Create Your VCN

Summary

Note: Some of the UIs might look a little different than the screen shots included in the instructions, but you can still use the instructions to complete the hands-on labs.

Overview

Oracle Cloud Infrastructure Compute lets you create multiple Virtual Cloud Networks (VCNs). These VCNs will contain the security lists, compute instances, load balancers and many other types of network assets.

Be sure to review Overview of Networking to gain a full understanding of the network components and their relationships.

Pre-Requisites

To sign in to the Console, you need the following:

  3. Complete the following fields:

    Field Vaue
    VCN NAME OCI_HOL_VCN
    COMPARTMENT Choose the Demo compartment you created in the Identity Lab
    VCN CIDR BLOCK 10.0.0.0/16
    PUBLIC SUNBET CIDR BLOCK 10.0.2.0/24
    PRIVATE SUBNET CIDR BLOCK 10.0.1.0/24
    USE DNS HOSTNAMES IN THIS VCN Checked

    Your screen should look similar to the following:

  4. Press the Next button at the bottom of the screen.

  5. Review your settings to be sure they are correct. Review CV Configuration

  7. Once you see that the creation is complete (see previous screenshot), click on the View Virtual Cloud Network button.

Summary

This VCN will contain all of the other assets that you will create during this set of labs. In real-world situations, you would crete multiple VCNs based on their need for access (which ports to open) and who can access them. Both of these concepts are covered in the next lab Compute
