What Is Direct Connect Gateway In AWS?

AWS Direct Connect gateway is a private network service used to make the most of AWS cloud services. If you would like to bypass the public internet for making the data transfer more secure between your on-premises infrastructure and AWS then this is the solution for you.

It offers a cloud service to connect on-site servers with AWS cloud services. It also provides for a much better customer experience as it gives users the ability to have low latency and establish a more secure connection than the Internet.

In technical terms, a Direct Connect gateway is a set of virtual private gateways together with private virtual interfaces.

The best part about a Direct Connect gateway is that it provides access to any region once a Direct Connect gateway has been established. It is a resource available to customers all over the world.

Benefits of Using AWS Direct Connect Gateway?

The high pricing of AWS Direct Connect may put off some users from using the incredible and fast service. Using a private network to establish connections has many benefits for the user.

It has a better and increased bandwidth, consistent network connection (which is more important for working with large files on the Internet), and the ability to reduce costs.

Several AWS services can be used with AWS Direct Connect easily. Amazon DynamoDB, Amazon Elastic Compute Cloud (EC2), Amazon Simple Storage Service (S3), and Amazon Virtual Private Cloud are a few of them.

You can access the AWS cloud services to deal with your workload without fearing the breach of privacy. This also means that the entire process of working with AWS cloud services has been made faster with quicker access speed.

Is AWS Direct Connect Gateway Secure?

The most common concern with using a private network to connect your server is privacy. Customers want to know if their privacy or the security of their files will be threatened by third-party sources.

The answer to that is: No. The AWS Direct Connect may not include the Internet’s help to connect to AWS cloud services, but it uses a completely secure network to link your server’s Intranet with the Amazon VPC.

If customers are still not assured about the secure link, they can easily install security controls to encrypt the traffic for direct connections by using known protocols like HTTP, SSH, and SSL.

Do I Need AWS Direct Connect gateway?

AWS Direct Connect gateway offers a variety of services and benefits to its customers. It performs the following functions:

  • The Direct Connect gateway has the ability to give customers access to Virtual Private Clouds anywhere in the AWS region (AWS China not included). This helps clients in connecting to more than a single AWS Region.
  • Private Virtual Interfaces can be easily interfaced to several Virtual Private Clouds (up to 10). This reduces the number of Border Gateway Protocol sessions in your local servers and AWS networks.
  • Direct Connect gateway does support more than one Virtual Private gateway. This can only be possible if the CIDR blocks IP of the Amazon VPC do not coincide or overlap.

How are AWS Direct Connect gateway and VPN Different?

Another service similar to AWS Direct Connect is a VPN. If you want to know which service is the best (AWS Direct Connect Vs. VPN), keep on reading to find out which will suit your needs best.

A VPN or a virtual private network is a secured private network that is extended across a public network between your data center and AWS here. This in turn helps in protecting the data and of course it’s secure. A VPN hides your online identity by encrypting your internet traffic.

A VPN may sound closely similar to Direct Connect, but there is a significant difference between the two services.

  • A VPN connection will utilize IPsec to create and build an encrypted network over the Internet between your server and the Amazon Virtual Private Cloud. Whereas on the other hand, Direct Connect from AWS bypasses the Internet itself.
  • Direct Connect is used to connect your Intranet and the Amazon VPC bypassing the regular public internet. VPN connections can be easily and quickly formed and are perfect for an urgent need.
  • VPN offers a low-cost solution, but the performance of AWS is much more superior. AWS is not the most cost-effective option and can prove to be quite expensive but has unmatched stellar performance.
  • The bandwidth throughput of the Direct Connect is greater with little to no fluctuation in the network connection and data transfer.
  • Due to the VPNs connection with private as well as public networks, there may be fluctuations in the network, and data transfer may not be as smooth.

What Are AWS Direct Connect gateway Locations?

AWS Direct Connect can be accessed from several locations around the globe. AWS Direct Connect is accessible in a few campuses using cross-connects from data centers managed by the same operator with the exact campus.

It is recommended for AWS Direct Connect users to opt for more than one location for high availability. All AWS Regions can be accessed from multiple AWS Direct Connect access points in the world (China as the exception).

When a user utilizes the Public Virtual Interfaces or AWS Direct Connect gateways, the traffic from the user goes to the destined AWS region from the chosen AWS Direct Connect location without bypassing the linked AWS region.

It is advisable to select the closest AWS Direct Connect location from your on-site server in order to reduce costs. This way will also help you attain the lowest latency. The AWS Direct Connect regions are.

What Is AWS Direct Connect Pricing?

AWS Direct Connect offers a fast, low latency, and consistent service to connect your server directly to AWS cloud services. The best part about using AWS Direct Connect is that there is no monthly pay or subscription, but you only pay for the services and time you use.

There are three factors used by AWS to determine the pricing of AWS Direct Connect: data transfer-out, port-hours, and capacity.

  • Capacity refers to the highest limit rate of data (Megabits per second or Gigabits per second) that can be transferred through the connection.
  • Port hours is the amount of time allotted to use the AWS or the AWS Direct Connect Delivery Partner’s network tools within an AWS Direct Connect location.
  • It is further divided into two types per the kind of connection used: Dedicated port-hours and Hosted port-hours. Even though you are not using your port to send out data or receive it, you will still be charged for the port hours.
  • The data transfer out term related to total traffic sent over the AWS Direct Connect to locations that are not a part of the AWS. The pricing for data transfer out is according to the gigabytes of transmitted data (unlike capacity measurements which deal with speed).
