Tencent distributed cloud solution can provide a complete IaaS (including compute, storage, and network) with a minimum scale of 8 devices, including 3 for networking (primary and secondary), 3 for storage (3 replicas), and 2 for computing (primary and secondary). This environment already includes a high level of availability.
Tencent distributed cloud solution offers a minimal scale solution of just 3 servers. In this scenario, 2 devices are deployed as gateways to facilitate network virtualization, while 1 device serves as the host for VMs to provide compute virtualization capabilities. This solution can provide services in Cloud Dedicated Clusters (CDCs) and Tencent Cloud Edge Zones (TEZs).
In the 3-device solution, only compute virtualization and network virtualization are provided. storage virtualization is not included, but local disks are available for use.
The solution with 3 devices provides the same CMP capabilities as the solution with 8 fully configured IaaS devices and provides services through the Tencent Cloud console. The primary distinction between the two solutions lies in the support of storage virtualization service.
