Subnet

A subnet is a subdivision of a cloud network. Each subnet exists in a single availability domain and consists of a contiguous range of IP addresses that do not overlap with other subnets in the cloud network.

You can create your own subnet before you provision an Oracle SOA Cloud Service instance. See VCNs and Subnets in the Oracle Cloud Infrastructure documentation.

For convenience, if you do not explicitly select a subnet (No Preference), then the service instance is assigned to a subnet in the predefined Virtual Cloud Network (VCN) named svc-vcn, which is found in the compartment named ManagedCompartmentForPaaS. You cannot modify these predefined subnets, such as assigning a custom security list. If you prefer more control over the network configuration for your service instance, then create a custom subnet.

You must satisfy certain subnet and policy prerequisites when you create a subnet for use with Oracle SOA Cloud Service instances. See Prerequisites for Oracle Platform Services in the Oracle Cloud Infrastructure documentation.
