Configure load balanced gateway

Lightwing supports two kinds of load balanced gateways.

1. ELB based gateway
2. Instance based load balanced gateway

Add a new gateway

• Navigate to Autostopping on the left menu
• Click on Add gateway button
• And choose Loadbalanced
• Click Next

Configure gateway details

• Name: Enter a DNS complaint name for the gateway. Name has to be unique among other gateways in the organization
• Port: The port in which traffic will be received
• Idle time: Idle time in minutes. When lightwing detects no traffic for the idle time, it will stop the instance

ELB based gateway

In a ELB based gateway, lightwing will adjust the autoscaling group’s desired capacity when performing idle time optimization. When lightwing detects traffic, it will change the desired capacity to service the traffic.

• Choose ELB from Loadbalancer field
• Scaling group name: Enter autoscaling group that ELB uses
• Desired capacity: Current desired capacity configured at the autoscaling group
• Loadbalancer URL: without scheme (http/https)
• Click on Save gateway to save the gateway configuration.

Instance based gateway

Instance based gateway configuration can be used when you have one or more instances that are acting as a loadbalancer. These instances will have a load balancer like HAProxy/Nginx installed to handle the traffic.

When configuring instance based load balanced gateway, lightwing will need to select two sets of resources, load balancers and cluster members.

• Loadbalancer filter: Filter text to select resources which are loadbalancers. Lightwing will evaluate filter text and forward traffic to the matching instances

• Cluster members filter: Filter text used to select the cluster members

• Click on Save gateway to save the gateway configuration.
