Network planning for Oracle Database@Azure

  • Article

In this article, you learn about the topologies and constraints for Oracle Database@Azure. After you purchase the offer through Azure Marketplace and provision the Exadata infrastructure, you'll then need to create your virtual machine cluster that will host your Oracle Exadata Database. These Oracle database clusters are connected to your Azure virtual network via a virtual NIC from your delegated subnet (delegated to Oracle.Database/networkAttachement).

Supported topologies

The following table describes the network topologies supported by each network features configuration of Oracle Database@Azure.

Topology Supported
Connectivity to Oracle database cluster in a local virtual network Yes
Connectivity to Oracle database cluster in a peered virtual network (Same region) Yes
Connectivity to Oracle database cluster in a spoke VNet in a different region with VWAN Yes
Connectivity to Oracle database cluster in a peered virtual network* (Cross region or global peering)* without VWAN No
On-premises connectivity to Oracle database cluster via Global and Local Expressroute Yes
ExpressRoute (ER) FastPath No
Connectivity from on-premises to Oracle database cluster in a spoke virtual network over ExpressRoute gateway and virtual network peering with gateway transit Yes
On-premises connectivity to Delegated Subnet via VPN GW Yes
Connectivity from on-premises to Oracle database in a spoke virtual network over VPN gateway and virtual network peering with gateway transit Yes
Connectivity over Active/Passive VPN gateways Yes
Connectivity over Active/Active VPN gateways No
Connectivity over Active/Active Zone Redundant gateways No
Transit connectivity via vWAN for Oracle database cluster provisioned in spoke virtual networks Yes
On-premises connectivity to Oracle database cluster via vWAN attached SD-WAN No
On-premises connectivity via Secured HUB (Firewall NVA) No
Connectivity from Oracle database cluster on Oracle Database@Azure nodes to Azure resources Yes
  • You can overcome this limitation by setting Site-to-Site VPN.

Constraints

The following table describes the configuration of supported network features:

Features Basic network features
Delegated subnet per virtual network 1
Network Security Groups on Oracle Database@Azure-delegated subnets No
User-defined routes (UDRs) on Oracle Database@Azure-delegated subnets Yes
Connectivity from Oracle database cluster to private endpoints in the same virtual network on Azure-delegated subnets No
Connectivity from Oracle database cluster to private endpoints in a different spoke virtual network connected to vWAN Yes
Load balancers for Oracle database cluster traffic No
Dual stack (IPv4 and IPv6) virtual network IPv4 only supported.
