Elastic Load Balancer

What is a load balancer?

A load balancer accepts incoming network traffic from a client-side, and based on some algorithm it distributes the traffic out of it to one or more backend servers:

Features of Elastic load balancer:

High availability

Elastic Load Balancing distributes traffic across all the targets that are configured.

Health checks

In Elastic Load Balancing, health checks are performed to identify unhealthy targets and stop sending traffic to them. Besides, it sends the traffic only to the remaining healthy targets.

Types of Elastic Load Balancer

1. Application Load Balancer
2. Network Load Balancer
3. Classic Load Balancer

Understanding the Classic Load Balancer

The Classic Load Balancer is a feature-rich balancing that provides high availability, monitoring, and better security for your application stack.

The AWS Classic Load Balancer (CLB) runs at Layer 4 of the OSI model. This indicates that the load balancer routes traffic between clients and backend servers based on IP address and TCP port.

Understanding the Application Load Balancer

AWS Application Load Balancer operates at Layer 7 of the OSI model. One of the rich features of the application load balancer is Content-based routing. It has the ability to support multiple domains using a single load balancer. Route each path or hostname to a different target group.  Application load balancer allows for multiple services to be hosted behind a single application load balancer.

Understanding the Network Load Balancer

Network Load Balancer operates at the connection level (Layer 4), routing connections to targets - EC2, Containers – within VPC based on IP protocol data. As a Network load balancer is capable of handling millions of requests per second while maintaining ultra-low latencies, it is ideal for both TCP and UDP traffic. The Network Load Balances integrates with popular AWS services such as Auto Scaling, Amazon EC2 Container Service (ECS), Amazon CloudFormation, and AWS Certificate Manager (ACM).
