Amazon Virtual Private Cloud or Amazon VPC is a service that enables customers to create their virtual network in a secure and Isolated environment. VPC offers us a secure environment in which we can create our network and use Amazon services as needed. You can have full control over VPC. whether its creation, customization or deletion. The user can control it easily.

It’s effective for companies with a lot of data that has to be managed effectively. To put it another way, VPC allows us to choose the virtual address of our private cloud and to define all of the VPC’s sub-constituents on our own, such as subnet, subnet mask, availability zone, and so on.

When it comes to the technical description of VPC. It can be defined in an AWS region. And, as is well known, multiple availability zones exist within the region. It should be mentioned that VPC can be distributed throughout all availability zones within a region.  

In this article, we’ll discuss the relevance of Amazon VPC and how it interacts with direct connect services.

The Structure of Amazon VPC:

Amazon VPC enables the installation of AWS resources into a defined virtual network. This virtual network closely resembles a regular network in your own data center, but with the added benefit of AWS’ scalable infrastructure. Concepts for Amazon VPC.

Amazon VPC is made up of various networking components. Here is the list of a few key components of Amazon VPC:

  1. Subnets
  2. Elastic network interfaces
  3. Route tables
  4. Internet gateways
  5. Elastic IP addresses
  6. VPC endpoints
  7. NAT
  8. VPC peering

Many different services, such as Gateway, Load Balancer, Subnets, and so on, make up the core architecture of a well-operating VPC. To build an isolated virtual environment, these resources are grouped under a VPC. Along with these services, there are numerous degrees of security checks.

It is first separated into subnets, which are linked together via route tables and a load balancer. The entire configuration is protected by an internet gateway.

To understand the structure better, here is a diagram below:

Working with Direct Connect Services:

AWS direct connect facilitates the installation of dedicated network connections from your premises to your Amazon VPC or between Amazon VPCs. It provides users with an efficient method of connecting. Its use can efficiently cut network costs. It can give a more consistent network experience and boost bandwidth throughput than other VPC-to-VPC connecting methods. Because traffic can take advantage of 1 Gbps or 10 Gbps fiber links physically connecting to the AWS network in each area, AWS Direct Connect can enable exceptionally efficient routing.

Furthermore, this solution provides the most control and management options for routing on your local and remote networks, as well as the capability to reuse AWS Direct Connect connections.

A physical AWS Direct Connect connection can be divided into many logical connections, one for each VPC. As shown in the diagram below, you can then use these logical connections to route traffic between VPCs. In addition to intra-region routing, you can use your current WAN providers to connect AWS Direct Connect locations in other regions and use AWS Direct Connect to route traffic across regions through your WAN backbone network.

Benefits of using Direct Connect:

Following are the benefits of using AWS Direct Connect:

  1. Lower Bandwidth Costs:  First, any data transferred over your dedicated connection is charged at the lower AWS Direct Connect data transfer rate rather than the higher Internet data transfer rate. Also, by sending data directly to and from AWS, you can minimize your bandwidth commitment to your Internet service provider.
  2. Private Linkage to AWS VPC: Using Direct Connect Private Virtual Interface, you can establish a private, dedicated, high-speed network link between your network and VPC.
  3. Consistent Flow Of network traffic: When compared to the Internet, Direct Connect gives a dedicated connection and a more consistent network performance experience.
  4. Amazon Web services Compatibility: Direct Connect is a network service that is compatible with all AWS services such as S3, EC2, and VPC.
  5. Elastic: Direct Connect may be easily scaled to suit the needs of the user by employing a higher bandwidth connection or establishing numerous connections.

Finally, Amazon VPC allows users to create a virtual network in the AWS cloud where you may establish and govern your own network space. Working with Amazon direct connect services is a quick and easy way to connect. It can help you save money. And there are other advantages to adopting Amazon direct connect services.
