This image shows a multicloud architecture featuring Oracle Cloud Infrastructure (OCI), Microsoft Azure, a third-party cloud with financial systems, and the internet used by Gas South customers.

Microsoft Azure provides a self-service portal for customers, an SQL database, Microsoft Business Intelligence, and an Attunity connector.

The OCI region has 1 availability domain and 1 VCN. The region has access to Oracle Utilities Customer Cloud Service (CCS) and its generalized data export (GDE). The region provides the following services:

• Oracle Cloud Infrastructure Backup and Restore
• Oracle Cloud Infrastructure Monitoring
• Oracle Cloud Infrastructure Object Storage
• Oracle Cloud Infrastructure Vault

The VCN provides the following gateways:

• Internet gateway: Provides communications between public subnets and internet hosts. In this architecture, it handles the communication traffic between OCI, Azure, and the financial systems cloud.
• Service gateway: VCNs communicate with services such as object storage over the Oracle network fabric without traversing the internet.

The VCN provides the following subnets:

• Load balancer public subnet: Provides load balancing for SOA integration traffic from the financial cloud and from Microsoft Business Intelligence and passes it to SOA managed servers in the SOA subnet.
• SOA private subnet: Provides Oracle SOA Cloud Service with virtual machine (VM) instances for managed file transfer (MFT), SOA Suite admin server, and multiple SOA Suite managed servers. Data from the managed servers is stored in a database in the database subnet.
• Database private subnet: Provides 2 Oracle Base Database Service instances: one for SOA data and one for staging GDE data. The staging database accepts data from object storage which originates from GDE. The Attunity connector pulls log change data from the staging database.
