You can use Oracle Cloud Infrastructure FastConnect Classic to access Oracle Database Exadata Cloud Service using a reliable, private and direct connection from your corporate network. When you use FastConnect Classic, your network traffic is routed over a direct and deterministic path that is separate from the public Internet. Consequently, FastConnect Classic provides guaranteed bandwidth and delivers consistent performance and latency.
FastConnect Classic is an add-on networking service, which is available for an additional subscription fee. FastConnect Classic is offered in increments of 1 Gbps and 10 Gbps, and you can combine 1 Gbps and 10 Gbps ports to meet your required network bandwidth.
The configuration of FastConnect Classic depends on the network configuration of the Exadata Cloud Service instance:
If the Exadata Cloud Service instance is configured to use IP networks, FastConnect private peering is used. In this case, your corporate network RFC1918 IP address space is advertised to the Oracle FastConnect router and Oracle advertises the RFC1918 IP address spaces of the IP networks.
If the Exadata Cloud Service instance is not configured to use IP networks, FastConnect public peering is used. In this case, your corporate network public IP addresses are advertised to the Oracle FastConnect router. If your corporate network used private IP addresses internally, then you must use a Network Address Translation (NAT) to define the required public addresses. Oracle advertises all of the public IP addresses assigned to your Exadata Cloud Service instance.
The FastConnect provisioning process is a collaborative effort between Oracle Cloud network engineers and your corporate network administrators, which starts when you make a service request to configure FastConnect Classic in conjunction with Exadata Cloud Service.
