Orchestrating allocation of shared resources in a datacenter
A cluster configuration request to form a hyperconverged computing infrastructure (HCI) cluster in a cloud computing environment is processed. Based on the cluster configuration request and any other cluster specifications, a plurality of bare metal computing nodes of the cloud computing environment are configured to operate as an HCI cluster. First, a tenant-specific secure network overlay is formed on a first set of tenant-specific networking hardware resources. Then, the tenant-specific secure network overlay is used by an orchestrator to provision a second set of tenant-specific networking hardware resources. The second set of tenant-specific networking hardware resources are configured to interconnect node-local storage devices into a shared storage pool having a contiguous address space. Top-of-rack switches are configured to form a network overlay on the first set of tenant-specific networking hardware resources. Then, top-of-rack switches are configured to form a layer-2 subnet on the second set of tenant-specific networking hardware resources.
