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.
