This image shows a scalable, high-performance data storage and data movement platform designed for optimum data access latency and bandwidth, especially during workload spikes.

The architecture uses a single region with 1 availability domain with 3 fault domains. A single virtual cloud network (VCN) includes the following gateways:

• Internet gateway: Provides communications between public subnets and internet hosts.
• Network address translation (NAT) gateway: Enables private resources in a VCN to access hosts on the internet, without exposing those resources to incoming internet connections.
• Dynamic routing gateway (DRG): Provides private connectivity between on-premises networks and VCNs by using Site-to-Site VPN or FastConnect.

The VCN provides GlusterFS block storage distributed across the fault domains and two public subnets with security lists and route tables:

• Bastion public subnet: Provides a Bastion head node to handle incoming traffic
• File system public subnet: Provides GlusterFS on Bare Metal servers with Linux KVM and RAMFS distributed across fault domains
