Direct Connect
Definition
AWS service that creates a dedicated, private network connection from your office or data center directly to AWS for improved performance and security.
Use Cases
- Netflix: High-throughput, reliable connectivity between Netflix’s production environment and AWS regions for large-scale streaming operations. — Netflix has publicly discussed using AWS Direct Connect as part of its network connectivity to AWS, typically via colocation/partner facilities with redundant connections and BGP routing for resilience. (More predictable network performance and improved reliability versus internet-based connectivity for critical data transfers and operational traffic.)
- FINRA: Secure, high-bandwidth transfer of regulatory and market-related datasets into AWS for analytics and processing. — FINRA has publicly referenced using AWS services for cloud initiatives; a common pattern for regulated institutions is to use AWS Direct Connect with redundant links, private virtual interfaces, and BGP to connect data centers to AWS VPCs. (Improved data transfer reliability and better control over network paths compared to public internet connectivity, supporting compliance-focused operations.)
- The Walt Disney Company: Hybrid connectivity for moving large media and operational datasets between on-premises environments and AWS for processing and storage. — Disney has publicly discussed AWS usage; a typical enterprise media implementation uses AWS Direct Connect through a colocation provider, with multiple circuits for high availability and segmentation using separate virtual interfaces. (Faster, more consistent transfers for large files and reduced operational risk from internet variability.)

Frequently Asked Questions
- What's the difference between AWS Direct Connect and a Site-to-Site VPN?
- Direct Connect is a private network connection that uses dedicated or partner-provisioned circuits to reach AWS without traversing the public internet. A Site-to-Site VPN encrypts traffic over the public internet. VPNs are usually quicker to set up and cheaper to start, but performance can vary with internet conditions. Direct Connect typically offers more consistent bandwidth and latency, and is often used for steady, high-volume, or latency-sensitive traffic.
- When should I use AWS Direct Connect?
- Use Direct Connect when you need predictable network performance, regularly move large amounts of data to/from AWS, have latency-sensitive applications, or must keep traffic off the public internet for policy or risk reasons. It’s also common in hybrid architectures where on-premises systems must reliably communicate with AWS VPCs. Many organizations start with VPN and add Direct Connect as usage grows or requirements tighten.
- How much does AWS Direct Connect cost?
- Costs typically include: (1) AWS Direct Connect port-hour charges (based on port speed and hours provisioned), (2) data transfer out from AWS over Direct Connect (often priced differently than internet egress), and (3) third-party costs such as colocation cross-connects, last-mile circuits, or Direct Connect Partner fees. Pricing varies by region, port speed, and connectivity model (dedicated port vs partner-hosted). For accurate numbers, use the AWS Direct Connect pricing page and include provider/colocation quotes in your estimate.
