<!--END STABILITY BANNER-->

The `@aws-cdk/aws-elasticloadbalancing` package provides constructs for configuring
classic load balancers.

## Configuring a Load Balancer

Load balancers send traffic to one or more AutoScalingGroups. Create a load
balancer, set up listeners and a health check, and supply the fleet(s) you want
to load balance to in the `targets` property.

```ts
declare const vpc: ec2.IVpc;
const lb = new elb.LoadBalancer(this, 'LB', {
  vpc,
  internetFacing: true,
  healthCheck: {
    port: 80,
  },
});

declare const myAutoScalingGroup: autoscaling.AutoScalingGroup;
lb.addTarget(myAutoScalingGroup);
lb.addListener({
  externalPort: 80,
});
```

The load balancer allows all connections by default. If you want to change that,
pass the `allowConnectionsFrom` property while setting up the listener:

```ts
declare const mySecurityGroup: ec2.SecurityGroup;
declare const lb: elb.LoadBalancer;
lb.addListener({
  externalPort: 80,
  allowConnectionsFrom: [mySecurityGroup],
});
```
