When you design a VMware Cloud Foundation deployment, you decide what architecture model, that is, standard or consolidated, and what workload domain types, for example, consolidated, isolated, or standard, to implement according to the requirements for hardware, expected number of workloads and workload domains, co-location of management and customer workloads, identity isolation, and shared or isolated networking and security.
Architecture Models
Decide on a model according to your organization's requirements and your environment's resource capabilities. Implement a standard architecture for workload provisioning and mobility across VMware Cloud Foundation instances according to production best practices. If you plan to deploy a small-scale environment, or if you are working on an SDDC proof-of-concept, implement a consolidated architecture.
![The first decision is based on the need to minimize hardware. If yes, next if co-location of management and customer workloads is allowed, you implement the consolidated architecture. Otherwise, you implement the standard architecture.](images/GUID-0AA1DD09-C9E5-46BF-AEC4-E74D0A8AC9BD-high.png)

Use the standard architecture model of VMware Cloud Foundation. |

Requires additional hardware. |
Workload Domain Types
A workload domain represents a logical unit of application-ready infrastructure that groups ESXi hosts managed by a vCenter Server instance with specific characteristics according to VMware recommended practices. A workload domain can consist of one or more vSphere clusters, provisioned by SDDC Manager.

![The first decision is based on the architecture model. If you are not using the consolidated architecture, next if NSX must be shared between domains, you use VI workload domains. Otherwise, if you need more than 14 VI workload domains, you use isolated domains. Otherwise, you go with isolated workload domains if you need a dedicated single sign-on domain or with VI workload domains otherwise.](images/GUID-5F038D89-B35A-4694-8778-72A9F7DE21AC-high.png)
