Load Balancers & Auto Scaling: Network Load Balancer

My Saved Presets

Configuration to create a Network Load Balancer (NLB), target groups and listeners in an AWS VPC to load balance incoming traffic to targets such as EC2 instances or ALBs. The NLB also includes health checks to ensure the state of the targets before forwarding traffic.

This template includes settings for configuring:

Load balancer Name and Schema (Internet vs Internal)
Subnet Mapping to set network settings
Deletion Protection to prevent the load balancer from being deleted accidentally
Enabling S3 Access Logging to log requests processed by the load balancer
Target Groups to configure the destination for the load balancer:
- Target Type can be an EC2 instance, IP address or ALB and Target Id
- Protocol, Protocol Version, and Port
- If HTTPS is selected, then SSL policy and Certifiacte ARN must be provided
- Health Check settings such as path, interval, etc.
Listeners to specify the ports the load balancer accepts connections on:
- Protocol and Port number
- Actions such as Forward, Fixed-Response or Redirect
Load Balancer Attributes such as Cross Zone Load Balancing
