This image shows a multicloud environment with two cloud providers, OCI and AWS, that are connected by the Megaport backbone.

In the OCI cloud, there is a region that contains three availability domains. Within the region, there is an object storage bucket and a VCN. The VCN includes a dynamic routing gateway and contains a subnet that spans the availability domains. The subnet contains:
  • A standby Oracle Database in the first availability domain.
  • A backup observer for FSFO in the second availability domain.
  • A standby Oracle Database in the third availability domain.

The standby Oracle Database in the first availability domain backs up data to the object storage that is outside the VCN.

The AWS cloud mirrors the OCI cloud, with a few differences. In the AWS cloud, there is a region that contains three availability zones. Within the region, there is a Direct Connect gateway, an AWS Transit Gateway, an S3 bucket, and a VPC. The VPC contains a subnet that spans the availability zones. The subnet contains:

The standby Oracle Database in the third availability zone backs up data to the S3 bucket that is outside the VPC.

Between the two cloud regions is the Megaport backbone. This includes two Megaport cloud routers that work in parallel.

The OCI region connects to the Megaport backbone through the dynamic routing gateway, which uses Oracle FastConnect to connect to a Megaport VXC, which then connects to the Megaport Cloud Router. There are two parallel FastConnect connections, one for each Megaport Cloud Router.

The AWS region connects to the Megaport backbone through the AWS Transit gateway and then the Direct Connect gateway. The Direct Connect gateway uses AWS Direct Connect Transit VIF to connect to a Megaport VXC, which then connects to the Megaport Cloud router. There are two parallel AWS Direct Connect Transit VIFs, one for each Megaport Cloud Router.
