Dedicated Connectivity Comparison

Private Connectivity Options

Provider	Service	Typical Use

Azure	ExpressRoute	Dedicated enterprise connectivity into VNets and Microsoft services
GCP	Cloud Interconnect	Dedicated or partner connectivity into VPCs
OCI	FastConnect	Private connectivity into VCNs through DRG attachments

Design Guidance

1. Prefer redundant circuits in separate facilities for production workloads.
2. Terminate private links into central transit or hub networking layers.
3. Use VPN as backup even when dedicated links are primary.
4. Validate BGP advertisements, failover behavior, and MTU assumptions during testing.
