This image shows a future deployment of the ChainSys data management architecture on Oracle Cloud Infrastructure (OCI).

The OCI region includes 1 virtual cloud network (VCN) that spans 3 fault domains. The region provides the following services:

The VCN includes the following gateways:

Internet gateway: Paired with a Oracle Cloud Infrastructure Web Application Firewall, it provides access to OCI for data source systems from on-premises or third-party cloud systems access.
Dynamic routing gateway (DRG): Provides private connectivity between on-premises networks and VCNs by using Site-to-Site VPN connected to the DRG. In this case, target systems in public clouds, private clouds, or on premises access OCI through the DRG.

The VCN provides 3 subnets:

Public subnet: Incoming traffic is handled by a load balancer in fault domain 1 and is then sent to Oracle Container Engine for Kubernetes (OKE) with a node pool in fault domain 1, web node, Collaborator, Publisher, and file storage resources in fault domain 2, and OKE autoscaling in fault domain 3.
Private subnet: Incoming traffic is handled by a load balancer in fault domain 1 and is then to Oracle Container Engine for Kubernetes (OKE) with a node pool in fault domain 1, data integration and migration, data cataloging, bots, analytics and visualization, app building, caching, scheduling, and data management in fault domain 2, and OKE autoscaling in fault domain 3.
Private subnet: Provides active and standby Oracle Autonomous JSON Database instances connected by Oracle Data Guard: Meta DB in fault domain 1, Datamart and Solr in fault domain 2, and Couch DB2 in fault domain 3.
