Step-by-Step Guide: Creating a Direct Connect Connection

In this section, we will walk you through the process of creating a Direct Connect connection.

Log in to the AWS Management Console and navigate to the AWS Direct Connect dashboard.
Click on the "Direct Connect" tab and then click "Create a connection."
Select the Direct Connect location where you want to establish the connection.
Choose the connection type (dedicated or hosted) and the desired bandwidth.
Fill out the required information, such as the connection name, BGP ASN, and IP address range.
Review your order and submit it.
Once your order is approved, you will receive a Letter of Authorization (LOA) from AWS.
Use the LOA to establish the physical connection between your on-premises infrastructure and the Direct Connect location.
After the physical connection is established, create a virtual interface over the connection.
Test the connection and start using AWS services as you normally would.

Pricing Overview

AWS Direct Connect pricing is based on the following components:

Port hours: You are charged for the number of hours your dedicated or hosted connection is active, regardless of usage.
Data transfer: You are charged for data transferred over your Direct Connect connection, based on the region and the amount of data transferred.
Cross-region data transfer: You are charged for data transferred between regions, based on the source and destination regions and the amount of data transferred.

Here's an example to help you understand the pricing:

Suppose you have a 1 Gbps Direct Connect connection in the US East (Ohio) region.
You are charged $0.25 per port hour, resulting in a monthly cost of $180 (based on 720 hours per month).
If you transfer 1 TB of data over your Direct Connect connection, you are charged $0.10 per GB, resulting in a data transfer cost of $100.
If you transfer 100 GB of data between the US East (Ohio) and US West (Oregon) regions, you are charged $0.02 per GB, resulting in a cross-region data transfer cost of $2.

Keep in mind that these prices are just examples and may vary based on your specific needs and location.
