This image shows an Oracle Cloud Infrastructure (OCI) region with 1 availability domain, 1 virtual cloud network (VCN), and the following resources for the region:

• Oracle Cloud Infrastructure Identity and Access Management
• Audit
• Telemetry

The VCN provides the following additional gateways:

• Internet gateway: Provides communications between public subnets and remote users over the internet.
• Dynamic routing gateway (DRG): Provides private connectivity between on-premises networks and VCNs by using Site-to-Site VPN or FastConnect.

The VCN provides the following subnets, each with their own security list and route table.

• eCommerce (public subnet): Provides the eCommerce application which communicates with the Oracle MySQL Database Service.
• Database and analytics (private subnet): Provides Oracle Analytics Cloud (OAC) and a HeatWave cluster. A HeatWave cluster includes a MySQL System node and two or more HeatWave nodes. Both the eCommerce application and OAC connect to the MySQL node in the HeatWave cluster. OLTP transactions from the eCommerce application run in the MySQL node while OLAP queries from OAC run in HeatWave nodes for accelerated performance.
