Single-site OS Assisted Migration appliance: when HCX pairs a non-vSphere environment such as Hyper-V or KVM directly with vSphere, guests running Sentinel replicate to this appliance on the vSphere side.
Also called Sentinel Replication Gateway.

Terms in this definition
- OSAM
OS Assisted Migration: the VCF Operations HCX service that brings Linux and Windows guests over to vSphere from non-vSphere hypervisors like KVM and Hyper-V. Each guest gets the Sentinel agent and each site gets Sentinel appliances; at switchover the copy is adjusted and restarted, so the move is not outage-free.
- Azure Machine Learning environment
Versioned asset that pairs a Docker image with a pip or conda specification, so every job or deployment using it gets identical dependencies. You point to it by name plus a version number, or by name with @latest.
- Hyper-V
The hypervisor built into Windows. The VMs for the Azure Extended Network appliance require the Hyper-V role, using nested virtualisation, and an external virtual switch for each NIC.
- KVM
A hypervisor outside the vSphere family. Workloads on it, or on Hyper-V, can be moved by VCF Operations HCX through OS Assisted Migration, with a Sentinel agent installed in each guest.
- vSphere
VMware's platform for virtualisation, made up of vCenter and ESX hosts, supplying compute for VCF clusters.
