- Egress Toll Arbitrage: Standard AWS public internet egress costs $0.09 per GB (dropping to $0.05/GB at scale). Routing data out through AWS Direct Connect slashes egress rates down to $0.02 per GB—a 78% immediate discount that pays for dedicated port fees on high-volume pipelines.
- Dedicated Port vs. Software-Defined Network (SDN): Dedicated AWS Direct Connect requires physical cross-connects in an AWS-approved Meet-Me Room (MMR) with rigid 12-to-36 month telco commitments. Megaport establishes a single physical Port into their fabric, allowing engineers to spin up virtual cross-connects (VXCs) to AWS, Azure, GCP, and bare-metal colos via API in minutes.
- The BGP & Transit Gateway Toll: Terminating Direct Connect into an AWS Transit Gateway (TGW) incurs an extra $0.02/GB processing fee on top of Direct Connect port fees, frequently wiping out half of the anticipated egress savings unless Direct Connect Gateway (DX-GW) Private VIFs are utilized directly.

For enterprise infrastructure teams managing multi-petabyte datasets, public internet data transfer out of AWS represents a punishing operational tax. At 500 terabytes per month, standard internet egress costs approximately $41,000 every 30 days. Mitigating this expense requires establishing dedicated, private Layer 2 or Layer 3 transport directly into AWS VPC infrastructure.
Historically, this required leasing dedicated fiber optic cross-connects through telco carriers directly to an AWS Direct Connect (DX) location. In 2026, Network-as-a-Service (NaaS) providers like Megaport and Equinix Fabric have fundamentally altered hybrid cloud economics by virtualizing interconnection pipelines.
AWS Direct Connect vs. Megaport: What Is the Difference?
AWS Direct Connect provides dedicated physical fiber links between on-prem data centers and AWS with discounted $0.02/GB egress, but requires physical presence in an AWS partner facility. Megaport is a software-defined fabric that allows you to connect on-prem colos to AWS, Azure, and GCP simultaneously via API with flexible monthly billing.
Understanding the total cost of ownership requires modeling port fees, cross-connect charges, and transit gateway processing taxes.
Cloud Interconnect Architecture & Cost Breakdown
The following engineering table compares dedicated physical Direct Connect against Megaport Software-Defined Cloud Interconnect:
| Architectural Dimension | Native AWS Direct Connect (Dedicated) | Megaport Cloud Router (MCR / VXC) |
|---|---|---|
| Port Speed Options | 1 Gbps, 10 Gbps, 100 Gbps dedicated | 100 Mbps to 100 Gbps (dynamically burstable) |
| Provisioning Timeline | 3 to 8 weeks (LOA-CFA physical cross-connect) | < 10 minutes via Terraform / Web API |
| Data Egress Rate | $0.020 / GB (US East) | $0.020 / GB (AWS DX rate) + VXC transit |
| Fixed Monthly Port Cost | $0.30/hr ($216/mo) for 1G | $2.25/hr ($1,620/mo) for 10G | Pay-as-you-go hourly port + VXC bandwidth fee |
| Multi-Cloud Routing | AWS VPCs only (isolated) | Direct inter-cloud routing (AWS ➔ GCP / Azure) |
| BGP Routing Layer | Requires physical on-prem border router | Virtual BGP peering handled by Megaport MCR |
The Transit Gateway Processing Trap
The most common architectural pitfall in Direct Connect deployments is routing all traffic through an AWS Transit Gateway. While TGW simplifies network topology by aggregating hundreds of VPCs into a single routing hub, AWS charges an insidious $0.02 per gigabyte for all data traversing the Transit Gateway.
When combined with the Direct Connect egress rate of $0.02/GB, your total cost doubles to $0.04/GB. To maximize savings, high-bandwidth services (such as analytics pipelines or database replication streams) should bypass the Transit Gateway entirely by using Private Virtual Interfaces (Private VIFs) connected directly to dedicated Direct Connect Gateways associated with specific VPCs.
Multi-Cloud Egress Arbitrage via Megaport
Megaport’s decisive architectural advantage is the Megaport Cloud Router (MCR)—a managed virtual routing instance that lives inside global colocation facilities. Using MCR, enterprises can route traffic directly between AWS us-east-1 and Google Cloud us-central1 without backhauling packets across an on-premises physical data center.
This allows FinOps teams to exploit multi-cloud pricing disparities, siphoning heavy analytical workloads to cheaper GPU bare-metal providers while retaining core microservices inside AWS.
If your organization operates single-cloud infrastructure with steady monthly egress exceeding 100TB and already maintains racks inside an Equinix or CoreSite facility, commission a dedicated 10G AWS Direct Connect with Private VIFs for the absolute lowest $/GB unit cost. If you operate a multi-cloud or hybrid architecture requiring agile, API-driven connectivity to multiple providers without rigid telecom contracts, deploy Megaport Cloud Router to dynamically route packets at line rate.
