The image shows GoToro's Oracle Cloud Infrastructure (OCI) and third-party cloud environment.

Internet users, such as administrators, developers, candidates, managed clients, and self-managed clients, access the OCI region by using an internet gateway. Similarly, third-party cloud and data integration users, such as business intelligence (BI) dashboards, social authentication providers, applicant tracking systems (ATS) such as Oracle Recruiting Cloud Service, SMS and email providers, and job publishers also access the OCI region by using an internet gateway.

The OCI region provides 2 availability domains and a single virtual cloud network (VCN) with 3 subnets. The region provides the following services:

Oracle Cloud Infrastructure Alarms
Oracle Cloud Infrastructure Bastion
Oracle Cloud Infrastructure DevOps
Oracle Cloud Infrastructure Domain Name Service (DNS)
Oracle Cloud Infrastructure Identity and Access Management
Oracle Cloud Infrastructure Monitoring
Oracle Cloud Infrastructure Notifications
Oracle Cloud Infrastructure Object Storage
Oracle Cloud Infrastructure Streaming
Oracle Cloud Infrastructure Registry

The VCN provides the following gateways:

Internet gateway: Provides communications between public subnets and internet hosts.
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 a load balancer in availability domain 2 to handle incoming request traffic.
OKE private subnet: Provides an Oracle Cloud Infrastructure Container Engine for Kubernetes cluster that provides services, such as scheduled tasks, back-end and front-end services, search, data analytics, messaging, DBMS, chat, and tracking services. The subnet also provides QA and automation in availability domain 2.
Database private subnet: Provides a primary Oracle MySQL Database Service in availability domain 1 which is replicated to a standby instance in availability domain 2.
