Introduction to AWS Elastic Load Balancer — What is ELB?

AWS Elastic Load Balancer (ELB)

AWS Elastic Load Balancer (ELB) automatically distributes your incoming traffic across multiple targets, such as EC2 instances, containers, and IP addresses, in one or more Availability Zones.

It can automatically scale to the vast majority of workloads.

  • Application Load Balancer (ALB)
  • Network Load Balancer (NLB)
  • Gateway Load Balancer (GWLB)
  • Classic Load Balancer (CLB)

Difference between Application load balancer and Network…
