This checklist summarizes the tasks required to use Auto Scaling with BIG-IP® VE.
If you want to use metrics provided by BIG-IP, complete the following steps.
|Enable CloudWatch detailed monitoring||Select this option.|
|Advanced Details > IP Address Type > Assign a public IP address to every instance||Select this option. BIG-IP VE must access the internet when it launches, so it can be licensed with F5.|
|Advanced Details > User data > As text||If you want to use different credentials to launch new instances, enter this text:
|Configure Security Group||Select an existing group that is associated with the VPC.|
|Group name||Type the name of the Auto Scaling group you created in tmsh.|
|Network and Subnet||Select the virtual private cloud (VPC) and its subnet (10.0.0.0/24).|
|Receive traffic from Elastic Load Balancer(s)||Select this check box and choose your ELB. This ensures that traffic flows from AWS ELB load balancer to the BIG-IP VE instances.|
|Use scaling policies to adjust the capacity of this group||Set the minimum and maximum number of instances and add an alarm.
If you want to use BIG-IP metrics to trigger scaling of BIG-IP instances, from the Execute policy when list, select the CloudWatch alarm you created previously.
