Abstract: Examples described herein include systems and methods for parallel upgrades of multiple hosts within an on-premises, multi-rack software-defined data center (“SDDC”). Upgrade instructions can be provided to a point-of-presence (“POP”) virtual machine (“VM”) of the SDDC, which can call an application programming interface (“API”) of a pod service executing on a control plane VM in the SDDC. For example, the pod service can generate a set of instructions for performing cluster upgrades in parallel. In one example, the pod service provides the instructions to a lifecycle management service executing on a VM of the SDDC, such as the control plane VM. In some examples, the lifecycle management service can add a spare host to a cluster of hosts in order to begin upgrading one or more hosts in that cluster. This can be performed in parallel, using the spare hosts from different racks simultaneously.
