As a first class citizen of Oracle Cloud Infrastructure, the network layers of the Oracle Cloud VMware Solution are interlinked with those of the parent OCI Virtual Cloud Network (VCN). Understanding how the networks of each layer relate to each other is important, but difficult to visualize, so, to help with that, here’s a Reference Architecture poster.
Because Oracle Cloud VMware Solution (OCVS) is a fully customer-managed implementation of the VMware Cloud Foundation stack, hosted on Oracle’s global Cloud Infrastructure platform, it’s arguably the Hyperscaler VMware offering which is most like your existing on-premises deployment. However, unless your on-prem deployment is on an “OCI Dedicated Region Cloud @ Customer” it’s unlikely that your network underlay is quite the same as the one underpinning OCVS. In this post we’ll see one of the ways this shows up, and how you can work around it.
