This image shows a multicloud environment with two cloud providers, OCI and AWS, that are connected by the Colt backbone.
- 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:
- A primary Oracle Database in the first availability zone.
- A master observer for FSFO in the second availability zone.
- A standby Oracle Database in the third availability zone.
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 Colt backbone. This includes four Colt IP Gateways and four Colt Circuit On-ramps.
The OCI region connects to the Colt backbone through the dynamic routing gateway, which uses Oracle FastConnect and a Partner Interconnect (L3/Ethernet + BGP) to connect to a Colt Circuit On-ramp. The on-ramp connects to a Colt IP Gateway, which then connects to the Colt Global Backbone. There are two parallel connections from OCI to Colt, and both use that structure.
The AWS region connects to the Colt backbone through the AWS Transit gateway and then the Direct Connect gateway. The Direct Connect gateway uses AWS Direct Connect Transit VIF and a Partner Interconnect (L3/Ethernet + BGP) to connect to a Colt Circuit On-ramp. The on-ramp connects to a Colt IP Gateway, which then connects to the Colt Global Backbone. There are two parallel connections from AWS to Colt, and both use that structure.
