The ROBO SDDC consists of a consolidated pod in a ROBO location, and a hub that is responsible for provisioning workloads and monitoring the SDDC.
Management pods run the virtual machines that manage the SDDC in the hub. This includes the vRealize Automation and vRealize Operations components used for provisioning and monitoring all regions. For more information on the management pod see the VMware Validated Design for SDDC.
The consolidated pod runs the required SDDC components to manage ROBO workloads and send data back to the hub for analysis, as well as local backup and recovery. It hosts vCenter Server, NSX components, vRealize Operations Remote Collectors, vRealize Log Insight, vRealize Automation agents and other shared management components.
NSX services enable north-south routing between the SDDC and the external network, and east-west routing inside the SDDC.
The consolidated pod also hosts the SDDC tenant virtual machines (sometimes referred to as workloads or payloads). Workloads run customer business applications supporting varying SLAs. These workloads typically have low latency and security requirements for local deployment.
Should your ROBO site need to scale beyond a single pod (100 workloads), consider using the appropriate pod design to properly scale the solution based on the VMware Validated Design for SDDC.
