2.2.4 Network Setup

This topic describes the systematic instructions on network setup.

Setting up a network in Oracle Cloud Infrastructure (OCI) involves creating and configuring several components to ensure secure, reliable, and efficient connectivity for cloud resources.

Follow the steps below to setup the network:

  1. Ensure that the network configuration allows connectivity between the source and target environments.
  2. Create a VCN (Virtual Cloud Network) and subnet in the target tenancy if they are not already available.

  3. Select the Create VCN with Internet Connectivity option.
  4. Specify a VCN Name, accept all other defaults, and click Next.

  5. Review the resources and note the CIDR on the Subnet.
    User’s Target environment resources will be associated with the subnet.

  6. User can view all the resources that are built successfully.
  7. User can view the Virtual Cloud Network by following the process below:
    1. Copy and note the VCN’s OCID and name. This information is required for the Network Path Creation.
    2. Select the subnet where the user would like the Target environment resources to be located.
  8. Copy and note the Subnet’s OCID and name. This information is required for the Network Path Creation.
  9. Select the Default Security list associated with the subnet.

  10. User can add an Ingress Rule to the default Security list, using the Subnet CIDR noted above in Step 5. The rule must allow ingress of TCP on 443.

    Note:

    The Security Rule is prerequisite of the environment creation.
