Pool members are no longer automatically added or removed on a VE pool configured to use autoscale.
1. Boot up a VE instance on AWS using the BYOL marketplace image version 12.0.0.0.2.606. 2. Create autoscale group on AWS based on load requirements. 3. Configure pool autoscaling on VE (i.e., configure autoscale iApp, iCall, etc.).
Create the following symlink in /opt/aws/: ln -s ec2-api-tools-1.7.5.1 ec2-api-tools-1.6.13.0
Include Amazon EC2 web service tools from latest version of the toolset. Included is support for AWS pool autoscale functionality.
