Learn all about how the AWS autoscaling template version
1.2 and earlier help you secure applications.
The auto scaling template version 1.2 deploys the VM-Series
in an ELB sandwich topology with an internet-facing classic ELB
and an either an internal classic load balancer or an internal application
load balancer (internal ELB). The internet-facing ELB is accessible
from the internet and distributes traffic that enters the VPC across
a pool of VM-Series firewalls. The firewalls then redirect traffic
using NAT policy to the internal ELB. The internal ELB, which is
only accessible inside the VPC, distributes traffic to an auto scaling
tier of web servers. The API integration with AWS CloudWatch allows
the CloudWatch service to monitor the health and resource load on
the EC2 instances—VM-Series firewalls and web servers—and then use
that information to trigger a scale in or scale out event in the
respective Auto Scaling Group (ASG).
