Load Balancing

Load Balancing helps you with proper distribution of traffic on multiple servers so that at the time of high traffic, your services won’t get affected. We use AWS load balancer which forwards the traffic across multiple targets (say EC2 instances) depending upon their availability. It is termed as an Elastic load balancer. ELB can automatically scale its request handling capacity to meet the demands of incoming traffic, justifying the term elastic associated with it.

AWS Elastic Load Balancer provides various benefits which are as follows –

• Elasticity
  Elastic Load Balancing automatically scales its request handling capacity to meet the demands of application traffic.
• Security
  AWS provides VPC feature which helps you to connect your web server locally with the load balancer and secure your application servers from direct public access.
• Availability
  Achieve higher levels of fault tolerance for your applications by using Elastic Load Balancing to automatically route traffic across multiple instances and multiple Availability Zones.
