Step-By-Step Process to create AWS Network Load Balancer
Step 1: Create Load Balancer
- Now Go to AWS Management console and search for AWS Load Balancer and choose create load balancer.
- It’s shows Load balancer types like Application Load Balancer, Network Load Balancer and Gateway Load Balancer.
- We need to create a network load balancer, so choose on Network Load Balancer.
Step 2: Create Network Load Balancer
- The Network Load Balancer distributes incoming TCP and UDP traffic across multiple targets such as Amazon EC2 instances, microservices, and containers. When the load balancer receives a connection request, it selects a target based on the protocol and port that are specified in the listener configuration, and the routing rule specified as the default action.
- Now give name to Load balancer, Name must be unique within your AWS account and can’t be changed after the load balancer is created.
Step 3: Network Mapping
- The load balancer routes traffic to targets in the selected subnets, and in accordance with your IP address settings.
- Mappings: Select at least one Availability Zone and one subnet for each zone. We recommend selecting at least two Availability Zones. The load balancer will route traffic only to targets in the selected Availability Zones. Zones that are not supported by the load balancer or VPC can’t be selected. Subnets can be added, but not removed, once a load balancer is created.
Step 4: Security Groups
- A security group is a set of firewall rules that control the traffic to your load balancer. Select an existing security group, or you can create a new security group.
Step 5: Creating Target Groups
- Our load balancer routes requests to the targets in a target group and performs health checks on the targets. So we need to create a target groups
- Now specify target group details i.e choose instance or IP address e.t.c and specify target group name
- Choose protocol port like http, httpd, tcp or any traffic.
Health checks
- The associated load balancer periodically sends requests, per the settings below, to the registered targets to test their status.
- Now click on next and choose create target group.
Step 6: Listeners And Routing
- A listener is a process that checks for connection requests using the port and protocol you configure. The rules that you define for a listener determine how the load balancer routes requests to its registered targets.
- Select created target group its shown in drop down menu.
- Now review and click on create load balancer.
- Here in below figures we can see that created load balancer.
Steps to Delete the Network Load Balancer
Step 1: Navigate to the EC2 Dashboard.
Step 2: Under “Load Balancing,” select “Load Balancers”. Choose NLB you want to delete from the list of load balancers.
Step 3: Click the “Actions” dropdown.
Step 4: Choose “Delete” from the dropdown menu.
