IaaS and PaaS
The following table lists the Oracle Cloud service API endpoints that can be accessed from the private subnets in your VCN via a service gateway (SGW) or private service access (PSA). Please note that your applications may require access to public endpoints or services not supported by SGW or PSA. Be sure that you have a NAT gateway or other access to the internet if necessary.
Refer to the hyperlink for each service for more information about the service API and the regions where that service is supported.
SaaS
For all SaaS services, please work with your Oracle representative to inquire about private access.
