65. Introduction to AWS Direct Connect

Amazon Web Services (AWS) Direct Connect is a network connection service that allows a private network to be extended directly into the AWS cloud. Through Direct Connect, users can establish a dedicated network connection between their data center, office or colocation environment and AWS. This provides a more consistent and predictable alternative to connecting over the Internet.

How does AWS Direct Connect work?

AWS Direct Connect is not an Internet-based service; instead, it uses a dedicated network connection that is established using a private line from a telecommunications service provider. This connection is then routed to an AWS Direct Connect Point of Presence (PoP), typically located in a colocation data center. From there, the connection is established directly with AWS.

This dedicated connection not only provides greater consistency and predictability of network performance, but can also offer cost benefits. For example, when transferring large amounts of data to AWS, users can avoid internet data transfer fees and pay Direct Connect data transfer fees instead, which are generally lower.

Configuring AWS Direct Connect

Setting up AWS Direct Connect involves several steps. First, the user must request a Direct Connect connection through the AWS Management Console. During this process, the user specifies the location of the Direct Connect PoP, the capacity of the connection and the telecommunications service provider that will provide the leased line.

Once the request is approved by AWS, the user must work with the telecom service provider to establish the private line. Once the private line is in place, the user can configure the Direct Connect connection, specifying the routing details and establishing a Virtual Private Gateway in AWS to connect the private network to AWS.

Benefits of AWS Direct Connect

There are many benefits to using AWS Direct Connect. First, it provides a dedicated network connection, which can result in more consistent and predictable network performance. This is particularly useful for applications that require high data transfer rates or low latency.

Second, Direct Connect can offer cost benefits. When transferring large volumes of data to AWS, users can avoid Internet data transfer fees and pay Direct Connect data transfer fees instead, which are generally lower.

Third, Direct Connect offers greater security. Since the connection is dedicated and does not go over the Internet, the data is less susceptible to eavesdropping or interruption attacks.

Conclusion

In short, AWS Direct Connect is a network connection service that allows users to extend a private network directly into AWS. It offers a more consistent and predictable alternative to connecting over the Internet, along with potential cost and security benefits. Setting up Direct Connect involves several steps, including requesting a connection, establishing a private line with a telecom service provider, and configuring the connection in the AWS Management Console.
