actually Oracle Public Cloud has two different offerings, i.e. Bare Metal vs Virtual Machine.
The following excerpt from Oracle FAQ gives you the differences:
Bare Metal Instances - A bare metal instance is a physical server that is fully dedicated to you. [...]These instances offer over a million IOPS and are ideal for running any IO-intensive application or big data workload.
- Bare metal compute instances run only the software you choose, providing you with complete control. There is no Oracle-applied software on your instance.
- Bare metal compute instances have no hypervisor. You have the option to bring your own hypervisor. This makes it easy for you to migrate or extend your existing workload to the cloud as-is.
- Virtual Machine (VM) Instances - A VM compute instance is an isolated operating system environment on a multi-tenant host. You can provision VM and bare metal instances in your Virtual Cloud Network side-by-side and manage them using the same console and API.
This said, theoreticlly the Bare Metal Instances could make the job, and one could decide to make a pure test using an Oracle Bare Metal Instance, install VMWare on top of it, deploy the Delphix OVA, and unleash power of Delphix Data Platform to speed up data migration to Oracle Public Cloud.
May be you can investigate on using Oracle's Ravello Cloud Service to host your delphix engine VM.
Extract from public documentation
"With Oracle Ravello Cloud Service, you can deploy your existing VMware or KVM based data center workloads on any public cloud such as Oracle Cloud, Amazon Web Services (AWS), and Google Cloud, as-is, without any modification to the virtual machines, network, or storage."
