The virtual infrastructure of the Consolidated SDDC consists of a single region with a consolidated cluster.

Figure 1. Consolidated Cluster  Logical Design

A Consolidated SDDC design contains one availability zone and has one distributed switch. The switch is connected to the management applications in the SDDC, the NSX components, and tenant workloads.

Consolidated Cluster

The consolidated cluster runs the virtual machines that manage the Consolidated SDDC. The management components include vCenter Server, vSphere Update Manager, NSX components, vRealize Operations Manager, vRealize Log Insight, vRealize Automation, vRealize Business for Cloud, and other shared management components.

All management, monitoring, and infrastructure services are provisioned to the consolidated vSphere cluster which provides high availability for these critical services.

NSX services enable North-South routing between the SDDC and the external network, and east-west routing inside the SDDC.

The consolidated cluster also hosts the SDDC tenant workloads. Workloads run customer business applications that have varying SLAs.
