Description of the illustration architecture-hortonworks.png

The diagram illustrates the minimum architecture for deploying Hortonworks on Oracle Cloud Infrastructure.

The image shows an Oracle Region. Within the Region, an Availability Domain contains various components. A Hortonworks VCN encompasses an Internet / Service / NAT Gateway, and all of the components within the availabilty Domain.

Within the Availability Domain are a Bastion Subnet, a Public Subnet, and a Private Subnet. The Bastion Subnet contains one Edge VM component. The Public Subnet contains one Ambari VM component. The Private Subnet contains two Master components and three Worker components. Each of the subnets is protected by a firewall. The Edge VM component and the Ambari VM component are connected to the components in the Private Subnet through these firewalls.
