Application Firewall (WAF)
- Policies
The VCN provides the following gateways:
- Internet gateway: Provides communications between public subnets and internet hosts. Internet devices and users communicate
with OCI by using application programming interfaces (APIs) over a web application firewall (WAF) and an internet gateway.
Supported APIs include drone service API, delivery service API, enclosure API over cellular, and user mobile app API.
- Service gateway: VCNs communicate with services such as object storage over the Oracle network fabric without traversing the
internet.
The VCN includes the following subnets:
- Load balancer public subnet: Provides a primary load balancer in fault domain 1 and a standby load balancer in fault domain
2. The load balancers accept traffic from the internet that comes through the WAF and the internet gateway.
- Server private subnet: Provides an Oracle Cloud Infrastructure Container
Engine for Kubernetes (OKE) cluster with instances of the Mosquitto (MQTT) broker and node server in each of the fault domains. The subnet also
provides object storage and a persistent volume.
- Database private subnet: Provides an instance of Oracle Autonomous JSON Database connected to the OKE cluster in the server subnet.
