Understanding AWS Direct Connect
What is AWS Direct Connect?
AWS Direct Connect is a network service provided by Amazon Web Services that allows businesses to establish a dedicated network connection between their on-premises data center and AWS cloud infrastructure. It bypasses the public internet, providing a more reliable, secure, and high-performance connection.
How does AWS Direct Connect work?
AWS Direct Connect works by creating a private network connection between the customer’s data center and an AWS Direct Connect location. This connection is established using a dedicated network link provided by AWS partners. The data transfer between the customer’s data center and AWS cloud services can then be done over this dedicated network connection.
Benefits of using AWS Direct Connect
Using AWS Direct Connect offers several benefits for businesses. Firstly, it provides a more reliable and consistent network connection compared to relying on the public internet. This is particularly important for applications that require low latency and high network performance. Secondly, AWS Direct Connect improves security by bypassing the public internet and allowing for private connectivity. It also helps businesses save on data transfer costs as data transferred over the direct connection is charged at a lower rate compared to standard internet data transfer fees.
Preparing for AWS Direct Connect
Assessing your network requirements
Before setting up AWS Direct Connect, it is crucial to assess your network requirements. This involves evaluating the bandwidth needs, latency requirements, and traffic patterns of your applications and workloads.

Selecting the right AWS Direct Connect location is essential for optimizing network performance. AWS Direct Connect has multiple locations worldwide, and choosing a location that is geographically close to your data center will help minimize latency and improve network performance. Additionally, considering factors such as network service provider options and availability of AWS services at the chosen location is crucial.
Understanding the connectivity options
AWS Direct Connect offers different connectivity options, including dedicated connections and hosted connections. Dedicated connections provide a private, direct link between the customer’s data center and AWS. Hosted connections, on the other hand, allow customers to connect to AWS Direct Connect through a partner’s network. Understanding the pros and cons of each option will help in making the right connectivity choice for your organization.
Preparing your data center for AWS Direct Connect
Preparing your data center involves ensuring that the necessary networking equipment is in place to establish the connection with AWS Direct Connect. This includes having compatible routers, switches, and network cables. You will also need to work with your network service provider to configure the necessary circuits and obtain the required port capacity at the chosen AWS Direct Connect location.
Setting up AWS Direct Connect
Creating a Direct Connect Gateway
To set up AWS Direct Connect, you start by creating a Direct Connect Gateway. A Direct Connect Gateway simplifies the network configuration by allowing you to connect multiple virtual private clouds (VPCs) and virtual interfaces (VIFs) to a single Direct Connect connection. This centralizes the management of your connections and makes it easier to scale your network infrastructure.
Configuring Virtual Interfaces
After creating a Direct Connect Gateway, you can configure virtual interfaces to establish the connection between your on-premises data center and AWS. Virtual interfaces represent the logical connections between your data center and one or more VPCs in the AWS cloud. You can configure different types of virtual interfaces depending on your specific requirements, such as private VIFs for connecting to a VPC or public VIFs for accessing public AWS services.
Connecting to the AWS Direct Connect location
Once the Direct Connect Gateway and virtual interfaces are configured, you can establish the physical connection between your data center and the AWS Direct Connect location. This typically involves working with your network service provider to provision the necessary network circuits and connect them to your data center environment. Once the physical connection is established, you can start transmitting data between your data center and AWS.
Verifying the connection status
After setting up the AWS Direct Connect connection, it is crucial to verify the connection status to ensure that the link is active and functioning correctly. AWS provides monitoring and visibility tools that allow you to check the connection status and track network performance metrics. Verifying the connection status helps identify any potential issues early on and allows for prompt troubleshooting if required.
