Application Load Balancer vs Network Load Balancer vs Classic Load Balancer | AWS CSAA | Whizlabs

The most common types of alternatives among load balancers supported by Elastic Load Balancing include Application Load Balancer, Network Load Balancer and Classic Load Balancer. In this video, our expert sheds light on the differences between the three types of load balancers.
The Application Load Balancer works at the request level and routes traffic to targets such as EC2 instances, IP addresses, Lambda functions and containers on the basis of content in the request. It can provide sophisticated request routing oriented towards delivering modern application architectures such as container-based and microservices applications.

The Network Load Balancer works at the connection level, enabling users to route connections to targets such as instances, containers and microservices within Amazon VPC on the basis of IP protocol data. It serves ideal load balancing functionality for UDP and TCP traffic.

The final entry in this video, Classic Load Balancer is suitable for basic load balancing functionality throughout different Amazon EC2 instances. The classic load balancer works at connection level and request level.

Why did you choose network load balancer for your example and not application load balancer?

[RBNrocks]

In the Application Load balancer if the server which serves BAR requests go down, what would happen?

[MrKiraBR]

If you have an application that runs in port 8080, how would you do to access it? Just put load-balancer-url:8080 ?
