Explain it_

InfrastructureHVMHVM (HPE VM Essentials virtualisation runtime) is the KVM-based virtualisation layer installed on physical hosts to run VMs.AI & Emerging TechnologyMLML (Machine learning) is the broad discipline of using data to develop systems that recognise patterns or make predictions.CybersecurityMicrosoft Entra IDMicrosoft Entra ID is the control plane for identity : who can sign in, what they can reach, and under what conditions.Backup & ResiliencePBSPBS (Proxmox Backup Server) is a separate backup application and datastore, not a setting that makes local storage into a backup.Cloud & HybridPrivate AIPrivate AI means AI workloads run in an environment dedicated to, and materially controlled by, the organisation.Backup & ResilienceRPORPO is the maximum acceptable data loss measured in time: an RPO of four hours means a restore may be up to four hours behind the failure.InfrastructureVEVE (Proxmox Virtual Environment) is an open-source virtualization platform based on KVM and LXC.
