AWS Elastic Load Balancer helps to manage and control the flow of inbound requests destined to a group of targets by distributing these requests evenly across the targeted resource group. These targets could be a group of EC2 Instances, Containers, Lambda functions or a range of IP addresses.
Depending on the traffic distribution there are different types of ELBs available within AWS including Application Load Balancer, Network Load Balancer, Gateway Load Balancer, and Classic Load Balancer.
In this article we will focus on Network Load Balancer. Network Load Balancers are used for ultra high performance while at the same time maintaining very low latencies. It operates at the connection level, routing traffic to targets within your VPC. It is capable of handling millions of requests per second. The Network Load Balancer works at layer 4 of the OSI model, which is the Transport layer, enabling you to balance requests purely based on TCP and UDP protocols.
Following are the steps to create a Network Load Balancer on AWS:
Choose IPv4 if your clients use IPv4 addresses to communicate with the load balancer, or choose Dualstack if your clients use both IPv4 and IPv6 addresses to communicate with the load balancer.
This article is a quick walkthrough of how you can create a Network Load Balancer on AWS. It serves as a step by step guide for those who are looking to get started with AWS Network Load Balancers.
