Create a Big-IQ Service Scaling Group

A Service Scaling Group will automatically:

  • Deploy a per-app or shared platform Big-IP VE
  • Deploy application services
  • Configure an upstream AWS L4 load-balancer to scale out F5 Big-IP VE’s in AWS based on throughput, high cpu, and other metrics.
  • Collect comprehensive analytics

In Big-IQ, Applications => ENVIRONMENTS => Service Scaling Groups => Create New Service Scaling Group.
