FastConnect supports 1 Gbps, 10 Gbps, and 100 Gbps circuits through Oracle partners, colocation providers, or direct cross-connects at Oracle data centers. This builder helps you configure FastConnect virtual circuits with BGP settings, bandwidth shapes, cross-connect groups, and redundancy configurations for production-grade hybrid connectivity.
FastConnect offers three connectivity models: Colocation with Oracle means your equipment is in the same data center as Oracle (direct cross-connect). Partner network uses a third-party network provider (like Equinix, Megaport, or AT&T) to connect your data center to Oracle. Third-party provider offers pre-established connectivity through select providers. Each model supports both private peering (access VCN resources) and public peering (access Oracle public services over the private link).
Oracle recommends provisioning at least two FastConnect virtual circuits, ideally through different providers or in different physical locations. Each virtual circuit establishes an independent BGP session with your on-premises router. If one circuit fails, BGP automatically reroutes traffic to the remaining circuit. For maximum resilience, combine FastConnect with IPSec VPN as a backup path that activates if both FastConnect circuits are unavailable.
Your team is connecting an on-prem datacenter to OCI for a 5 Gbps hybrid workload with $20K/month of expected egress to OCI Object Storage. The builder generates: 2 FastConnect virtual circuits at 5 Gbps each through Equinix Ashburn (different cabinets for redundancy), private peering for VCN access, public peering for Object Storage. Total monthly cost: ~$2,400 for the circuits. Equivalent on AWS Direct Connect: $1,800 circuits + $20,000/month data transfer = $21,800. OCI saves ~$19K/month on the same hybrid workload purely because data transfer is free on FastConnect.
The builder constructs OCI FastConnect virtual circuit configurations: virtual circuit resource (type: PRIVATE or PUBLIC, bandwidth shape: 1/2/5/10 Gbps, provider name, customer ASN, BGP MD5 auth key, customer/Oracle BGP peer IPs in the /30 link subnet, Oracle BGP ASN), cross-connect or cross-connect group reference, and DRG attachment for private circuits. Output is generated as oci network virtual-circuit commands and Terraform oci_core_virtual_circuit resources.
OCI FastConnect's lack of data transfer charges is the #1 reason organizations consider OCI for hybrid workloads. AWS Direct Connect at $0.02/GB on a 5 Gbps sustained link adds $50K+/year in egress alone — OCI FastConnect at the same bandwidth has $0 in data charges. For high-throughput hybrid, the savings are enormous.
Always order TWO FastConnect circuits, ideally through different providers or different physical locations. The marginal cost of the second circuit is much less than a single multi-hour outage. Oracle's SLA requires redundant circuits anyway.
Public peering on FastConnect lets you reach OCI public services (Object Storage, OCI APIs) over the dedicated link without going through the internet. For high-throughput data transfer to/from Object Storage, this is dramatically faster AND keeps traffic off the public internet — security AND performance win.
