A direct interconnection refers to a dedicated, private connection between two systems or networks, bypassing the public internet. This type of connection is often established to enhance performance, reliability, and security.

Here are some key aspects and benefits of direct interconnections:

  1. Enhanced Performance: By bypassing the public internet and its potential bottlenecks and congestion, direct interconnections often provide lower latency and more consistent throughput.
  2. Improved Security: Direct interconnections can offer a more secure communication channel compared to transmitting data over the public internet. This is because the data doesn't traverse the myriad of networks that make up the internet, reducing the exposure to potential threats.
  3. Consistent and Predictable Network Behavior: By establishing a dedicated connection, organizations can expect consistent network performance, which is particularly crucial for applications requiring real-time data transfer or synchronization.
  4. Cost Efficiency: In some cases, especially for large volumes of data transfer, direct interconnections can be more cost-effective than transferring data over the public internet, due to reduced bandwidth costs or data transfer fees.
  5. Compliance and Data Sovereignty: For organizations subject to specific regulatory requirements, direct interconnections can help ensure that data flows are more controlled and restricted to specific paths or geographies.

Direct interconnections are especially prevalent in scenarios such as:

  • Data Center to Data Center: Organizations with multiple data centers may establish direct connections between them to facilitate efficient data synchronization and backup operations.
  • Enterprise to Cloud: Many enterprises establish direct connections to cloud service providers for better performance and security. Major cloud providers like AWS (with Direct Connect), Microsoft Azure (with ExpressRoute), and Google Cloud (with Cloud Interconnect) offer services that allow businesses to establish these direct connections from their infrastructure to the cloud.
  • Peering at Internet Exchanges: Companies might directly interconnect their networks at internet exchange points (IXPs) to exchange traffic directly, bypassing traditional internet transit routes.

In summary, a direct interconnection is a private, dedicated connection between two systems or networks, offering benefits in performance, security, and cost compared to transmitting data over the public internet.
