With the standard architecture model, management workloads run on a dedicated management domain and user workloads are deployed in separate virtual infrastructure (VI) workload domains. Each workload domain is managed by a separate vCenter Server instance which provides for scalability and allows for autonomous licensing and lifecycle management.

Figure 1. Sample Standard Architecture

Standard architecture is the recommended model as it aligns with the VMware best practice of separating management workloads from customer workloads. It provides better long term flexibility and expansion options.
