Elastic Load Balancer Documentation

Security

When using Amazon Virtual Private Cloud (VPC), you can create and manage security groups associated with Elastic Load Balancing to provide additional networking and security options for Application Load Balancer, Network Load Balancer, and Classic Load Balancer. You can configure the Load Balancers to be Internet facing or create a load balancer without public IP addresses to serve as an internal (non-internet-facing) load balancer.

Availability

An Elastic Load Balancer is designed to be available. You can distribute incoming traffic across your Amazon EC2 instances in a single Availability Zone or multiple Availability Zones. An Elastic Load Balancer is designed to scale its request handling capacity in response to incoming application traffic. Elastic Load Balancer is also designed to run health checks on targets on a configurable cadence.

Throughput

Elastic Load Balancer is designed to handle traffic as it grows and can load balance and handle traffic patterns.            

Health checks

An Elastic Load Balancer is designed to route traffic to healthy targets such as EC2 instances, containers, IP addresses, microservices, Lambda functions, and appliances. With Elastic Load Balancing, you can get (1) health check improvements to help configure detailed error codes and (2) new metrics designed to give insight into traffic for each of the services running on an EC2 instance.      

Sticky sessions

Sticky sessions are a mechanism designed to route requests from the same client to the same target. Elastic Load Balancers are designed to support sticky sessions. Stickiness is defined at a target group level.      

Delete protection

You can enable deletion protection on an Elastic Load Balancer, which is designed to prevent it from being accidentally deleted.
