Creating a Virtual Cloud Network

Before You Begin

This 30-minute tutorial shows you how to create a virtual cloud network (VCN) in Oracle Cloud Infrastructure.

Background

Before you can launch an instance, you need to have a VCN and subnet into which it can launch. A subnet is a subdivision of your VCN that you define in a single availability domain. For additional details, refer to Creating a Virtual Cloud Network and VCNs and Subnets.

What Do You Need?

• The user interface for the Oracle Cloud Infrastructure Console is constantly evolving. For the most up-to-date descriptions and navigation, refer to Using the Console.
• You should have a fundamental understanding of Oracle Cloud Infrastructure. It is highly recommended that you review the extensive collateral information, including training, at this site:

  Oracle Cloud Infrastructure

• You must have a subscription and an Administrator account to Oracle Cloud Infrastructure as described at this site:

  Getting Started with Oracle Cloud

• To access the Oracle Cloud Infrastructure Console, you must use a supported browser.

Creating a Virtual Cloud Network

To create a VCN on Oracle Cloud Infrastructure:

1. On the Oracle Cloud Infrastructure Console Home page, click the Navigation Menu in the upper-left corner.
   

   

2. From the Navigation Menu, in the Networking section, click to select the Virtual Cloud Networks service.
3. In the List Scope section in the left panel, use the COMPARTMENT drop-down to select the Compartment you created in the previous step.
4. Click the Create Virtual Cloud Network button.



5. On Create Virtual Cloud Network, complete the following fields:
   
   
   • CREATE IN COMPARTMENT
     Use the drop-down to select the Compartment you previously created and which will use this VCN.
   • NAME
     Enter a name for the VCN. In this example, the name given is: jde_vcn
6. Enable the CREATE VIRTUAL CLOUD NETWORK PLUS RELATED RESOURCES option:
7. Because the use of DNS is recommended, you should select the USE DNS HOSTNAMES IN THIS VCN check box.
   
   Note: The Domain Name System (DNS) lets computers use hostnames instead of IP addresses to communicate with each other. For additional details, refer to DNS in Your Virtual Cloud Network.
   
   Important: While on this form, you should also note the value given by the system for the field DNS Label. This value is required as input in the VCN DNS Label field in the Infrastructure Provisioning Console. If you do not provide a value for Name for the VCN, this value is auto-generated by the system. If you did provide a value for the Name for the VCN, the system eliminates special characters and limits the value to a maximum of 15 alphanumeric characters.
   

   

8. Click the Create Virtual Cloud Network button and verify that all VCN resource allocations are complete successfully.
9. On the Create Virtual Cloud Network screen that shows the VCN was successfully created, click the Close button.

   

10. On Virtual Cloud Networks in <name> Compartment, click the link for the VCN you just created. For example, jde_vcn.

    

11. Under Resources in the left pane, select Security Lists.
12. In the Security Lists in <vcn_name> section, click the link Default Security List for <vcn_name>.

    

13. On Default Security List for <vcn_name>, under resources, click the Ingress Rules resource in the left pane and then the Edit All Rules button.

    

14. On Allow Rules for Ingress, three default Stateful rules are displayed. You can accept the default rules and click the Edit All Rules button to add specific rules required for JD Edwards EnterpriseOne.

    

15. On Edit Security List Rules, in Allow Rules for Ingress, click the + Add Rule button.



16. To create additional rules that are required for JD Edwards EnterpriseOne One-Click Provisioning, click the Add Rule button.
    
    Because this VCN is only for the Infrastructure Staging Server, you only need to open port 5901 with a Source CIDR of 0.0.0.0/0. This is the listen port of the VNC Server.
17. For the new rule for the listen port of the VNC Server:
    
    SOURCE CIDR
    Enter this value: 0.0.0.0/0
    
    DESTINATION PORT RANGE
    Enter this value: 5901
18. Click the Save Security List Rules button to complete the setup for Ingress Rules. 
19. As shown below, you can accept the default Egress Stateful Rule that allows egress to all destinations, all protocols, and all traffic for all ports.
