What type of access do Service Gateways provide from VCNs to Oracle Services?

Service Gateways facilitate private connectivity from Virtual Cloud Networks (VCNs) to Oracle Services. This means that traffic between the VCN and Oracle services does not traverse the public internet, ensuring improved security and reduced latency. By utilizing Service Gateways, organizations can maintain data privacy and comply with security policies while accessing Oracle Cloud services like Oracle Object Storage, Oracle Autonomous Database, and others.

In this design, the connectivity is achieved over Oracle Cloud's backbone network, which further enhances performance and reliability. This model is key in multicloud architectures, where secure and efficient communication between services is paramount. Therefore, the term "private" accurately describes the type of access provided by Service Gateways to Oracle Services, as it does not involve any public IP addresses or expose data to the open internet.
