approval management, and IaaS cloud service automation (ECS VM, EVS virtual disk, VPC network, and VFW VM firewall).

Brief Scenario Analysis

1. If the scale is small, for example, several servers, dozens of servers, or dozens of servers, and no (or weak) tenant, cloud service, or self-service application, the lightweight virtualization solution FusionCompute is used.

2. If there are dozens of servers or more, and cloud requirements such as multi-tenant /VDC, cloud service, and hybrid cloud are required, or if you want to (or prepare for PaaS and big data), you are advised to use FusionCloud (HUAWEI CLOUD Stack).

Hope this helps!
