Oracle Cloud Infrastructure (OCI) allows you to define your own data centre network topology inside the Oracle Cloud using a Virtual Cloud Network (VCN).

The screens change a little with each quarterly release of Oracle Cloud. Even so, the screen shots in this article will give you a good idea of what is involved.

A Virtual Cloud Network is made up of the following components.

This can sound a little confusing if you are not familiar with networking, but you can use defaults for most things, so you don't need to be a networking expert to try it out.

Log into the Oracle Cloud.

OCI Console

Use the top-left menu to select the "Networking > Virtual Cloud Networks" option.
