The image shows a customer GridServer client on-premises using a site-to-site VPN to connect to a dynamic routing gateway within an Oracle Cloud Infrastructure (OCI) region.

The OCI region is comprised of a virtual cloud network (VCN), one availability domain, and three subnets.

• Subnet A (GridServer Management): The CIDR of this subnet is 10.0.30.0/24. This subnet contains a Bastion, GridServer Manager, GridServer Clients, and GridServer Brokers.
• Subnet B (GridServer Engines): The CIDR of this subnet is 10.0.32.0/24. This subnet contains GridServer Engines.
• Subnet C (Storage): The CIDR of this subnet is 10.0.33.0/24. This subnet contains persistent block storage.

Outside of the VCN are other OCI services such as Oracle Cloud Infrastructure Search, Oracle Cloud Infrastructure Identity and Access Management, and Oracle Cloud Infrastructure Object Storage.
