Oracle database migration: Cross-cloud connectivity

Azure ExpressRoute
Azure Virtual Machines
Azure Virtual Network
Azure VPN Gateway

To support a multicloud experience, you can create a direct interconnection between Azure and Oracle Cloud Infrastructure (OCI) by using Azure ExpressRoute and FastConnect. The connection between the services allows applications hosted on Azure to communicate with Oracle database hosted on OCI. You can expect low latency and high throughput by connecting an ExpressRoute circuit in Azure with a FastConnect circuit in OCI.

  1. Establish a connection between Azure ExpressRoute and OCI FastConnect.

  2. Your Azure application can communicate with your OCI-hosted Oracle database.
