Step-By-Step Process to Configure GateWay Load Balancer in AWS

How Gateway Load Balancers work

Conclusion

Step 1: Create a Gateway Load Balancer

Now go to AWS Console and login with your credentials are create a new account.
Now go to AWS Management console and Navigate to Load Balancing section
There is an option Load balancers and click on create load balancer

Now it’s shows three options like Application Load Balancer, Network load balancer and Gateway load balancer
Choose Gateway load Balancer from the left-hand menu and choose “Create Load Balancer.”

In Basic configuration section Give name to load balancer that helps easy to identify and select IP Address as IPv4

Network Mapping

Select VPC and Subnet. The load balancer routes traffic to targets in the selected subnets, and in accordance with your IP address settings
Select the virtual private cloud (VPC) for your targets or you can create a new VPC . The selected VPC can’t be changed after the load balancer is created. To confirm the VPC for your targets, view your target groups

Now before going to IP listener group create target group or else choose if you have an existing target group
Now go to target groups and choose create target groups.

Now choose new target group and specify the target type (e.g., instance or IP).

Now Define health checks to monitor the health of targets.

Step 2: Register Targets

In this step we are registering target groups
Once target groups are created, register the desired targets (e.g., EC2 instances) with the target group.

Now select available instances and click on create target group

Here we see that successfully created target group

Now we are moving to previous section that is step-1
Here we select our loadbalancer

Here we see that our loadbalancer was successfully created and also see details of our load balancer

Listeners and rules was attached to load balancer successfully

Step 3: Set Up Routing

Configure routing tables in your VPC to direct traffic to the Gateway Load Balancer. Here we see that below figure

Update the route tables associated with your subnets to route traffic destined for the internet gateway to the Gateway Load Balancer. Here we see that below figure

How To Configure GateWay Load Balancer In AWS ?

In the advanced landscape of cloud computing, managing incoming internet traffic efficiently is fundamental for ensuring the accessibility, scalability, and reliability of applications. AWS offers a set of services to address these necessities, and one such help is the Gateway Load Balancer (GWLB).

Gateway Load Balancer is an incredible tool intended to distribute incoming traffic across multiple targets inside an Amazon Virtual Private Cloud (VPC). Dissimilar to other load balancers like Application Load Balancer (ALB) or Network Load Balancer (NLB), which work at higher layers of the OSI model, Gateway Load Balancer has capabilities at the network (Layer 3) level.

Understanding how to configure and use the Gateway Load Balancer is significant for architects and administrators managing AWS infrastructure. In this guide, we will delve into the primary terminologies related to GWLB, provide a step-by-step process for design, offer models and clarifications for better perception, and address habitually posed inquiries to ensure complete comprehension of this fundamental AWS administration. We should investigate how Gateway Load Balancer can improve the presentation, scalability, and reliability of your applications hosted on AWS.
