This architecture shows a single Oracle Cloud
Infrastructure region with 1 availability domain and 1 virtual cloud network (VCN). The region provides the following services:
- Oracle
Analytics Cloud
- Oracle Cloud
Infrastructure compartments
- Oracle Cloud Infrastructure Identity
and Access Management
- Oracle Cloud
Infrastructure Object Storage
- Policies
The VCN provides a public subnet and a private subnet, each with their own security list and route table. The VCN provides
the following gateways:
- Internet gateway: Provides communications between public subnets and internet hosts or customer premises equipment.
- Dynamic routing gateway (DRG): Provides private connectivity between on-premises networks and VCNs by using Site-to-Site
VPN or FastConnect.
- Network address translation (NAT) gateway: Enables private resources in a VCN to access hosts on the internet, without exposing
those resources to incoming internet connections.
- Service gateway: VCNs communicate with services such as object storage over the Oracle network fabric without traversing the
internet.
The public subnet includes instances of Oracle Cloud
Infrastructure API Gateway and Oracle Cloud
Infrastructure Bastion.
The private subnet includes network security groups and an instance of Oracle Autonomous Database with autoscaling and private endpoint.
