Description of the illustration high-level-arch-single-availability-zone.png
This image depicts Autonomous Database on Dedicated Exadata Infrastructure’s high level architecture with a single availability zone.
The ODB Network is created like any VPC within AWS, but the provisioning workflow is started from Oracle Database @AWS service resource links. The ODB Network will specify a subnet hosting database service VM nodes (client subnet) and, optionally, a subnet for backup traffic, as well as an application VPC to be peered with the ODB Network. You should plan the size of your ODB Network appropriately based on the number of VM nodes you expect to host in your Exadata Infrastructures, as each of these resources will require an IP reservation. In general, in an ODB Network, the database client subnet will reserve 4 IPs for each VM in your clusters, plus an additional 8 IPs and the backup subnet (not required if only using the Autonomous Database service) will reserve 3 IPs for each VM in your clusters, plus an additional 3 IPs.
