https://fortinetcloudcse.github.io/Autoscale-Simplified-Template/2_autoscale_considerations/index.htmlBefore investing time in this deployment, it is worth asking whether autoscale is the right architecture for your use case. Our general recommendation is to consider intentional scaling — using Terraform to preemptively manage instance count — before committing to an autoscale deployment. Most customers, once they understand the trade-offs, choose intentional scaling over autoscale. If you can make that case to your customer, you should. Reasons to Reconsider Autoscale Scale-Out Latency A new FortiGate instance takes approximately 4-5 minutes to deploy, license, and become traffic-ready. If the burst event that triggered the scale-out lasts less than 4-5 minutes, the new instance will be ready after the event has already passed. In many cases, autoscale provides no benefit for short-duration bursts.Hugoen-US
