The image shows an OCI region with two Availability Domains (ADs), Availability Domain 1 and Availability Domain two. A VCN with an Oracle Cloud Infrastructure File Storage (FSS) Subnet and a Mid-tier Subnet span both ADs.

Within the FSS Subnet in AD1 is Mount Target AD1, which is connected to the following in the FSS Subnet: Products1 File System grouped with a Private Config File System, Shared Config File System, and Shared runtime File System.

Within the FSS Subnet in AD2 is Mount Target AD2, which is connected to Products2 File System grouped with a Private Config File System.

The Private Config File Systems in each AD can instead be Oracle Cloud Infrastructure Block Volumes.

Within the Mid-tier Subnet in AD1 is AppHost1 and in AD2 is AppHost2.

Information flows from AppHost1 to Products1 File System and the Private Config File System, Shared Config File System, and Shared runtime File System in AD1.

Information flows from AppHost 2 to Products2 File System and the Private Config File System in AD2 and to the Shared Config File System, and Shared runtime File System in AD1.
